Readme for PMX beta vs 2.3

Changes from PMX 2.3 to PMX 2.4, 29 June 2002

2.301

2.302

Toggle vshrink with "Av". vshrink normally kicks in when \interstaff hits 20. This still needs work.
Add " /" to last line if last char is not "%" or "/"; issue warning but do not stop.

2.303

2.304

Shrink stemlength: use "Sx" as option within a note, where x is amount to shorten the stem in \internotes. "Sx:" makes it sticky within the current line of music until turned off in a later note by "S:". Stickiness cannot extend over input block boundaries. Shrinkage is limited to the range .5 to 4 \internotes, in .5-\internote increments.

2.305

2.32

Initialize note level to middle C in case user forgets to set octave.
Dotted xtup notes: Include "d" in the note symbol, after the "x" and number if in the first note of the xtuplet. This will add a dot to the current note and another flag to the following one, and change the spacing to reflect the new rhythm.
Automatic notehead shifting in intervals of a 2nd in chords. This will be disabled for the current chord if any user-defined notehead shifts are entered.
Automatic accidental shifting in chords. PMX will adjust accidental positions according to a prescribed set of rules. This will be disabled for the current chord if any user-defined accidental shifts are entered, unless "A" is entered along with the shift, e.g., "zcsA<.5" . In that case the user-defined shift will be added to the PMX-computed one.
User-defined accidental ordering in chords. If you enter "Ao" in the main note symbol of a chord, then the accidentals in that chord will be posted in the order they come in the source file (starting with the main note), each one as far to the right as it will go without crashing into a notehead, stem, or another accidental.

2.321

Recenter storage of horizontal accidental shifts to permit shifts from -5.25 to 1
Fix bug on ihornb in dodyn(), which gave wrong level for dynamics in lower voice with unbeamed xtups.

2.33

New feature: caesura and breath (fat comma). Input like ornaments, "oc" and "ob" respectively. 2 optional modifiers, a signed integer for vertical shift from default in notehead widths, then a signed number for vertical shift in \internote's. Default positions are on top line for caesura; just above for breath, and horizontally 0.5\noteskip BEYOND the associated note. The latter is different from MusiXTeX's \caesura and \zbreath which are placed 0.5\noteskip before the insertion point.

2.331

2.332

2.34

2.341

2.342

Bugfix to recognize relative octave shift in grace at start of input block.
Bugfix to handle xtups starting with rest and containing both 1- and no-flag black notes
In make2bar, initialize islhgt=0 earlier than before as possible solution to Suse g77 compile problem that I could not reproduce.

2.35 (NEW pmx.tex)

Continuation figure may now have fractional length.
May now mix continuations with other figures. If another figure follow Cont-fig, separate with colon.
If user \setsize's some staves to \smallvalue, PMX now detects that and sets grace note size to \tinynotesize (11-pt font) for those staves
Cautionary accidentals: follow accidental with 'c'.
Bugfix (pmxb) to issue \eject after single-system pages.
Bugfix to set default systems/page to 1 if more than 7 voices.
Increase dimension of mcpitch to 20 (max number of simultaneous chord notes in a single line of music for midi processing).
Change figure font specification when \musicsize=16 to \def\figfont{\eightrm}% (no effect on normal output)

2.352 (NEW pmx.tex)

"Ap" activates postscript slurs by inserting "\input musixps" into TeX file. Please note that you must have downloaded and deployed Stanislav Kneifl's musixps.tex for this to work. If you have modified the curvature (using a third number, after positional tweaks) PMX will approximately translate this into "f","h","H", or "HH". For new scores you may use these letters directly in PMX as options in the slur termination command.
Redefine \titles in pmx.tex, to allow multiline instrument, composer, or title. Data entry for each item must still be on one line, but "\\" will cause a line break in the printed score.
Removed redefinition of \parskip from pmx.tex. Now PMX will insert the redefinition into [jobname].tex only if "Ae" has been invoked.
PMX numbers slurs from 0 up instead of 11 down, anticipating postscript slurs.
Increase allowable length of jobname to 44 characters.

2.354 (NEW pmx.tex)

When postscript slurs are activated with "Ap", hairpins (crescendo, decrescendo) will be done in postscript. Only operational differences are (a) Start or ending can be tweaked independently vertically and/or horizontally, allowing slanted hairpins; (b) hairpins may cross a line or page break, but start and ending must still be defined within the same input block.
Check for unclosed hairpins at end of input block.
When postscript slurs are activated with "Ap", true ties will result from using "t" instead of "s", "(", or ")" . Ties are flattened compared with slurs, and have slightly different terminations. This syntax is a minor incompatibility with the older usage of "t", but that only differed in a minor detail from "s", and will remain available if "Ap" is not used.
K-0+n to transpose by half step (rather than just change key).
Multibar rests "rm[n]" now allowed when nv>1, but required in all parts.
"Rz" at beginning of an input block will cause the last bar in the prior block to end with a blank bar line.

2.355 (NEW pmx.tex)

Midi-only transposition by octave: IT[+|-][n1][+|-][n2]...[+|-][n(noinst)], n=# of half-steps, restrict to multiples of 12.
Make midi recognize postscript ties.
Correct \ttieforsl in pmx.tex so that it eats 2nd argument properly, using \zcharnote to get octave right.
Allow hairpins to cross input block boundaries.

2.357

Increase dimension for number of literal TeX strings per input block from 52 to 83.
Allow blank rest in middle of xtuplet.
Allow up to 40 pages total.
Bugfix: In unbeamed xtups "n" now properly suppresses bracket.
Bugfix in parsing of "f,h,H,HH" in sslur.

2.357a

2.358

With postscript slurs "Ap", set PMX defaults \Nosluradjust\Notieadjust\nohalfties.
Allow curvature corrections "f","h","H","HH" at start of postscript slur.
Local postscript slur/tie options in slur/tie commands: p[+|-][s|t] for [nos|s]luradjust,[not|t]ieadjust.
Global postscript slur/tie options: Ap[+|-][s|t|h] for [Nos|S]luradjust,[Not|T]ieadjust,[noh|h]alfties.
Allow index on postscript ties "t[index]" or "s[index]t" NOTE! Cannot use same index for slur and tie open at same time.
Bugfix: Corrects error when xtup starts with rest.
Bugfix: Add spacing for ornament ")" as if it were flag.
With "Ap", "st" slurs will become postscript ties.
Non-beamed xtup: option "a" in 1st note or rest of xtup, before "x".
Allow two text dynamics D"x" on same note.
