Multi-track MIDI files are played back using separate callback chains for each track, and this introduces the possibility of one track becoming out of sync with the others. This was noticeable in WADs that use multi-track MIDIs, such as Alien Vendetta. Increase the timing resolution to microsecond precision to fix this.
