slippery-chicken-edit/add-arrow-to-events [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DATE
April 9th 2012
DESCRIPTION
Adds an arrow above the specified notes of a slippery-chicken object, coupled with text to be printed in the score at the start and end of the arrow. Can be used, for example, for transitions from one playing state to another. If no text is desired, this must be indicated by a space in quotes (" ") rather than empty quotes (""). See also the add-arrow method in the event class.
ARGUMENTS
- A slippery-chicken object. - A text string for the beginning of the arrow. - A text string for the end of the arrow. - A list that is the starting event reference, in the form (bar-number event-number). Event numbers count from 1 and include rests and tied notes. - A list that is the end event reference, in the form (bar-number event-number). - The ID of the player to whose part the arrow should be attached.
OPTIONAL ARGUMENTS
- T or NIL to indicate whether or not to print a warning when trying to attach an arrow and accompanying marks to a rest. T = print warning. Default = NIL.
RETURN VALUE
T

slippery-chicken-edit/add-auxiliary-notes [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DATE
May 26th 2016, Edinburgh
DESCRIPTION
Analyses phrase by phrase to find the most frequent X notes then changes some of them (according to an activity-levels object) to auxiliary notes (up a semitone by default). Chords are ignored.
ARGUMENTS
- the slippery-chicken object
OPTIONAL ARGUMENTS
keyword arguments - :players. A single player (symbol) or list of players to process. If NIL then all players will be processed. - :start-bar. An integer indicating the bar in which the processes should start. Default = NIL which means we'll start at the beginning. - :end-bar. An integer indicating the bar in which the processes should stop. Default = NIL which means we'll process through to the end - :verbose. T or NIL to print information about the pitch changes during the process. Default = NIL. - :ignore. A symbol or pitch-object (or list thereof) to represent pitches which should not be processed. Default = NIL = process (potentially) all pitches. - :activity-level. Whether to change the note is decided by an activity-levels object. This argument determines the 'level' argument used in that class's active method. Default = 5 = 50% of the notes will be changed. NB The activity-levels object will be reinitialised for each phrase so the 50/50 spread might not be obvious. - :num-notes. The number of notes to process per phrase. We calculate the most used pitches in every phrase then use this number of pitches to add auxiliaries to. Default = 3. - :intervals. The intervals that the original pitches will be transposed by to create the auxiliary notes. This can be a single value in semitones or a list of values. The list does not have to have the same length as :num-notes as it will be cycled through when necessary. Default = 1.
RETURN VALUE

slippery-chicken-edit/add-half-beat-rest [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DATE
August 26th 2016, Edinburgh
DESCRIPTION
Calls the method of the same name on each rthm-seq-bar object at the given bar number. Adds a half beat rest at the end of the bar. This is a destructive method. It will change the time signature, so a 2/4 bar becomes a 5/8 bar, with an 1/8th rest at the end. This is done for all the players in the ensemble (so that scores can be correctly written)
ARGUMENTS
- a slippery-chicken object
OPTIONAL ARGUMENTS
- the bar number to modify. Default = 1.
RETURN VALUE
T

slippery-chicken-edit/add-mark-all-players [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
Add a specified mark to a specified event in the parts of all players. The event can either be specified as a 1-based integer, in which case the mark will be attached to the same event in all parts, or as a list of integers, in which the mark is attached to different events in the same bar for each player, passing from the top of the ensemble downwards.
ARGUMENTS
- A slippery-chicken object. - An integer that is the bar number or a list of integers that is a reference to the bar number in the form (section sequence bar). - An integer that is the event to which to attach the specified mark in all parts, or a list of integers that are the individual events to which to attach the mark in the consecutive players. - The mark to be added.
RETURN VALUE
Always returns T.
EXAMPLE

DESCRIPTION
Add marks in a somewhat more free list form, with the option of implementing a user-defined shorthand.
ARGUMENTS
- A slippery-chicken object. - A list of lists containing the players, bar and note refs, and marks to be added. The first element of each contained list will be the ID of the player to whose part the marks are to be added followed by a pattern of <mark bar-number note-number> triplets, or if a mark is to be added repeatedly then <mark bar note bar note... >. A mark can be a string or a symbol.
OPTIONAL ARGUMENTS
keyword arguments:
- For marks given as symbols, the user can supply a shorthand table that
will expand an abbreviation, such as sp, to the full mark name, such as
short-pause. This table takes the form of a simple Lisp association list,
e.g.: '((al aeolian-light)
(ad aeolian-dark)
(wt "WT")
(h harm))
- :warn. T or NIL to indicate whether to print a warning for unrecognized
marks. T = print warning. Default = T.
- :verbose. T or NIL to indicate whether the method is to print verbose
feedback about each mark added to the Listener. T = print feedback.
Default = NIL.
RETURN VALUE
Returns NIL.

DESCRIPTION
Add a player to the ensemble and piece slots/objects of the given slippery-chicken object. This clones the section/sub-section structure of the slippery-chicken object, creating all the necessary data structures for empty bars in the right meter, tempo etc. NB As this method may be called several times successively, it's the caller's duty to call (update-slots sc) in order to have timing and other data updated correctly.
ARGUMENTS
- the slippery-chicken object - a player object or symbol ID for the new player
OPTIONAL ARGUMENTS
keyword arguments: - :instrument. a symbol ID for an existing instrument in the instrument-palette (the next argument). This is actually required unless the default of 'computer is acceptable or a player object is passed as second argument. - :instrument-palette. an instrument-palette object in which the instrument exists. Default is the standard palette. - :midi-channel. the midi-channel for the new player - microtones-midi-channel. the microtones-midi-channel for the new player
RETURN VALUE
the new player object from the ensemble slot of the slippery-chicken object

slippery-chicken-edit/auto-accidentals [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
Automatically determine which notes in each bar need accidentals and which don't. This method also places cautionary accidentals (in parentheses) based on how many notes back the last occurrence of that note/accidental combination appeared in the bar. The first optional argument to the method allows the user to specify how many notes back to look. NB: As both cmn-display and write-lp-data-for-all call respell-notes by default, that option must be set to NIL for this method to be effective (see below).
ARGUMENTS
- A slippery-chicken object.
OPTIONAL ARGUMENTS
- An integer that is the number of notes back to look when placing cautionary accidentals in parentheses. If the last occurrence of a given repeated note/accidental combination was farther back than this number, the accidental will be placed in the score in parentheses.
RETURN VALUE
Returns NIL.

DESCRIPTION
Automatically places indications for beam start- and end-points (1 and 0) in the BEAMS slot of the corresponding event objects. By default, this method determines the start and end indications for beams on the basis of the beat found in the time signature, but the user can specify a different beat basis using the first optional argument.
ARGUMENTS
- A slippery-chicken object.
OPTIONAL ARGUMENTS
- NIL, an integer that is a power-of-two rhythmic duration, or the alphabetic representation of such a rhythm to specify the beat basis for setting beams (e.g. 4 or 'h). - T or NIL to indicate whether the method is to check whether an exact beat of rhythms can be found for each beat of the bar. If T, a warning will be printed when an exact beat cannot be found for each beat of the bar. Default = T. - players, a single symbol or list of players to process. Default = NIL = process all players in the ensemble
RETURN VALUE
Returns NIL.

[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
Automatically create clef changes in the specified player's or players' part or parts by adding the appropriate clef symbol to the MARKS-BEFORE slot of the corresponding event object. This routine will only place clef symbols that are present in the given instrument object's CLEFS slot. This method is called automatically by cmn-display and write-lp-data-for-all, with the delete-clefs option set to T. NB: While this routine generally does a good job of putting the proper clefs in place, it will get confused if the pitches in a given player's part jump from very high to very low (e.g. over the complete range of the piano).
ARGUMENTS
- A slippery-chicken object.
OPTIONAL ARGUMENTS
keyword arguments: - :verbose. T or NIL to indicate whether the method is to print feedback about its operations to the Listener. T = print feedback. Default = NIL. - :in-c. T or NIL to indicate whether the pitches processed are to be handled as sounding or written pitches. T = sounding. Default = T. - :players. A list containing the IDs of the players whose parts are to be to have clefs automatically added. - :delete-clefs. T or NIL to indicate whether the method should first delete all clef symbols from the MARKS-BEFORE slots of all event objects it is processing before setting the automatic clef changes. - :delete-marks-before. T or NIL to indicate whether the MARKS-BEFORE slot of all event objects processed should first be set to NIL. T = set to NIL. Default = NIL.

slippery-chicken-edit/auto-slur [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
Automatically add slurs to note groups in the specified measure range of a given player's part. This method places slurs above all consecutive notes between rests. If a value is specified for :end-bar and the last event in the end bar is not a rest, the final sequence of attacked notes in that bar will not be slurred. NB: Slurs will automatically stop at repeated pitches. Staccato marks will not stop the auto-slurring process but staccatos can be removed (see below).
ARGUMENTS
- A slippery-chicken object. - A player ID or list of player IDs for the parts in which the slurs are to be placed.
OPTIONAL ARGUMENTS
keyword arguments: - :start-bar. An integer that is the first bar in which to automatically place slurs. - :end-bar. An integer that is the last bar in which to automatically place slurs. - :rm-slurs-first. T or NIL to indicate whether to first remove existing slurs from the specified region. NB: If you already have slur marks attached to events, setting this to NIL can produce unwanted results caused by orphaned beg-slur or end-slur marks. T = remove existing slurs first. Default = T. - :rm-staccatos. T or NIL to indicate whether to first remove existing staccato, tenuto, and accented staccato marks from the specified region. T = remove staccatos. Default = NIL. - :over-accents. T or NIL. Default = T. - :verbose. T or NIL to indicate whether to print feedback from the process to the Lisp listener. T = print. Default = NIL.
RETURN VALUE
A list of sublists, each of which contains the start and end event, plus the number of notes under the slur, for each slur added.

slippery-chicken-edit/bars-to-sc [ Functions ]
[ Top ] [ slippery-chicken-edit ] [ Functions ]
DESCRIPTION
Take a list of rthm-seq-bars and add them to a new or existing slippery-chicken object. It works in three different ways: 1. Create a new slippery chicken object with one player and one section. 2. Add new parts to an already existing section in an already exisiting slippery chicken object. 3. Add a new section to an already exisiting part in and already exisiting object. In the second case, we assume you are creating a slippery chicken object part by part with this function. It is not currently possible to add a part like this in the middle of the score--the new part will be added to the end of the last group of the ensemble (bottom of score) so make sure to add parts in the order you want them. In the third case, you can add a new section to an exisitng part, but you cannot add a new section to a part that does not exist. NB Bear in mind that if you want to use midi-play, then the events in the bars will need to have their midi-channel set (e.g. via make-event). It's also the caller's responsibility to ensure that the parts added have the same time-signature structure as any existing part.
ARGUMENTS
- A list of rthm-seq-bars
OPTIONAL ARGUMENTS
keyword arguments: - :sc. Either an existing slippery-chicken object or nil if one should be created automatically. If nil, the following three arguments must be specified, otherwise they will be ignored. Default = NIL. - :sc-name. The name (symbol) for the slippery-chicken object to be created. This will become a global variable. Default = '*auto*. - :player. The name (symbol) of the player to create. Default = 'player-one. (Remember that Lilypond has problems with player names with numbers in them :/ ) - :instrument. The id (symbol) of an already existing instrument in the instrument-palette. Default = 'flute. - :update. Whether to call update-slots on the new slippery-chicken object (to update timing info. etc.). Default = T. - :section-id. The section id. Default = 1. - :tempo. The tempo in BPM for the whole slippery-chicken object (piece). - :midi-channels. A 2-element list specifying the midi-channels for the chromatic and microtonal notes of the player. This will not change channels of the events in the bars but is assumed to correspond to those.
RETURN VALUE
A slippery-chicken object.

slippery-chicken-edit/change-pitch [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
Change the pitch of a specified event to a new specified pitch. The new pitch is not required to be a member of the current set. NB The new pitch is the sounding pitch if a transposing instrument, unless optional argument is set to T. NB In the case of ties, this doesn't update the following 'tied-to' notes but see the documentation for the change-pitches method below (or call check-ties, which fixes them too).
ARGUMENTS
- A slippery-chicken object. - An integer that is the bar number in which the pitch is to be changed. - An integer that is the number of the note in the specified bar whose pitch is to be changed (1-based). - The ID of the player for whom the pitch is to be changed. - A note-name symbol that is the new pitch.
OPTIONAL ARGUMENTS
T or NIL to indicate whether the written or sounding pitch should be changed. Default = NIL (sounding).
RETURN VALUE
Returns T.

slippery-chicken-edit/change-pitches [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
Change the pitches of the specified event objects for a given player to the specified new pitches. If the new pitches are passed as a simple flat list, the method will just change the pitch of each consecutive attacked event object (with NIL indicating no change), moving from bar to bar as necessary, until all of the specified new pitches are used up. Also, if a flat list is passed, each new pitch specified will be applied to each consecutive attacked note; i.e., ties don't count as new pitches. Tied-to events are left with the old pitch information, which is of course a potential problem. When generating scores though, we usually call respell-notes, which calls check-ties, which corrects spellings of tied-to notes and therefore in effect changes those notes too. So generally, we don't have to worry about this, but if you explicitly tell slippery chicken not to respell notes, you'll need to call check-ties with the first optional argument as T. Also see the documentation in the bar-holder class for the method of the same name. NB As various methods (e.g. transposition, change-pitch(es)) in various classes (slippery-chicken, bar-holder, rthm-seq-bar, rthm-seq) may change pitch information and midi-channels stored in events, chords, pitches, etc. it is recommended to call the slippery-chicken reset-midi-channels method before calling midi-play, if any of those methods have been used. This way midi channels for pitches belonging to particular players will use channels originally allocated in the ensemble for chromatic and microtonal pitches, no matter where they originated or how they were changed.
ARGUMENTS
- A slippery-chicken object. - The ID of the player whose part is to be modified. - An integer that is the number of the first bar whose pitches are to be modified. - A list note-name symbols and NILs, or a list of lists of note-name symbols and NILs, which are the new pitches. If a simple flat list, see the comment in the description above. If a list of lists, each sub-list will represent a full bar; e.g., (change-pitches bh 'vla 5 '((g3 gs4) nil (nil nil aqf5))) will change the pitches in bars 5 and 7 (for the player 'vla), whereas bar six, indicated by nil, wouldn't be changed; similarly the first two notes of bar 7, being nil, will also not be changed, but note 3 will.
OPTIONAL ARGUMENTS
keyword arguments: - :use-last-octave. T or NIL to indicate whether or not each consecutive new pitch listed will automatically take the most recent octave number specified; e.g. '((a3 b g cs4)). T = use last octave number. Default = T. - :marks. A list of marks to be added to the events objects. This option can only be used in conjunction with the simple flat list of pitches. In this case the list of pitches and list of marks must be the same length and correspond to each other item by item. Sub-lists can be used to add several marks to a single event. NB: See cmn.lsp::get-cmn-marks for the list of recognised marks. If NIL, no marks will be added. Default = NIL. - :written. T or NIL to indicate whether these are the written or sounding notes for a transposing instrument. Default = NIL. - :warn. If there are more pitches in the given list than there are events in the slippery-chicken structure, issue a warning, unless NIL. Default = T.
RETURN VALUE
If the new pitches are passed as a simple flat list, the method returns the number of the bar in which the pitches were changed; otherwise returns T.

slippery-chicken-edit/double-events [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DATE
20-Jul-2011 (Pula)
DESCRIPTION
Copy the specified events from one player to the corresponding bars of one or more other players. NB: Although partial bars can be copied from the source player, the entire bars of the target players are always overwritten, resulting in rests in those segments of the target players' bars that do not contain the copied material. This method thus best lends itself to copying into target players parts that have rests in the corresponding bars.
ARGUMENTS
- A slippery-chicken object. - The ID of the player from whose part the events are to be copied. - The ID or a list of IDs of the player or players into whose parts the copied events are to be placed. - An integer that is the number of the first bar from which the events are to be copied. - An integer that is the number of the first event to be copied from the specified start bar. This number is 1-based and counts rests and ties. - An integer that is the number of the last bar from which the events are to be copied. - NIL or an integer that is the number of the last event to be copied from the specified end bar. This number is 1-based and counts rests and ties. If NIL, all events from the given bar will be copied.
OPTIONAL ARGUMENTS
keyword arguments: - :transposition. A positive or negative number that is the number of semitones by which the copied material is to be first transposed. This number can be a decimal number, in which case the resulting pitches will be rounded to the nearest microtone (if the current tuning environment is capable of microtones). - :consolidate-rests. T or NIL to indicate whether resulting consecutive rests should be consolidated each into one longer rest. T = consolidate. Default = T. - :update. T or NIL to indicate whether to update the slots of the given slippery-chicken object after copying. T = update. Default = T. - :auto-beam. T or NIL to indicate whether to call auto-beam on the doubled notes. Default = T. - :pitches. T or NIL to indicate whether pitch information should be copied over. This would usually be T but some methods might just want to duplicate events as rests (e.g. orchestrate). Default = T.
RETURN VALUE
Returns T

slippery-chicken-edit/double-player-inverted [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DATE
July 14th 2020, Heidhausen
DESCRIPTION
Add a new player to the ensemble/piece, double the events of an existing player, then use the invert method for each bars within the given range to turn rests into notes and vice-versa. To choose new notes we use curves to limit high and low, using the sets (from the map) used to generate the existing voices.
ARGUMENTS
- the slippery-chicken object - the ID of a new player (symbol) - the instrument for the new player (must be in the instrument-palette) - the ID of the existing player whose events are inverted (symbol) - a curve for the maximum upper notes - a curve for the maximum lower notes. Both these curves can have any arbitrary x range but the y values should use MIDI note numbers or note symbols. Note that the x range will be stretched over the number of bars in the piece, not the given bar range, so that the bar number can be used for interpolation. - a curve to decide whether to actually play a note in the new part or not. This can also have any arbitrary x range and will also be stretched over the number of bars in the piece, but the y range should be from 0 to 10 as the interpolated value for the notes in each bar is passed to an activity-levels object to determine whether to play or not.
OPTIONAL ARGUMENTS
keyword arguments: :start-bar :start-event :end-bar :end-event. These are passed to double-events. See that method for details but note that the defaults for the end-* arguments are NIL which in turn default to the last bar/event. :reset-midi-channels. T or NIL to reset all events in the slippery-chicken object to the original midi channels of the parent player. Default = T.
RETURN VALUE
the (modified) slippery-chicken object
SYNOPSIS

slippery-chicken-edit/enharmonic-spellings [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
Change the pitch of specified event objects to their enharmonic equivalents. This takes as its second argument a list of lists, each of which consists of the ID of the player whose part is to be altered and a series of bar-number/event-number pairs, where (2 3) indicates that the pitch of the third event of the second bar is to be changed to its enharmonic equivalent. Pitches within chords are specified by following the bar number with a 2-item list consisting of the event number and the number of the pitch within the chord, counting from low to high, where (2 (2 4)) indicates that the fourth pitch from the bottom of the chord located in the second event object of bar 2 should be changed to its enharmonic equivalent. An optional T can be included to indicate that the written pitch is to be changed, but not the sounding pitch, as in (cl (3 4 t)). NB: In order for this method to work, the :respell-notes option of cmn-display and write-lp-data-for-all must be set to NIL.
ARGUMENTS
- A slippery-chicken object. - The list of changes to be made, in the format '((player changes...)), e.g.: '((cl (3 3 t) (3 4 t)) (pn (2 (2 4))) (vc (1 1) (1 3) (1 4) (1 6)))

slippery-chicken-edit/enharmonics [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
Change the sharp/flat pitches of a specified region of a specified player's part to their enharmonic equivalent. NB: This method only affects pitches that already have sharp/flat accidentals. It does not affect "white-key" notes (e.g. C-natural = B-sharp etc.) NB: As the cmn-display and write-lp-data-for-all methods call :respell-notes by default, this option must be explicitly set to NIL for this method to be effective.
ARGUMENTS
- A slippery-chicken object. - An integer or a 2-item list of integers that indicates the first bar in which the enharmonics are to be changed. If an integer, the method will be applied to all sharp/flat pitches in the bar of that number. If a 2-item list of integers, these represent '(bar-number note-number). The note number is 1-based and counts ties. If nil, it defaults to 1. - An integer or a 2-item list of integers that indicates the last bar in which the enharmonics are to be changed. If an integer, the method will be applied to all sharp/flat pitches in the bar of that number. If a 2-item list of integers, these represent '(bar-number note-number). The note number is 1-based and counts ties. If nil it defaults to (num-bars sc) - The ID of the player or players whose part is to be changed. If nil, the method will be applied to all players.
OPTIONAL ARGUMENTS
keyword arguments - :written. T or NIL to indicate whether to change written-only pitches or sounding-only pitches. T = written-only. Default = T. - :pitches. NIL or a list of note-name symbols. If NIL, all sharp/flat pitches in the specified region will be changed to their enharmonic equivalents. If a list of one or more note-name symbols, only those pitches will be affected. - :force-naturals. T or NIL to indicate whether to force "natural" note names that contain no F or S in their name to convert to their enharmonic equivalent (ie, B3 = CF4). NB double-flats/sharps are not implemented so this will only work on F/E B/C.
RETURN VALUE
Returns T.

slippery-chicken-edit/force-artificial-harmonics [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
For string scoring purposes only: Transpose the pitch of the given event object down two octaves and add the harmonic symbol at the perfect fourth. If this results in a fingered pitch (or even a touched perfect fourth) that is out of the range of the instrument, a warning will be printed to the Listener, the pitch will not be transposed, and the harmonic diamond will not be added. NB This method assumes the player doesn't change instrument during the bars to be processed.
ARGUMENTS
- A slippery-chicken object. - The ID of the player whose part is to be changed. - An integer that is the number of the first bar in which artificial harmonics are to be created. - An integer that is the number of the first event in that bar that is to be changed into an artificial harmonic. - An integer that is the number of the last bar in which artificial harmonics are to be created.
OPTIONAL ARGUMENTS
- An integer that is the number of the first event in that bar that is to be changed into an artificial harmonic. If no end-event is specified, all event objects in the last bar will be changed to artificial harmonics. - T or NIL to trigger warnings when forcing would take a fingered pitch out of the instrument's range, or when we encounter chords or rests - T or NIL to force natural-harmonics to become artificial. Default = T.
RETURN VALUE
Returns T.

DESCRIPTION
Force all pitches (and chords) to be within the range of the instruments who play them. Of course this is usually a part of the slippery-chicken pitch selection algorithm but sometimes we change pitches (algorithmically in particular) and this might bring them out of range. Notes that are out of range will be transposed up and down the required number of octaves. This applies to single pitches in chords also. Instrument changes will be respected on a bar-by-bar basis. See also the three force-in-range methods in instrument.lsp

[ Top ] [ slippery-chicken-edit ] [ Methods ]
DATE
October 4th 2019
DESCRIPTION
Yamaha Disklavier pianos can't play a note immediately after a note-off. The hammer needs a little time to return to its 'off' position before it can be used to restrike a note. Tests show this time to be around 60 milliseconds. of course this will be instrument-dependent, so a little experimentation might be needed. This method will go through each event and decrement those events which repeat a note on the same MIDI channel which start < 'min-time' after the end-time of the previous event.
ARGUMENTS
- the slippery-chicken object - either a single symbol or a list of symbols for the players to be processed
OPTIONAL ARGUMENTS
keyword arguments - :start-bar. The bar at which to begin processing (integer). Default = 1. - :end-bar. The bar at which to end processing (integer). Default = NIL = last bar - :min-gap. The minimum time the hammer needs to return, in milliseconds. Default = 60. - :min-dur. The minimum duration of a note in milliseconds, after reducing duration. Default = 50 milliseconds.
RETURN VALUE
A list of the number of notes affected per player.

If NIL then all players will be processed. - The method or function itself. This can be a user-defined function or the name of an existing method or function. It should take at least one argument, a rthm-seq-bar, and any other arguments as supplied.
OPTIONAL ARGUMENTS
- Any additional argument values the specified method/function may take or require. See the thin method below for an example that uses additional arguments.
RETURN VALUE
- A list of the rthm-seq-bar objects that were modified. NB This might be a long list, and, depending on your Lisp implementation, formatting of the bars might cause Lisp to appear to 'hang'.

- A slippery chicken object - A number that is the first bar to which the function should be applied. Default = NIL in which case 1 will be used. - A number that is the last bar to which the function should be applied. Default = NIL in which case all bars will be processed. - A list of the IDs of the players to whose parts the function should be applied. Can also be a single symbol. If NIL then all players will be processed. - The method or function itself. This can be a user-defined function or the name of an existing method or function. It should take at least one argument, an event, and any other arguments as supplied.
OPTIONAL ARGUMENTS
- Any additional argument values the specified method/function may take or require. See the thin method below for an example that uses additional arguments.
RETURN VALUE
- A list containing the number of events changed per instrument

DESCRIPTION
A simple method that mimics the behaviour of map-over-bars but on notes instead. At its heart is a next-event loop. Use this method to apply an arbitrary function to every note within a specific range of bars. NB This works on NOTES only, rests will be skipped!
ARGUMENTS
- A slippery chicken object - A number that is the first bar to which the function should be applied. Default = NIL in which case 1 will be used. - A number that is the last bar to which the function should be applied. Default = NIL in which case all bars will be processed. - A list of the IDs of the players to whose parts the function should be applied. Can also be a single symbol. If NIL then all players will be processed. - The method or function itself. This can be a user-defined function or the name of an existing method or function. It should take at least one argument, a note event (can be a single pitch or a chord), and any other arguments as supplied.
OPTIONAL ARGUMENTS
- Any additional argument values the specified method/function may take or require. See the thin method below for an example that uses additional arguments.
RETURN VALUE
- A list containing the number of notes changed per instrument

DESCRIPTION
Apply a function to each sequenz object in a slippery-chicken piece. Note that as a sequenz is a subclass of rthm-seq (and bar-holder) and that rthm-seq has its rthm-seq-bars in the bars slot, we've got access to all kinds of data which we can switch on in the function passed here, e.g. player-section-ref, rsp-id
ARGUMENTS
- the slippery-chicken object - the player(s) to process (single or list of symbols). If nil then all players will be processed. - the function to apply to each sequenz. This should accept a sequenz object as its first argument.
OPTIONAL ARGUMENTS
&rest: further arguments to be passed to the given function

DESCRIPTION
Move a specified clef from a specified event object to another. NB: As the :auto-clefs option of cmn-display and write-lp-data-for all first deletes all clefs before automatically placing them, this argument must be set to NIL. The auto-clefs method can be called outside of the cmn-display or write-lp-data-for-all methods instead.
ARGUMENTS
- A slippery-chicken object. - An integer that is the number of the bar in which the given clef is located. - An integer that is the number of the event object in the given bar to which the given clef is attached. - An integer that is the number of the bar to which the given clef is to be moved (this can be the same bar). - An integer that is the number of the event object in the new bar to which the given clef is to attached. - The ID of the player in whose part the clef is to be moved.
RETURN VALUE
Returns the value of the MARKS-BEFORE slot of the event object to which the clef is moved.

[ Top ] [ slippery-chicken-edit ] [ Methods ]
DATE
20-Jul-2011 (Pula)
DESCRIPTION
Move a specified sequence of consecutive event objects from one player to another, deleting the events from the source player. NB: Although partial bars can be moved from the source player, the entire bars of the target players are always overwritten, resulting in rests in those segments of the target players' bars that do not contain the moved material. This method thus best lends itself to moving into target players parts that have rests in the corresponding bars.
ARGUMENTS
- A slippery-chicken object. - The ID of the source player. - The ID of the target player. - A number that is the first bar from which events are to be moved. - A number that is the first event within the start-bar that is to be moved. - A number that is the last bar from which events are to be moved. - A number that is the last event within the end-bar that is to be moved.
OPTIONAL ARGUMENTS
keyword arguments: - :transposition. A positive or negative number that is the number of semitones by which the copied material is to be first transposed. This number can be a decimal number, in which case the resulting pitches will be rounded to the nearest microtone (if the current tuning environment is capable of microtones). - :consolidate-rests. T or NIL to indicate whether resulting consecutive rests should be consolidated each into one longer rest. T = consolidate. Default = T.
RETURN VALUE
Returns T.

DESCRIPTION
Transpose fast repeated notes by given intervals, typically, as in piano music, by an octave. Note that if there are several fast repeated notes then there will be multiple transpositions e.g. (c4 c4 c4 c4 c4) would become by default (c4 c5 c4 c5 c4).
ARGUMENTS
- the slippery-chicken object - the player (symbol) or players (list) to process
OPTIONAL ARGUMENTS
keyword arguments: - :start-bar. The bar to start processing at (integer). Default = 1. - :end-bar. The bar to stop processing at (inclusive). Default = NIL = last bar of the piece. - :intervals. A list of semitone intervals. Default = '(12) = only transpose up one octave. A list of any length may be used for variation; it will be used cyclically. - :threshold. The maximum time difference in seconds between events that will result in the 'octavisation'. Default = the slippery-chicken object's fast-leap-threshold (0.125 seconds by default). - :verbose. Print bar numbers where processing takes place. Default = NIL. - :whole-chords. T or NIL to transpose whole chords or just the repeated notes in chords (could result in unplayable chords if NIL). Default = T = transpose whole chord. - :check-ties. Whether to call the check-ties method, which as a side-effect makes sure tied notes are of the same pitch. Default = T.
RETURN VALUE

slippery-chicken-edit/orchestrate [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DATE
November 2nd 2018, Heidhausen
DESCRIPTION
'Orchestrate' the chords and single pitches in an existing slippery-chicken object. This involves mapping the existing players' pitch events onto a group of new players (a 'combo'). The procedure is fairly complex and by no means perfect (in fact it may exit with an error, especially if your requirements are :strict (see below)), but it works like this: First, we assume that your existing music is more vertical/harmonic than horizontal/linear/melodic, particularly because the mapping process treats each chord separately and potentially maps each chord onto different players---the choice of whether to change ensemble is decided by an activity-levels object by default (see :combo-change-fun below) but also by the number of notes in any given chord and whether it's possible to play any subsequent chord on the same instruments. The method also assumes that each 'player' in the existing slippery-chicken object has a sequence of one or more chords which can be separated into 'phrases' using the get-phrases method; that the new ensemble uses player IDs that don't exist in the original ensemble (though any player can use the same instruments, of course); and that using the player IDs from the new ensemble we provide lists of sublists of possible 'combos' that should be used to play the existing chords. These combos should range from 2 players to however many we'll need to play the existing chords. We pass these combos to the method and/or allow them to be created by the 'lotsa-combos' ensemble method (see :combos below) Whether a chord is playable by a given combo is determined by the range of the chord and the instruments of any given combo, along with those instruments' abilities to play chords and/or microtones (if the chord is microtonal). When trying to determine whether a given combo can play a chord, we permutate the possible instrument orderings to see if the pitches are in range. If :artificial-harmonics is T we also try for such on notes normally considered too high for any given string instrument. If we can't find a combo for any given chord we'll keep track of the best match and if our :relax argument allows, use that instead of backing out completely. One of the complexities we face, after determining that a chord is playable by a particular combo, is whether the players are free (i.e. not already playing) at the time the chord needs to be played. We take ties into account of course, but one limitiation, presently, is that in order be deemed 'free' each instrument of the combo must have a complete bar free for the start and end of any given chord. As we select the current instrument using the instrument-change-map slot of the slippery-chicken object (which may have been changed after the original data was generated) this method works with players who double on two or more instruments. NB If all goes well, each note in a chord will be played by one instrument. Of course orchestration often involves 'doubling' where each note is played by more than one instrument. To achieve this, call orchestrate multiple times, perhaps increasing the :relax value on subsequent calls so that the method doesn't exit when it can't find a 2nd, 3rd, or 4th (...) combo to play a given chord.
ARGUMENTS
- the slippery-chicken object whose existing players and event data will be used to orchestrate onto new players - a new ensemble, the players/instruments of which will be used for the new orchestration. (This shouldn't be a nested ensemble but that's a rarity.) This can either be an ensemble object or a list structure that can be made into one (as used for most calls to make-slippery-chicken). - a list of player IDs indicating the original music to be re-orchestrated.
OPTIONAL ARGUMENTS
keyword arguments: - :combos. A list of lists indicating the player groupings to be used to orchestrate the events. Default = NIL whereupon the <new-ensemble> will be used to generate groupings via the 'lotsa-combos' ensemble class method. - :add-more-combos. T or NIL to indicate whether the :combos slot should be expanded via the 'lotsa-combos' method. If T then whatever is passed to :combos will nevertheless be retained after the expansion. Default = NIL. - :sub-combos. T or NIL to indicate whether the :combos slot should be expanded via the sub-groups function. This is quite different to :add-more-combos as that approach uses permutations of all the instruments in the ensemble whereas this approach uses permutations of sub-sets of the given :combos (only) instead. - :start-bar. The bar number to start orchestrating. Default = NIL which will in turn default to 1 - :end-bar. The bar number to stop orchestrating (inclusive). Default = NIL which will in turn default to the last bar of the slippery-chicken object. - :auto-beam. T or NIL to indicate whether to call auto-beam in the new parts. Default = T. - :chords. Whether individual instruments capable of playing chords should attempt to do so. This may determine whether a given combo is determined to be capable of playing one of the original slippery-chicken object's chords, and also whether under some circumstances some notes will be doubled across different instruments. Default = T. - :combo-change-fun. A function which should return T or NIL to indicate whether we should change combo on any given event. This should take two arguments (the combo as a list of player IDs and an assoc-list of all possible combos (as created by the organise-combos method using the <combos> argument given here) plus two further optional arguments which are free to define. The function should also provide "reset" functionality or do nothing if one of the two required arguments is NIL. Default = combo-change? (defined in event.lsp). - :verbose. T or NIL to turn on the printing of orchestration decisions as the algorithm is run. - :artificial-harmonics. T or NIL to allow the selection of string artificial harmonics in order to reach high notes outwith normal ranges. - :sticky-stats. T or NIL to indicate whether the statistics collected and returned by the method should be reset or retained between calls. Default = NIL = reset. - :relax. An integer between 0 and 3 inclusive to indicate how strict the algorithm should when allocating chord pitches to instruments. The values have the following meanings with degrees of relaxedness ascending: 0: each pitch in the chord has to be playable by at least one instrument in the combo; no instrument can sit this chord out but instruments can play chords that include notes found in other instruments. 1. instruments may sit out a chord if a chord-playing instrument can fill in the notes (all notes of chord must still be played) 2. notes can be left out and instruments can sit out a chord 3. whole chords can be left out
RETURN VALUE
Five statistics values representing the number of chords where: 1. all pitches & every player used; 2. all pitches but some players tacit; 3. some pitches and instruments missing; 4. chords completely left out; 5. total chords attempted

slippery-chicken-edit/re-bar [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
Arrange the events of specified consecutive bars in a given slippery-chicken object into new bars of a different time signature. If the number of beats in the specified series of events does not fit evenly into full measures of the the specified time signature, the method will do its best to create occasional bars of a different time-signature that are as close as possible to the desired length. This method will only combine existing short bars into longer ones; it won't split up longer bars and recombine them. NB: This method should not be confused with the rebar method (which is used internally, not directly by the user). NB: as this reorganises fundamental structures within the slippery-chicken object, it may cause methods like clm-play to fail with some arguments which seem reasonable to the user. So use immediately before creating the score and after creating other outputs.
ARGUMENTS
- A slippery-chicken object.

keyword arguments - :start-bar. An integer that is the number of the first bar whose events are to be re-barred. - :end-bar. An integer that is the number of the last bar whose events are to be re-barred. - :min-time-sig. A time signature in the form of a 2-item list containing the number of beats and the beat unit; e.g. '(3 4). This is a target time signature from which the method may occasionally deviate if the number of events does not fit evenly into full bars of the specified time signature. - :verbose. T or NIL to indicate whether to print feedback on the re-barring process to the Listener. T = print feedback. Default = NIL. - :check-ties. T or NIL to indicate whether to force the method to ensure that all ties have a beginning and ending. T = check. Default = T. - :auto-beam. T, NIL, or an integer. If T, the method will automatically attach beam indications to the corresponding events according to the beat unit of the time signature. If an integer, the method will beam in accordance with a beat unit that is equal to that integer. If NIL, the method will not automatically place beams. Default = T. - :update-slots. T or NIL to indicate whether to update all slots of the given slippery-chicken object after applying the method. This is an internal argument and will generally not be needed by the user.
RETURN VALUE
Returns T.

slippery-chicken-edit/replace-events [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
Replace one or more consecutive existing event objects with new event objects. All references are 1-based. This method can be applied to only one bar at a time. One or more new event objects can be specified as a replacement for one single original event object. It's the user's responsibility to make sure the bar is full and update-slots is called after all post-generation editing.
ARGUMENTS
- A slippery-chicken object. - The ID of the player whose part is to be modified. - An integer that is the number of the bar in which the change is to be made; or a reference to the bar in the format '(section sequence bar). - An integer that is the number of the first event object in the given bar to replace. - An integer that is the total number of consecutive original event objects to replace. - A list of the new event objects, each in turn specified as a 2-item list in the format (pitch rhythm), e.g. '((c4 e)). Rests are indicated with NIL or 'r, e.g. (nil s) (r h). Chords are indicated by enclosing the pitches of the chord in a list, e.g. ((c4 e4) e).
OPTIONAL ARGUMENTS
- T or NIL to indicate whether to automatically re-beam the given bar after replacing the events. T = beam. Default = NIL. - A list of integers to indicate tuplet bracket placement, in the format '(tuplet-value start-event end-event). These numbers are 0-based and inclusive and count rests.
RETURN VALUE
Returns T.

slippery-chicken-edit/replace-multi-bar-events [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
Replace specified consecutive event objects across several bars. The new rhythms provided must produce full bars for all bars specified; i.e., if only a quarter note is provided as the new event for a 2/4 bar, the method will not automatically fill up the remainder of the bar. In that case you'll get a warning and the procedure will exit. This means if you don't know how many bars you want to replace events for, you can pass a large number and ignore the warning and providing you've filled the bars, all should be well.
ARGUMENTS
- A slippery-chicken object. - The ID of the player whose part is to be modified. - An integer that is the number of the first bar in which event objects are to be replaced. This can be an absolute bar number or a list in the form '(section sequence bar); or with subsections then e.g. '((3 1) 4 2)). - An integer that is the number of bars in which event objects will be replaced. - The list of new event objects. The new event objects can be passed as complete event objects; as a list of 2-item lists that are note-name/rhythm pairs, e.g: '((c4 q) (d4 e)); or as a list with two sub-lists, the first being just the sequence of rhythms and the second being just the sequence of pitches, e.g: '((q e) (c4 d4)). For the latter, :interleaved must be set to NIL. (see :interleaved below). Pitch data is the usual cs4 or (cs4 cd3) for chords, and NIL or 'r indicate a rest. NB: All pitches are sounding pitches; written pitches will be created for transposing instruments where necessary.
OPTIONAL ARGUMENTS
keyword arguments: - :interleaved. T or NIL to indicate whether the new event data is to be processed as a list of note-name/rhythm pairs (or existing event objects), or if it is to be processed as a list with two sub-lists, the first containing the sequence of rhythms and the second containing the sequence of pitches (see above). T = interleaved, i.e. already existing event objects or a list of note-name/rhythm pairs. NIL = separate lists for rhythms and pitches. Default = T. If this argument is T, the list of 2-element lists (note-name/rhythm pairs) is passed to make-events, but such a list can contain no ties. If the argument is set to NIL, the rhythm and pitch data is passed as two separate lists to make-events2 where + can be used to indicate ties. - :consolidate-rests. T or NIL to indicate whether shorter rests should automatically be consolidated into a single longer rest. T = consolidate. Default = T. NB: slippery chicken will always consolidate full bars of rest into measure-rests, regardless of the value of this argument. - :beat. NIL or an integer (rhythm symbol) that indicates which beat basis will be used when consolidating rests. If NIL, the beat of the time signature will be used (e.g. quarter in 4/4). Default = NIL. - :auto-beam. T or NIL to indicate whether to automatically beam the new events. T = automatically beam. Default = T. - :tuplet-bracket. NIL or an integer to indicate whether to automatically add tuplet (e.g. triplet/quintuplet) brackets to the new events where applicable. If this is an integer, all tuplets in the given bar will be given a tuplet bracket with that integer as the tuplet number. NB: This option does not allow for setting tuplets of different numbers for the same bar. To do that, set :tuplet-bracket to NIL and add the tuplet-brackets manually. NIL = place no brackets. Default = NIL.
RETURN VALUE
The number of new events used to replace the old ones.

[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
Pass through the entire given slippery-chicken object and change some of the pitch objects to their enharmonic equivalents to produce more sensible spellings of consecutive pitches in the score. An optional argument takes a list specifying which pitches to change in the same format found in the method enharmonic-spellings; i.e. '((player (bar note-num))). These notes are changed after the respelling routine has run. NB: If a list of corrections is specified, the :respell-notes argument of any subsequent call to cmn-display or write-lp-data-for-all must be set NIL, otherwise the modified pitches may be overwritten. Also, although this algorithm corrects tied notes when respelling, notes referenced in the corrections list will not be followed through to any subsequent ties.
ARGUMENTS
- A slippery-chicken object.
OPTIONAL ARGUMENTS
- A list of specific notes whose pitches are to be enharmonically flipped, in the format, e.g. '((vn (1 1) (1 4)) (vc (2 3) (3 3)))
RETURN VALUE

[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
Pass through the pitches of a specified player's part and change some of the pitches to their enharmonic equivalents in order to produce more sensible spellings of consecutive notes. This is just a very simple attempt to better spell notes by comparing each note to the previous two and making it the same accidental type. It doesn't look further back or ahead as of yet. If the optional argument is set to T, then look at the written notes instead of the sounding notes. NB: Since both the cmn-display and write-lp-data-for-all methods automatically call respell-notes for all players of an entire sc-object, their :respell-notes argument may need to be set to NIL for this method to produce the desired results.
ARGUMENTS
- A slippery-chicken object. - The ID of the player whose pitches are to be modified.
OPTIONAL ARGUMENTS
- T or NIL to indicate whether to change written pitches only or sounding pitches only. T = change written pitches only. Default = NIL.
RETURN VALUE
Returns NIL.

[ Top ] [ slippery-chicken-edit ] [ Methods ]
DATE
April 23rd 2016, Edinburgh
DESCRIPTION
Sometimes, even pitch curves without repeated notes result in repeated notes in the generated piece. Often it's the removal of large fast leaps in instrumental parts that ends up creating repeated notes. This method will do its best to replace repeated notes, even in chords, with other notes from the current set and within the range of the current instrument and any set-limits. If a chord is required, then the current instrument's chord function will be used to create the replacement chord.

DESCRIPTION
Remove the specified slurs from the MARKS slots of specified events in the parts of specified players. If the <players> argument is set to NIL, remove the specified slurs from all players.
ARGUMENTS
- A slippery-chicken object. - An integer or a 2-item list of integers indicating the first bar and note from which to remove slurs. If an integer, this is the bar number and the slurs will be removed from all notes in the bar. If a 2-item list, this is a reference to the bar number and number of the first note in the bar from which to start removing slurs, in the form e.g. '(3 1). - An integer or a 2-item list of integers indicating the last bar and note from which to remove slurs. If an integer, this is the bar number and the slurs will be removed from all notes in the bar. If this is a 2-item list, this is a reference to the bar number and number of the first note in the bar from which to start removing slurs, in the form e.g. '(3 1). - The ID or a list of IDs of the players from whose parts the marks are to be removed.

DESCRIPTION
For the given bars and players, round the events' pitch data to the nearest in the current or given scale. For example, a slippery-chicken object could be generated in the :quarter-tone scale, then the scale changed to :chromatic (or the keyword argument :scale 'chromatic-scale given), this method then called, and all pitches would be rounded to the nearest chromatic pitch. See the pitch class method for more details.
ARGUMENTS
the slippery-chicken argument
OPTIONAL ARGUMENTS
keyword arguments: - :start-bar. A number that is the first bar which should be processed. Default = NIL in which case 1 will be used. - :end-bar. A number that is the last bar which should be processed. Default = NIL in which case all bars will be processed. - :players. A list of the IDs of the players to whose parts the function should be applied. Can also be a single symbol. If NIL then all players will be processed. - :scale. The scale to use when rounding. (Common Music tuning object or symbol). If a symbol, then 'chromatic-scale, 'twelfth-tone, or 'quarter-tone only at present. Default is the current scale as set by (in-scale :...).

slippery-chicken-edit/sc-delete-beams [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
Delete beam indications from specified notes. If only a bar number is
specified, this method deletes all beams in the bar.
NB: If specifying start and end notes, the start notes specified must be
the first note of a beamed group of notes (i.e. the BEAMS slot of the
corresponding event object must be 1), and the end note must be the
last note of a beamed group of notes (i.e., the BEAMS slot of the
corresponding event object must be 0), otherwise errors may
occur. Also, if specifying one of these arguments, both must be
specified.
ARGUMENTS
- A slippery-chicken object. - An integer that is the number of the bar in which the beams are to be deleted. - The ID of the player from whose part the beams are to be deleted.
OPTIONAL ARGUMENTS
- An integer that is the number of the note that currently holds the start-beam information (i.e., the BEAMS slot is 1). This number is 1-based and counts ties. - An integer that is the number of the note that currently holds the end-beam information (i.e., the BEAMS slot is 0). This number is 1-based and counts ties.
RETURN VALUE
If deleting all beams in a bar, returns T, otherwise returns NIL.

DESCRIPTION
Change the specified event object to a rest. If events tied from this event should automatically be forced to rests also, use the sc-force-rest2 method instead.
ARGUMENTS
- A slippery-chicken object. - An integer that is the number of the bar in which the rest is to be forced. - An integer that is the number of the event within that bar which is to be changed into a rest. This number is 1-based and counts tied notes but not rests. - The ID of the player whose part is to be modified.
OPTIONAL ARGUMENTS
- T or NIL to indicate whether the specified bar should be automatically beamed after the change has been made. NB: In general, calling auto-beam is a good idea (esp. when deleting notes under an existing beam); however, auto-beam may fail when addressing bars that contain notes longer than one beat. T = automatically beam. Default = NIL.
RETURN VALUE

DESCRIPTION
Turn events into rests, doing the same with any following tied events. NB As it is foreseen that this method may be called many times iteratively, there is no call to check-ties, auto-beam, consolidate-rests, or update-instrument-slots (for statistics)--it is advised that these methods are called once the last call to this method has been made. gen-stats is however called for each affected bar, so the number of rests vs. notes should be consistent with the new data. NB This fill trigger an error if attempted with grace-notes
ARGUMENTS
- A slippery-chicken object - The bar number (integer) - The event number in the bar (integer, counting from 1) - The player name (symbol)
OPTIONAL ARGUMENTS
- T or NIL to delete all marks when a note is turned into a rest. Default = NIL. - A function object to be called on error (could be #'error (default), #'warn, #'print or simply NIL for no error)
RETURN VALUE
The number of events turned into rests.

slippery-chicken-edit/set-cautionary-accidental [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DATE
28-Sep-2011
DESCRIPTION
A post-generation editing method: Place a cautionary accidental
(sharp/flat/natural sign in parentheses) before a specified note.
NB: Adding cautionary accidentals to pitches within chords is currently
only possible in LilyPond output. Adding cautionary accidentals to
single pitches is possible in both CMN and LilyPond.
NB: Since the cmn-display and write-lp-data-for-all methods call
respell-notes by default, that option must be explicitly set to NIL
within the calls to those methods in order for this method to be
effective.
ARGUMENTS
- A slippery-chicken object. - An integer that is the number of the bar in which to add the cautionary accidental. - An integer or a 2-item list of integers that is the number of the note within that bar to which to add the cautionary accidental. This number is 1-based and counts ties. If a 2-item list such, this indicates that the pitch is within a chord; e.g., '(1 2) indicates that a cautionary accidental should be added to the 2nd pitch up from the bottom of the chord located at the 1st note position in the bar. - The ID of the player to whose part the cautionary accidental is to be added.
OPTIONAL ARGUMENTS
- T or NIL to indicate whether to add the cautionary accidental to only the written pitch or only the sounding pitch. T = written only. Default = NIL.
RETURN VALUE
Returns T.

DATE
February 20th 2018, Heidhausen
DESCRIPTION
For each section/subsection of a piece, set the highest or lowest pitch, i.e. create the curve for one player in the set-limits-high or set-limits-low slot. N.B.1 As well as returning the generated list, the respective slot value (<which>) is also changed. N.B.2 As the internal structure of the slippery-chicken object is modified here, and this has implications for pitch-selection, i.e. constraints for an already-existing slippery-chicken object (made, probably, by make-slippery-chicken), the piece will have to be regenerated by explicitly calling (sc-init) after calling this method.
ARGUMENTS
- the slippery-chicken object - the pitches: a list of pitch symbols or MIDI note numbers. Note that these will be used cyclically if there aren't enough pitches for the number of sections/subsections in the piece. - 'set-limits-high or 'set-limits-low to set the desired curve
OPTIONAL ARGUMENTS
- which player (symbol) to set the curve for. Default = 'all, which means the curve will apply to all players.
RETURN VALUE
The curve created (list)

[ Top ] [ slippery-chicken-edit ] [ Methods ]
DATE
October 25th 2018, Heidhausen
DESCRIPTION
Change the midi-channels of events in the slippery-chicken object. All events' pitch objects' midi-channel slots will be destructively overwritten when using this method. The second argument is a list of lists. Each sublist has the player (not instrument) ID symbol as its first element, followed by one or two channel numbers. If only one channel is given (i.e. it's a two-element list e.g. (vln 1)) then it will be used for both chromatic and microtonal pitches (i.e. all the players' pitches will be written to the one given midi channel). Otherwise if a second channel is given (e.g. (vln 1 2)) then microtonal pitches will be written on the second channel.
ARGUMENTS
- the slippery-chicken object. - a list of player and channel info (see above and example below).
OPTIONAL ARGUMENTS
- the start-bar in which events should begin to be processed. Default = 1 - the end bar (inclusive) in which the last events should be processed. Default = NIL = the last bar of the slippery-chicken object.
RETURN VALUE

DESCRIPTION
Add the specified rehearsal letter/number to the specified bar in one or more specified players. NB: Since internally this method actually attaches the rehearsal letter/number to the REHEARSAL-LETTER slot of the preceding bar (bar-num - 1), no rehearsal letter/number can be attached to the first bar.
ARGUMENTS
- A slippery-chicken object. - An integer that is the number of the bar to which the rehearsal letter/number is to be added. - A symbol that is the rehearsal letter/number to be added (e.g. 'A or '1)
OPTIONAL ARGUMENTS
- The player ID or a list of player IDs to whose parts the rehearsal letter/number is to be added. If no value is given here, the rehearsal letter/number will be added to the first (top) instrument in each group of the ensemble, as specified in staff-groupings.
RETURN VALUE

slippery-chicken-edit/thin [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DATE
19th September 2018, Heidhausen
DESCRIPTION
Thin out events in a slippery-chicken object using an activity curve. This turns existing notes into rests. As this is an expensive method but may be called more than once, it is up to the user to call consolidate-rests and/or update-slots when ready.
ARGUMENTS
- the (fully-initialised) slippery-chicken object
OPTIONAL ARGUMENTS
keyword arguments - :start-bar. The bar to start at. Default = NIL = 1 - :end-bar. The bar to end at. Default = NIL = last bar in piece/object - :players. A symbol or list of symbols for the players to be processed. - :curve. A list of breakpoints representing the level of activity. Y-values should range over 0 (all events forced to rests) to 10 (no rests created). X-values may range over any arbitrary scale but NB that this will be rescaled to map over the number of bars in the whole piece, despite the start-bar/end-bar arguments. However this rescaling can be avoided via the next argument. Default = '(0 1 100 10) - :rescale-curve. Whether to process the x-values of :curve to range over the number of bars in the piece. Default = T = rescale.
RETURN VALUE
- the processed slippery-chicken object

slippery-chicken-edit/tie [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
Add a tie to a specified event object. The new tie will be placed starting from the specified event object and spanning to the next event object. If the next event object does not have the same pitch, its pitch will be changed to that of the first event object. An optional argument allows the user to adjust the steepness of the tie's curvature. NB: This method will not automatically update ties in MIDI output. To make sure that MIDI ties are also updated, use the handle-ties method. NB: If the next event object is a rest and not a note, an error will be produced.
ARGUMENTS
- A slippery-chicken object. - An integer that is the number of the bar in which the tie is to be placed. - An integer that is the number of the note to which the tie is to be attached. - The ID of the player whose part is to be changed.
OPTIONAL ARGUMENTS
- A positive or negative decimal number to indicate the steepness of the tie's curvature.
RETURN VALUE
Returns T.

slippery-chicken-edit/tie-all-last-notes-over-rests [ Methods ]
[ Top ] [ slippery-chicken-edit ] [ Methods ]
DESCRIPTION
Extend the duration of the last note of any bar that precedes a bar which
starts with a rest in the specified region, such that the rest that begins
the next measure is changed to a note and the last note of the first
measure is tied to it.
NB: This method will not automatically update ties in MIDI output. To make
sure that MIDI ties are also updated, use the handle-ties method.
ARGUMENTS
- A slippery-chicken object. - An integer that is the first bar in which changes are to be made. - An integer that is the last bar in which changes are to be made. - A player ID or list of player IDs.
OPTIONAL ARGUMENTS
keyword arguments: - :to-next-attack. T or NIL to indicate whether ties are to extend over only full bars of rest or also over partial bars (until the next attacked note). T = until the next attacked note. Default = T. - :tie-next-attack. T or NIL to indicate whether the new tied notes created should also be further extended over the next attacked note if that note has the same pitch as the starting note of the tie. T = also tie next attacked note if same pitch. Default = NIL. - :auto-beam. T or NIL to indicate whether the new events should be automatically beamed after placement. T = automatically beam. Default = NIL. - :last-rhythm. NIL or a rhythmic duration. If a rhythmic duration, the last duration of the tie will be forced to this length. Useful, for example, when tying into a rest bar without filling that whole bar. NIL = fill the bar with a tied note. Default = NIL. - :update. T or NIL to indicate whether all slots for all events in the piece should be updated. This is an expensive operation so set to NIL if you plan on calling other similar methds, and call (update-slots sc) explicitly at the end. Default = T.
RETURN VALUE
Returns NIL.

keyword arguments: - :start-note. An integer that is the number of the first attacked note (not counting rests) in the given start-bar for which ties can be placed. - :end-note. An integer that is the number of the last attacked note (not counting rests) in the given end-bar for which ties can be placed. NB: This argument does not necessarily indicate the note on which the ties will stop, but rather the last not on which a tie can begin; the ties created may extend to the next note. - :auto-beam. T or NIL to indicate whether the method should automatically place beams for the notes of the affected measure after the ties over rests have been created. T = automatically beam. Default = NIL. - :consolidate-notes. T or NIL to indicate whether the tied note are to be consolidated into single rhythmic units of longer durations after the ties over rests have been created. T = consolidate notes. Default = NIL. - :update. T or NIL to indicate whether all slots for all events in the piece should be updated.

A post-generation editing method: Remove the parentheses from a cautionary accidental (leaving the accidental itself) by setting the ACCIDENTAL-IN-PARENTHESES slot of the contained pitch object to NIL. NB: Since respell-notes is called by default within cmn-display and write-lp-data-for-all, that option must be explicitly set to NIL for this method to be effective.
ARGUMENTS
- A slippery-chicken object. - An integer that is the number of the bar in which the cautionary accidental is to be unset. - An integer that is the number of the note in that bar for which the cautionary accidental is to be unset. - The ID of the player whose part is to be changed.
OPTIONAL ARGUMENTS
- T or NIL to indicate whether to unset the cautionary accidental for the written part only (for transposing instruments). T = written only. Default = NIL.
