       autosp - preprocessor to generate note-spacing commands for MusiXTeX scores


       autosp [-v | --version | -h | --help]

       autosp [-d | --dotted] [-l | --log] infile[.aspc] [outfile[.tex]]

       This  program  makes  it  easier  to  create  MusiXTeX scores by converting (non-standard)
       commands of the form \anotes ... \en into one or more conventional  note-spacing  commands
       (\notes  \Notes  \NOtes  ...),  determined  by  the  actual  note values, with \sk spacing
       commands inserted as necessary.  The coding for an entire measure can be entered one  part
       at  a  time,  without  concern  for  note-spacing  changes  within  the  part  or  spacing
       requirements of other parts.

       For example, if applied to

           \anotes\qa J\qa K&\ca l\qa m\ca n\en

       autosp generates

           \Notes\qa J\sk\qa K\sk&\ca l\qa m\sk\ca n\en

       Typically, an \anotes command generates several conventional note-spacing commands.

       If the infile argument does not have an .aspc extension, input is taken  from  infile.aspc
       if that file exists.

       If the outfile argument does not have a .tex extension, output is sent to outfile.tex.  If
       no outfile argument is provided, output will go to  infile.tex  (or  to  infile.ltx  if  a
       \documentclass declaration is encountered).

       For  \anotes  commands,  line  breaks  and spaces may precede note segments, allowing more
       flexible source formatting; the line breaks and spaces will be elided from the output.

       For example,


       is acceptable and generates


       If the -l ( --log ) option is used, a very detailed log infile.alog is generated.

       If the -d ( --dotted ) option is used, dotted beam notes of the form  \qb{n}{.p}  are  not
       given  extra space; it is assumed that the subsequent note will be shifted by a \roff-like
       command or a spacing command such as  \qsk  or  \hqsk.   Commands  of  the  form  \qlp{p},
       \qlpp{p}, ..., \qpb{n}{p} and \qppb{n}{p} are always spaced as indicated.

       If  there  is  a single staff, consecutive whole-bar rest bars are merged into a multi-bar
       rest. Bar-centered rests can be coded using the standard \def\atnextbar notation  but  the
       non-standard command \Cpause in a note segment also generates a bar-centered rest.

       Spacing  commands  \sk  and  \bsk in the source are discarded, but not "small" skips \hsk,
       \qsk, \tqsk, \hqsk or \qqsk, or the small "backward" skips \hbsk, \bqsk, \btsk, or  \bhsk.
       Moreover,  non-standard  commands  \QQsk,  \HQsk  \TQsk  and  \Qsk  in the source generate
       "global" skips; i.e., the effect of \qqsk, \hqsk, \tqsk or \qsk, respectively,   in  every
       staff. These ensure that staffs remain synchronized if additional spacing is needed in any

       Global skips may also be obtained within collective-coding sequences by using up  to  four
       successive commas to get the effects of \QQsk, \HQsk, \TQsk or \Qsk, respectively.  Global
       skips \tqsk (or, for double-flats, \qsk) are  automatically  inserted  before  accidentals
       ('^',  '_',  '=',  '<', '>') on collective-coding notes (except when the preceding note is
       "virtual"; i.e., a skip).  If this automatic additional spacing  is  not  wanted  in  some
       context,  it  may be avoided by replacing the accidental in the collective-coding sequence
       by any of the explicit accidental commands: \sh, \fl, \na, \smallsh, \bigsh, etc.  If  the
       automatic  spacing  is  insufficient,  the  spacing  may be increased by adding sufficient
       commas or using a conventional notes command instead of \anotes.

       A note segment can be completely empty, but if a note segment should start with or contain
       a  "space,"  the note-value of that space must be made explicit with a command of the form
       \ha{*}, \qa{.*}, \qa{*}, \ca{*}, etc.

       From version 2017-06-14, the effects of  \TransformNotes  calls  are  implemented  by  the
       autosp  pre-processor.  This  enables  use  of  musixlyr in autosp scores; musixlyr.tex is
       incompatible with the musixtnt.tex implementation of \TransformNotes.

       All other conventional MusiXTeX commands are output exactly as given in the input.


       autosp determines the spacing for ordinary notes from the note  commands  themselves;  for

       +  \qa, \qu, \ql, \qp result in \NOtes;

       +  \ca, \cu, \cl, \ds result in \Notes;

       and so on.

       The  spacing  for  beamed  notes  is  determined  by the beam multiplicity, so that \ib...
       results in \Notes, \ibb... results in \notes, etc.

       Collective coding of note  sequences  (including  accidentals  and  dots)  is  handled  by
       expanding the sequence into a sequence of individual note commands.


       autosp  assumes  that  &  and  |  (rather than \nextinstrument and \nextstaff) are used to
       separate instruments and staffs.

       Appoggiaturas and grace notes are recognized by the use of \tinynotesize; note-spacing  of
       1.45\elemskip  is used. If this isn't suitable and can't be corrected with a small skip, a
       \vnotes command with any desired spacing can be used.

       autosp supports x-tuplets introduced using  \xtuplet{x}  or  \xxtuplet{x:y}  and  triplets
       introduced using any of the following commands (regardless of any re-definition of \txt or


       autosp assumes that an x-tuplet is to be  played  in  (x-1)/x  of  the  apparent  x-tuplet
       duration.   So,  for  example, a triplet in eighths is assumed to be played in the time of
       one quarter note.  If this assumption isn't valid, the x-tuplet must be  coded  explicitly
       using a suitable \vnotes command; see the first measure of barsant2.aspc for an example of
       a non-standard x-tuplet: a 5-tuple of 64th notes with an intended duration of six 64ths.

       In some polyrhythmic scores, the  \txt  numeral  may  be  displaced,  even  if  the  notes
       themselves  are  correctly  spaced.  In these cases, it is possible to suppress the normal
       output of \txt by using the non-standard commands \Triolet (no arguments) or  \Xtuplet{k}\
       and placing a numeral at the correct location using \zcn (i.e., \zcharnote).

       autosp  can  deal with simultaneous x-tuplets in multiple staffs provided the x values and
       total note durations are identical.

       In some baroque scores, particularly by J.S. Bach, a beamed sixteenth note  is  vertically
       aligned  with  the third note of a triplet of eighth notes in another staff (implying that
       they should be sounded simultaneously); e.g.,


       would be played as if notated

           \uptrio{b}10\ql L\hroff{\cl L}

       The following coding will align the beamed sixteenth note with the third note of a triplet
       in another staff:


       and, similarly, for triplets of sixteenth notes:


       Generally,  user-defined macros are not processed or expanded; however, definitions of the

           \def\atnextbar{\znotes ... \en}

       generate definitions that do take account of \TransformNotes.

       All staffs are assumed to have the same meter; see kinder2.aspc for an example of  how  to
       work around this.

       autosp may not be effective for music with more than one voice in a single staff. It might
       be advisable to use a separate staff for each voice, to avoid \anotes when  necessary,  or
       to omit certain voices initially and add them into the resulting TeX file.


       See  files  quod2.aspc, kinder2.aspc, geminiani.aspc and barsant2.aspc for scores suitable
       for input to autosp.  The program tex2aspc can be used to convert "legacy" MusiXTeX scores
       to .aspc format.
