Just a few cents of personal knowledge here;
A lot of people store MIDI instructions at the beginning of MIDI files, such
as setting channel volumes, panning, vibrato, instruments, tempo, etc.
As a general rule for someone setting information at the front of the music,
it lasts a bar or some amount of musical measure. Thus, while the MIDI
sequencer is setting instrument information, there's a second or so of
silence. This may be the delay that's being experienced, and possibly why
two MIDI handles are being requested. Some people do it with XM/MOD trackers
too.
