Changes from PMX 2.4 to PMX 2.6

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").

2.501 (Note: new scor2prt)

• Bugfix: initialize index in PMX subroutine putorn to eliminate subscript error detected in some compilers
• Bugfix in scor2prt: Ignore special treatment of special symbols if they appear between double quotes.
• Tweak: move end of first part of line-break ties slightly to the right.

2.502 (Note: new pmx.tex)

• The height of a figured bass vertical stack can now be adjusted upward by an integral number of \internote by appending "+" and the number. Recall that it can already be moved downward 4\internote by prepending "_" (underscore). The two options can be combined to provide full control over the vertical position.
• Ties can now be represented with braces "{" before a note and "}" after. Both are equivalent to "t" after the note. (Thanks to Dirk Laurie).
• In pmx.tex all the commands of the form \font\...=\fontid sy1000 have been changed to \font\...=cmsy10 (Thanks to Olivier Vogel).

2.503

• Enable arpeggio left shift with ?-[x]
• Allow musicsize of 24 and 29.
• Bugfix: Fix bug introduced in 2.415 which caused error in printing replacement number in xtup.

2.504

• Gap between normal grace and main note: X[x] as option to the G command, where x is the gap size in notehead widths.
• Bugfix: og (segno) now works OK when nv .ne. noinst.

2.505

• A new global option AK activates special rules for vertical positioning of rests in two-voice staves. By way of background, without the new option, rests in two-voice staves have default positions based on a simple rule that is not context-sensitive: those in the lower voice (the one before "//") are 4\internote below their single-voice default positions, and those in the upper line are 2\internote above the single-voice default. The new option invokes a set of context-sensitive rules to set the default position. The baseline rule is to align the rest in a horizontal line with the next following note in the same bar. If there is no following note in the bar, then it is aligned with the next prior note. If there are simulataneous rests in both voices, the old rule is applied. When the AK option is in force, it only affects places where there are two voices in a staff. It may be toggled on and off at the beginning of any input block, using just AK. When the option is in effect, any user-defined tweaks on the height of a rest will supersede the option for that particular rest, i.e., the tweak will be applied relative to the single-voice default position.

2.506

• Fixes a bug in AK. Simultaneous, equal-duration rests will be positioned according to the default rules.

2.507

• Enhancement to global option AK for vertical positioning of rests in two-voice staves (see version 2.505): The option L ("look left") in a rest will cause the vertical position of that rest to be based on the preceding note, rather than the following one as is the default when AK has been issued
• Partial bugfix: In unbeamed xtuplets, the length of the bracket and position of the number are now adjusted to account for any inserted hardspaces.
• Bugfix: unbeamed xtups with two flags are now allowed.

2.508

• Allow grace notes in xtuplets.

2.509

• Correct small bug in arpeggio left-shifting (it got confused when there was more than one voice on a staff).

2.510

• Bugfix: Correct omission of character variable declarations in new subroutine getgrace introduced in 2.508.

2.511 (Note: new scor2prt named s2p2511.exe)

• Bugfix: Correct error in horizontal spacing introduced in 2.507.
• Experiment: Remove prohibition against tempo changes in MIDI macros.
• Bugfix in scor2prt: Make it work right when "R" command occurs at end of input block and "/" is on next line (as produced by M-Tx).

2.512

• Enable multiplicity down-up "][" within xtuplet

2.513

• Bugfix: If there is more than one rest at start of a beamed xtuplet marked as a forced beam, beam height and slope tweaks are now properly handled.
• Bugfix: If an xtuplet with multiplicity 2 or 3 starts with a rest, the rest is now printed correctly.
• Bugfix: Unbeamed xtuplets (with option 'a' on first note) with multiplicity 2 or 3 are now printed correctly.

2.514

• Bugfix: Correct horizontal spacing when after-grace is immediately followed by normal grace.
• Bugfix: Correct transpose register when it has been changed in a single after-grace.

2.515

• Bugfix: Correct error in automatic forced beams. Before the fix, if the beam did not start an integral number of beam durations from the start of the bar, incorrect results would occur.
• Bugfix: Properly center fermata over centered whole-bar rest.

2.516 (Note: new pmx.tex)

• Allow figures in voice #2.

2.517

• Allow figures in two voices, voice 1 and any other one.

2.518

• Bug fixes in 2-voice figures.

2.519

• Fix bug that prevented \sk from being output, misaligning some voices.

2.520

• New feature: special characters 2+, 4+, 5+, 6+, 9+ for figured bass. In the PMX string for any figure, follow the number by 's'. This uses the font cmrj from the new package figbas. You must install this font in your TeX setup for this to work.

2.521

• Bugfix: Font definition syntax corrected so no extra space is introduced.

2.60 (Note: Requires MusiXTeX T.115; new scor2prt.tex)

• Many mods to allow 24 voices.
