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.
