abc2midi bug: I could not demonstrate this bug on my own system.
When abc2midi is compiled on a Debian linux system using the -O2 compilation
flag (by default), it produces a faulty midi file for abc files containing
gchords. Here is a sample file.
%abc-2.2
X:1
T:Test
M:C
L:1/4
Q:1/4=135
V:S clef=treble
V:s clef=treble
K:C
%%score (s S)
%
[V:s] "C" x2 "a" x2 |
[V:S] C C A A |
The problem occurs with the bass accompaniment generated by "a". The
bass accompaniment creates a long string of A,, notes.
This problem disappears when abc2midi is compiled without the
-O2 optimizer.
Analysis: the bug was traced to the code gchord_configure in genmidi.c.
The limit of the loops
for (j=0; j<chordlen[chordnum]; j++)
contain bad data when chordnum is set to -1 (for bass accompaniment).
Fix: exit from gchord_configure function when chordnum is less than
zero.
The problem was identified to me by Jakob Englhauser. Jakob verified
that this fix works.
April 06 2022 midi2abc: removal of spaces in text strings for control
messages.
April 27 2022 abc2midi: Recanting change from February 18 2022.
The swap was incorrect.
Fix: swapped p2 and p1 in
*transpose = p2 - p1;
in parsesound() in parseabc.c
abc2midi now transposes this file correctly.
X:1
T: transposition
M: 4/4
L: 1/4
K:Cm
V:1 shift=cF
cdef|gabc'|
V:2 sound=cF
cdef|gabc'|
V:3 score=cF
cdef|gabc'|
V:4 instrument=cF
cdef|gabc'|
Note that the command instrument=cF is not part of the abc standard
and abc2svg does not recognize it.
