 Project:          slippery chicken (algorithmic composition)

 Purpose:          Post-generation editing methods for the slippery-chicken
                   class.  NB only include methods here that the user should
                   access (i.e. no -aux methods) as all of these will be
                   automatically listed and linked on a manual page. Also,
                   in order for these links to work we need
                   ****m* slippery-chicken-edit/replace-tempo-map
                    not

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-mark-all-players [ Methods ]

[ Top ] [ slippery-chicken-edit ] [ Methods ]

DESCRIPTION

 Add a specified mark to a specified even 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

;;; Apply the method twice: Once using an integer to attach the mark to the
;;; same event in all players, and once using a list to attach the mark to
;;; different events in the consecutive players. Print the corresponding marks
;;; slots to see the results.

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.

slippery-chicken-edit/add-marks-to-notes [ Methods ]

[ Top ] [ slippery-chicken-edit ] [ Methods ]

DESCRIPTION

 Add the specified mark or marks to a consecutive sequence of multiple notes
 within the given slippery-chicken object.

ARGUMENTS

 - A slippery-chicken object.
 - An integer or a list consisting of two numbers to indicate the start
   bar/note. If this is an integer, all notes in this bar will receive the
   specified mark or marks. If this is a two-number list, the first number
   determines the bar, the second the note within that bar.
 - An integer or a list consisting of two numbers to indicate the end
   bar/note. If this is an integer, all notes in this bar will receive the
   specified mark or marks. If this is a two-number list, the first number
   determines the bar, the second the note within that bar.
 - The ID of the player or players to whose parts the mark or marks should
   be attached. This can be a single symbol or a list.
 - T or NIL to indicate whether the mark should be added to the MARKS slot
   or the MARKS-BEFORE slot of the given events objects.
 - The mark or marks to be added.

RETURN VALUE

 Returns T.

EXAMPLE

;;; This example calls the method twice: Once using the single-integer
;;; indication for full bars, with one instrument and one mark; and once using
;;; the bar/note reference lists for more specific placement, a list of several
;;; players that should all receive the marks, and multiple marks to add.

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.

slippery-chicken-edit/auto-beam [ Methods ]

[ Top ] [ slippery-chicken-edit ] [ Methods ]

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.

RETURN VALUE

 Returns NIL.

slippery-chicken-edit/auto-clefs [ Methods ]

[ 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.

RETURN VALUE

 Returns T

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

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 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.

 Also see the documentation in the bar-holder class for the method of the
 same name. 

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

 - 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.
 - 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.

RETURN VALUE

 If a 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 event 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.

RETURN VALUE

 Returns T

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.
 - 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.
 - The ID of the player whose part is to be changed.

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.

RETURN VALUE

 Returns T.

[ 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.

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.

RETURN VALUE

 Returns T.

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.

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.

ARGUMENTS

 - A slippery-chicken object.

OPTIONAL ARGUMENTS

 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 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.

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.

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.

SYNOPSIS

(defmethod respell-notes ((sc slippery-chicken) &optional corrections)

slippery-chicken-edit/respell-notes-for-player [ Methods ]

[ 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.

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.

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

 The new rthm-seq-bar object.

DESCRIPTION

 Remove all dynamic marks from the MARKS slots of all consecutive event
 objects within a specified region of bars. 

ARGUMENTS

 - A slippery-chicken object.
 - An integer or a list of two integers. If a single integer, this is the
   number of the first bar from which the dynamics will be removed, and all
   dynamics will be removed from the full bar. If this is a list of two
   integers, they are the numbers of the first bar and first note within
   that bar from which the dynamics will be removed, in the form '(bar-num
   note-num). Note numbers are 1-based and count ties but not rests.
 - An integer or a list of two integers. If a single integer, this is the
   number of the last bar from which the dynamics will be removed, and all
   dynamics will be removed from the full bar. If this is a list of two
   integers, they are the numbers of the last bar and last note within that
   bar from which the dynamics will be removed, in the form '(bar-num
   note-num). Note numbers are 1-based and count ties but not rests.
 - A single ID or a list of IDs of the players from whose parts the dynamics
   are to be removed.

slippery-chicken-edit/set-cautionary-accidental [ Methods ]

[ Top ] [ slippery-chicken-edit ] [ Methods ]

DATE

 28-Sep-2011

DESCRIPTION

 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.

slippery-chicken-edit/set-rehearsal-letter [ Methods ]

[ Top ] [ slippery-chicken-edit ] [ Methods ]

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

 Returns T.

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 tieing into a rest bar without filling that whole
   bar. NIL = fill the bar with a tied note. Default = NIL.

RETURN VALUE

 Returns NIL.

slippery-chicken-edit/tie-over-rests [ Methods ]

[ Top ] [ slippery-chicken-edit ] [ Methods ]

DESCRIPTION

 Extend the duration of a specified note that precedes a rest by changing
 the rest to a note with the same pitch and adding a tie between them.

 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 number of the bar in which the note is located. 
 - An integer that is the number of the note within that bar which is to be
   extended. This number is 1-based and also counts already tied notes.
 - The ID of the player whose part is to be modified.

OPTIONAL ARGUMENTS

 keyword arguments
 - :end-bar. An integer that is the number of the last bar into which the
   tie is to extend. This can be helpful if the user wants to tie into only
   the first of several consecutive full-rest bars.
 - :auto-beam. T or NIL to indicate whether the method should automatically
   beam the beats of the modified bars after the ties have been added.
   T = automatically beam. Default = NIL.
 - :consolidate-notes. T or NIL to indicate whether the method should
   consolidate tied notes into single rhythm units of longer duration.
   T = consolidate. Default = T.

RETURN VALUE

 Returns NIL.

slippery-chicken-edit/trill [ Methods ]

[ Top ] [ slippery-chicken-edit ] [ Methods ]

DESCRIPTION

 Attach a trill mark to a specified event object by adding 'BEG-TRILL-A to
 the MARKS-BEFORE slot and TRILL-NOTE with the pitch to the MARKS slot. This
 method requires a specified trill pitch.

 By default trills are set to span from the specified note to the next note,
 though the length of the span can be specified using the optional
 arguments.

 NB: This is a LilyPond-only method and will not affect CMN output.

ARGUMENTS

 - A slippery-chicken object.
 - The player to whose part the trill is to be added.
 - An integer that is the number of the bar in which the trill is to start. 
 - An integer that is the number of the event object in that bar on which
   the trill is to be placed.
 - A note-name symbol that is the pitch of the trill note.

OPTIONAL ARGUMENTS

 - An integer that is the number of the event object on which the trill span
   is to stop.
 - An integer that is the number of the bar in which the trill span is to
   stop. 

RETURN VALUE

 Returns T.

slippery-chicken-edit/unset-cautionary-accidental [ Methods ]

[ Top ] [ slippery-chicken-edit ] [ Methods ]

DESCRIPTION

 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.

RETURN VALUE

 Returns NIL.

slippery-chicken/change-bar-line-type [ Methods ]

[ Top ] [ slippery-chicken ] [ Methods ]

DESCRIPTION

 Change single to double or repeat bar lines and vice-versa.  NB This is a
 score function only, i.e., if you add repeat bar lines these will not (yet) 
 be reflected in playback with MIDI or CLM.

ARGUMENTS

 - the slippery-chicken object
 - the bar number at the end of which you want the bar line to change
 - bar line type: 0 = normal, 1 = double bar, 2 = final double bar, 3 =
   begin repeat, 4 = begin and end repeat, 5 = end repeat 

RETURN VALUE
