Hi,

I'd like to get clarification on this.

1. One sequencer track is capable of addressing 16 MIDI channels.  My 
understanding is that if you've sequenced a piano and a bass line on 
the same track, then the track will be addressing 2 MIDI channels. Is 
this correct?

2. What happens if you have 2 tracks addressing the same MIDI 
channels at the same time. Is that allowed? 

3. So basically each track is a multi-timbral sequence? ... that 
might explain the need for 128 polyphony.
