Right.  Using many ports, (if fact, one port per track), it would be
trivial to encode voices and map them to tracks.  In fact, the current
midi2ly implementation would do just that.

It seems that this port extension is not implemented, generally.

I think this is the best solution, although I think it's a custom
solution and thus clumsy?

I'll be looking into this.  I think I'll be doing

    No Port setting (ie, single port)
    midiInstrument <-> Channel 
       (possibly with option: Staff_performer <-> Channel)
    Voice <-> Track

Also, I'll be adding a midi test suite, mainly for midi2ly but this
will test midi output too.

Jan.
