Changes from PMX 2.4 to PMX 2.5

2.401

• Suboption for Type K postscript ties, activated by Apl, to (a) change first part of a linebreak ties to have same shape as normal ties, and (b) move start of second part of linebreak ties a little to the left.
• Bugfix: Enable arpeggios on chords in xtuplets.

2.402

• Automatic forced beam patterns. If the option ":" (colon) is included in the starting symbol "[" for a forced beam, then henceforth beams of the same length will be forced in that line of music, until stopped. Stop them by either (a) inserting a regular forced beam, or (b) coming to the end of the input block.
• The number of forced beams allowed is increased from 20 to 40 per line of per input block. This includes both regular and the new automatic ones.

2.403

• Bugfix: Automatic termination of auto forced beam patterns at end of input block.

2.404

• Allow slur or tie to end on rest, but not start on a rest. Default height of ending is default height of start (before any automatic or user- defined djustments). User may adjust height as normal from default.

2.406 (Note: new pmx.tex)

• Allow explicit double sharps and flats in chords.
• New option Aph to write \special{header=psslurs.pro} top of each page, so dviselec will work OK.
• Bugfix in pmx.tex for system spacing equalization by Ae, to correct behavior when top staff is smaller than others (was giving smaller space after first system than others).
• Bugfix in line-break tie option Apl, to correct behavior when there is more than one staff in an instrument.
• Internal change in storage, transparent to user: Use only first 4 bits of mult for multiplicity+8, so rest can be used for other stuff.
• Bugfix: Move stemlength stuff in nacc(27-30) to mult(27-30) to remove storage conflict with dot movement stuff.

2.407 (10/20/02) (Note: new scor2prt.for, .exe)

• Allow AN[n]"[user-defined-part-file-name]", where n is instrument number and quotes are rquired around file name. Place before first bar in pmx file for score, Syntax-checked but not used in PMX. Interpreted by scor2prt and allows you to name the part files as you please.

2.408 (2/8/03) (Note: new pmx.tex)

• Bugfix: admit pnotes{x} when x>9.995. This is only needed for notes groups longer than a breve (double whole note).
• Bugfixes in \liftPAuse and \liftPAusep.
• With postscript slurs, for up-stem single graces slurred to down-stem main note, shift slur start left by 0.8 so slur doesn't get too short.

2.409 (6/8/03)

• Bugfix: In docrd for MIDI, use original pitch in case main/chord were switched due to 2nds.
• New syntax: Use ":" (colon) before 2-digit instrument numbers in movement break command.
• Bugfix: Adjust output formats for \setname at movement break to allow instrument numbers >9.
• Bugfix in coding to raise barno due to slur over line break (pmxb)

2.410 (6/28/03)

• For non-beamed xtuplets, you can activate Col. S.'s brackets (with the number inline with the bracket) with "AT". You must have tuplet.tex installed in your TeX structure. You don't need to change anything else in the PMX input.
• To tweak the slope of the bracket for a non-beamed xtuplet, use "s(+|-)(integer)" as a sub-option to "n" in the first note of the xtuplet, e.g., "c04x3ns+2 d e".

2.411 (8/9/03)

• "Apl" in the preamble now activates special treatment of line-break slurs and ties (before, "Apl" only affected ties.). Specifically, it enables tweaking the ending position of the first segment (seg 1), the starting position of the second (seg 2), and the curvature of either or both. You must have musixps.tex available to TeX. With "Apl" every slur/tie at a line break is automagically broken into two separate ones (no additional PMX slur start or ending commands are required). Vert/horiz tweaks to the start of the seg 1 and the end of seg 2 are handled as before. Vert/horiz tweaks for the end of the seg 1 and start of seg 2 are entered as options in the otherwise normal command that starts the slur/tie. The option for the end of seg 1 starts with "s" (for sever or split), then the usual one or two signed numbers, then a second "s" and one or two more signed numbers for the start of seg 2. The usual curvature options "h","H","HH","f", if included in the starting command for a linebreak slur, will apply to seg 1, and if in the closing command, to seg 2. Of course, if the slur/tie does not come at a linebreak, the special position tweaks (those after the "s" option) will all be ignored, and the curvature tweaks on the closing note take precedence (as before).

2.412 (8/16/03)

• Minor changes in defaults for linebreak slurs and ties introduced in 2.411. Horizontal positions of start of seg 2 have been moved a bit to the right and made the same for slurs and ties. Vertical positions of end of seg 1 and start of seg 2 are now the actual height of start of seg 1, including any tweaks that were applied to start of seg 1.

2.413 (8/25/03)

• Several bug fixes in placement of accidentals in chords.

2.414 (8/30/03)

• Bug fix in placement of accidentals in chords.
• Change in default accidental placement for chords with exactly three accidentals and no 2nds between accidentals: they are placed in the order top, bottom, middle.

2.415 (10/18/03)

• Fix operation of "AT" option so normal xtup numbers are OK: use \xnumt instead of redefining \xnum.

2.416 (1/17/04)

• Include files have been enabled. Include files are separate text files containing arbitrary (but contextually appropriate) sequences of valid PMX commands. The commands will be inserted at a particular place in the virtual PMX file that the code processes. They will always be syntax-checked. There are two types, "global" and "normal". There can only be one global include file and it must be named pmx.mod. If activated, its contents will always be inserted right after the setup data. To activate it, two conditions must be met: (1) an environment variable PMXMIDDIR must be defined to contain a valid path, ending with "/" or "\"; (2) a file named pmx.mod must be present in the directory so defined. If PMXMODDIR is not set, or if it is defined but there is no file pmx.mod, then processing will proceed as usual. Normal include files can have any name and do not require any environment variable to be set. They are activated by the PMX command AR[filename] , placed in the .pmx file at the location where the included lines are to go. PMX will first check for the file as pointed to by [filename], which may contain a complete or partial pathname preceding the actual file name. If [filename] is not found, then PMX will look for %PMXMODDIR[filename], i.e., it will check the directory defined by PMXMODDIR if PMXMODDIR has been set. However, it is not necessary to define PMXMODDIR to use a normal include file. There may be any number of normal include files. The same file may be used multiple times. Include files cannot contain references to other include files via the "AR" command; if you do that your computer will explode. The following information regarding all activated include files will be printed both to the screen and to the .pml file: notice of opening or closing, echo of the contents, error messages pertaining to syntax errors in the included PMX commands, and an error message if PMX cannot find a referenced normal include file. In the latter two cases PMX will stop.

2.417 (1/26/04)

• Increase maximum number of text dynamics per input block from 12 to 41.
• Increase maximum length of a text dynamic from 24 to 128 characters.
• "Ap+c", "Ap-c" will increase or decrease the default curvature of Type-K postscript slurs. Such commands can be used at the start of any input block and the result is cumulative. More than one suboption "+c" or "-c" may be used in a single command. If the cumulative change goes above "HH" or below "f" a warning will be issued, the default will be set to "HH" or "f", and processing will continue. Local curvature options in individual slur commands will take precedence over the global default but will not change the default. The local option "n" in a slur command will cause the slur to have the normal curvature (between "f" and "h").
