October 29 2014
Abc2midi: more work was done with the bar repeat code in store.c
Abc2midi returns the incorrect line number when it detects a
problem with bar length on repeat.

Abc2midi bug: the b code in the gchord string does not work
correctly when there are inversions. eg.
November 9 2014

Changelog:
November 18 2011
Abcmidi new feature. The MIDI commands, chordprog and bassprog have
been extended to allow for an octave offset. In the following example
November 30 2011
Abc2midi slurring bug.
December 8 2011
Abc2midi: fermata bug. When a rest is preceded by a fermata symbol
H, abc2midi fails to recognize the rest.
December 11 2011
Abc2midi: lyrics bug with inline voices.
December 19 2011
Abc2midi clef-octave bug. In the following example, the clef=treble
declaration does not restore the octave setting to zero.
January 29 2012
Abc2midi: extended %%MIDI chordname command to handle up to 10 notes (instead
of 6).
March 08 2012
Abc2midi: grace bug with voice overlay. Abc2midi loses synchronization when voice overlays and gracenotes present.
March 22 2012
Abc2midi repeat error message:
abc2midi runs without error messages if the tunes are processed
individually.
March 26 2012
Abc2midi fermata bug:
March 29 2012
Abc2midi bug: abc2midi applies fermatas to all chords in which the
length is set outside the chord.
March 30 2012
Abc2midi bug: more bugs when fermata is applied to a chord.
April 1 2012
Abc2midi: new feature. Introduced a new option (-TT) to tune the key of
A above or below 440.0 Hz but less than a semitone. The output MIDI
file will re-tune to that frequency. The purpose of this feature
is to accommodate some instruments like the accordian which are
not tune exactly to 440.0 Hz.
April 03 2012
Abc2midi -tuning. Changed to the lower frequency limit to 414.9 to
permit A=415 Hz, a common tuning for Baroque music. The bend
variable is still limited between 0 and 16383.
April 15 2012
Abc2midi - lyrics. The function checksyllables() in genmidi.c emits
warnings even when there do not seem to be any errors in the
placement of the lyrics. I do not know how to fix this problem,
or even whether a fix exists. Furthermore, the warnings do not
appear useful as they are not very specific. Users can easily
check the placement of the syllables by viewing the score produced
by abcm2ps. The error message in checksyllables() is now suppressed
except when running abc2midi in verbose mode.
Changelog:
October 21 2011
Abc2midi bug: %%MIDI control command after a rest causes loss of
synchronization. In the following example
X:1
T: Synchronization Loss after rest (z2)
V:1
V:2
M: 4/4
K:F#dor
V:1
|: A,G, | F,G,F,G, A,B,A,G, | F,4-F,2 :|
V:2
%%MIDI program 65
|:\
%%MIDI control 7 40
de| f4 z2
%%MIDI control 7 80
GA| f4-f2\
:|
The control command is used to modulate the loudness of the alto saxophone
in voice 2. The second control command which attenuates the saxophone
to velocity 80 introduces another delay of z2 causing the following
notes G and A to be played one beat late (into the next bar).
Analysis: The second control command introduces a beat delay because
delta_time is not zero when the function write_event is called. (Delta_time
is not zero after a rest so that the following note will be delayed.)
Fix: write_event should not introduce any delay, so that delta_time was
replaced by 0 in the function call mf_write_midi_event(..). The function
write_event is also called to turn on (off) portamento, to handle
pitch_bend, pedal on and pedal off MIDI commands. (Hopefully, this
change does not introduce a bug in the other functions.)
Apply security patches from Debian.
Changes include:
(Mike Scott) The 'y' spacing character used by Barfly and
abcm2ps was being silently dropped in parseabc.c. Added
support for this (including a length specifier - is this
used by anything?) to parseabc.c and abc2abc.c; stubs in
the other modules including yaps mean they behave as before.
