       fixmsxpart - corrects note spacing in a single-staff MusiXTeX part

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

       fixmsxpart [-d |	--debug] infile[.tex] [outfile[.tex]]

       Converts	 a  single-staff MusiXTeX part (possibly derived from a	multi-
       instrument score	and as a result	having irregular note  spacing)	 to  a
       single-staff  part  with	 proper	 spacing determined by the notes them-

       If outfile is not specifed, standard output is used.

   Generating a	Single-Instrument Part
       To generate a single-instrument part from  (a  copy  of)	 the  MusiXTeX
       source for a  multi-instrument score, add

	   \input musixtnt

       to the preamble,	set


       and  use	 the  \TransformNotes macro defined in musixtnt.tex to discard
       all but one part.  For example, the following line placed after \start-
       piece  (but  before any note commands) would be appropriate for a four-
       instrument score	(arguments #2, #3, #4, and #5, separated by three &s),
       and will	result in a part for the second	of these (#3):


       Argument	 #1  is	a scaling parameter and	should not be modified.	 It is
       essential that every \znotes, \notes, \Notes, \NOtes, etc.  command  in
       the  score match	the macro  pattern exactly; insufficient (or too many)
       note segments will result in lost text and possibly  compilation	 fail-
       ure;  see msxlint(1).  It is assumed by \TransformNotes that notes com-
       mands are terminated by \en (rather than	\enotes).

       Some additional manual changes to the source will be necessary:

       +  adjustments of \setname1,  \setclef1,	 \setsign1  ,  \setmeter1  and
	  \setstaffs1 commands,	as necessary;

       +  ensuring  that  tempo	and roadmap markings (D.C., Fine, etc.)	are in
	  the appropriate instrument segment;

       Finally,	if the modified	score is compiled and viewed, it may  be  seen
       that  horizontal	 spacing  designed for multiple	instruments often pro-
       duces bad spacing for a single instrument.  This	can be corrected manu-
       ally (and very tediously) but it	is what	fixmsxpart was designed	to fix
       (much more conveniently).

   Correcting Horizontal Spacing Using fixmsxpart
       The \notes \Notes \NOtes	\NOTes...  commands in a part derived  from  a
       multi-instrument	score are unreliable, and so fixmsxpart	determines the
       spacing for ordinary notes by the note commands themselves;  for	 exam-

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

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

       and  so	on.   Spacing commands \sk and \hsk in the input are discarded
       (but \qsk, \hqsk	and explicit uses of \off{...} are preserved).

       fixmsxpart determines the spacing for beamed notes by the  beam	multi-
       plicity:	\ib... results in \Notes, \ibb... results in \notes, etc. Some
       beam-termination	commands (\tb...) are problematic because the  immedi-
       ately-following	beam note \qb... must be spaced	according to the spac-
       ing before the \tb... command. This is handled by  setting  a  variable
       new_beaming  when processing the	\tb... command and only	updating beam-
       ing to new_beaming when processing  the	subsequent  beam  note.	  This
       isn't  needed  for  the abbreviations \tqb, \tqh, \ztqb and \ztqh which
       combine beam-termination	and specification of the final beam note.

       Pointed notes are not given extra space automatically. They  should  be
       given  extra  space  manually in	the score by using either a \roff-like
       command on the subsequent note or the \qsk or \hqsk spacing commands.

       Additional features of fixmsxpart transformation:

       +  Successive whole-bar rests are accumulated into  a  multi-bar	 rest,
	  with appropriate adjustment of the bar number.

       +  \alaligne and	\alapage commands are replaced by \bar.

       +  \mulooseness,	 \eject,  \linegoal, \song{top | bottom}, \group{top |
	  bottom} and \akkoladen commands are commented	out.

       +  \instrumentnumber...	commands become	\instrumentnumber1.

       +  \nostartrule is added	to the preamble.

       +  Simple slurs or ties initiated by \slur or \tie  are	normalized  by
	  setting  the	n  parameter  to 1 on the assumption that the new note
	  spacing is correct.

       Only single-staff instrumental parts are	supported. User-defined	macros
       are  not	 expanded.  A few esoteric MusiXTeX commands and constructions
       are not supported.
