Just a bit more on untangling the Melody track. It seems the SEQ button only allows me to assign patches on the Melody and Soloist track. Again, I don't really understand the rationale here, but there must be a broader application that requires this.

I've been using an F blues MIDI file that was in the BiB files, which has three channels -- bass, drums, piano. All of this is in the Melody track, and there are Play check boxes next to each, but checking and unchecking don't seem to do anything (I'm trying to kill the piano track)

Ideally I would like to move each track to the corresponding Instrument Part buttons, but don't see any way to do this
