Re: [TeX-music] pmx: note-slur-pause

2002-07-15 Thread Hiroaki MORIMOTO 

Hello Don, Alexandros, and all,

This is a bit out-of-date topic: combination of note-slur-pause.

Following does not work well on PMX(2.30-)2.402 with and without `Ap'.
Slurs are parsed, horizontal positioning is *OK*, but the vertical 
position of end is always {b}.

1 1 4 4 4 4  0 0 0 4 20 0

0
./
Ap
c25d s r4 s /

c24d s r4 s /


In these cases, slurs should be level at default.
Don, Would you please fix this?

Also, a combination of note-slur-pause is sometimes seen in songs
and tunes for pianoforte.
This says to a singer that the note must be sustained `espressivo'
during the note length.
This is quite different expression from a tenuto but it's hard 
to explain in letters. 
Anyway a combination of note-slur-pause makes important musical sense.


By the way, not only my package but perhaps also Stanislav's package
has no limit with slur slope.
How about abolishing the slur slope limitter shown below?

[TeX-music] absolute octave number through M-Tx

2002-07-15 Thread Hiroaki MORIMOTO 

Hello Dirk and all,

In the M-Tx user's guide, section B.4:

> Octave is inserted into the first note of each voice, depending 
> on the clef. Absolute octave numbers are not recognized by M-Tx 
> and may cause unexpected side effects.

I have a proposal to reject the side effect (surplus octave assignment).


mtx.c (in mtx052_patch.zip), line 168-169: 
( in function "void checkOctave()" ) 

current:

  if (octave(voice) == blank)
return;


proposal:

  if (octave(voice) == blank)
return;
  else if ( isdigit(note[1]) ? isdigit(note[2]) : isdigit(note[3]) ){
resetOctave(voice);
return;
  }



I think this patch keeps compatibility with current M-Tx syntax,
but I'm not sure.  Tests in many cases are required.


By the way, the C source of M-Tx seems to be dependent on gcc.
I tried compiling M-Tx with MS-VC++6.0(x86)-SP3 on Win2000 
in ANSI-C compatible, no optimazation mode (cl /Od /Za /c *.c), 
but many warnings appeard and the resulting executable is 
somewhat unstable (large .mtx input leads to crush), 
both with and without this change.

cygwin-b20 (egcs-2.91.57) on Win2000 seems OK.
