Hello Takashi,
no, i won't say that this way. It may be right with /dev/sequencer (mode
1)
of the OSS driver. I used the /dev/sequencer2 (aka /dev/music) interface
for years with GF1 timers of the GUS Classic (3.7). Never had better
timings
for playing MIDI. I have a MIDI file (Downtown from Petula Clark, a song
of
the sixties)
Bye, Emil.
