can detect midi files containing triplets and nonquantized notes.
midicopy: extended to handle midi files with up to 150 tracks.
December 17 2023
midicopy: The midi program number is not set properly for a few the
midi files where the channel program numbers are set in a separate
track. Midicopy processes and copies the tracks sequentially, and
by the time it sees the channel program numbers in the separate
track it is already too late. It would be necessary to rewrite
midicopy so that it stores the entire midi file in memory prior to
copying it to disk.
midistats: Introducing a new option -nseqfor n where is a channel
number. See drums.txt for a description.

each value in the -ppat listing is given. The number in parentheses
splits the two 4-bit values with a period. Thus 33 = (2*16 + 1).
-nseqfor -n
Note sequence for channel n. This option produces a string for bytes
indicating the presence of a note in a time unit corresponding to
an eigth note. Thus each quarter note beat is represented by two
bytes. The pitch class is represented by the line number on the
staff, where 0 is C. Thus the notes on a scale are represented
by 7 numbers, and sharps and flats are ignored. The line number is
then converted to a bit position in the byte, so that the pitch
classes are represented by the numbers 1,2,4,8, and etc. A chord
of consisting of two note onsets would set two of the corresponding
bits. If we were to represent the full chromatic scale consisting
of 12 pitches, then we would require two-byte integers or
twice of much memory.
Though the pitch resolution is not sufficient to distinguish
major or minor chords, it should be sufficient to be identify some
repeating patterns.
