Midistats returns track activity (note on/off) for every track.
November 1 2023
Midistats returns the control volume settings for every track,
identifies midi files whose note timings are not quantized.
November 2 2023
abc2midi bug: In the following example, not all notes are
tied correctly.
X:1
T: tied note
M: 2/4
L: 1/4
K: C
D2-|:D2 |[1CD-:|[2CD|
No fix is available.
November 8 2023
midistats: extended the size of arrays (midievents and pulsecounter) to
handle certain midi files. The function stats_interpret_pulseCounter()
can detect midi files containing triplets and nonquantized notes.
midicopy: extended to handle midi files with up to 150 tracks.
