I just checked in a new help file that uses some [osc~]s for the first 
few channels.

Some files use the MIDI noteoff message for note offs and others use 
noteon with velocity zero. Possibly drum tracks use only note ons and 
never send any note offs.

I've noticed a lot of midi files have a few seconds of nothing at the 
beginning as though they were made by recording a keyboard live (or they 
set up a bunch of controls before starting). If you note the tick at 
which the sound starts you can just specify that offset to [midifile] 
and start there.
