- Fixed: When playing a MIDI file with EMIDI track designations to turn a

track off, any ticks that had only events on the disabled track would cause
  the delay for that track to be thrown away, and the following notes on
  enabled tracks would play too soon. This could be heard quite clearly in
  xplasma.mid, where track 4 (FMGlass Drone 1) would interfere with the timing
  of tracks 13 and 14 (EP1 Melody and EP1 Echo).

-(Note to self: xplasma.mid sounds really bad. Find out why.)
 - Fixed: When note_on() is called and another copy of the same note is
   already playing on the channel, it should stop it with finish_note(), not
   kill_note(). This can be clearly heard in the final cymbal crashes of
