MIDI channels

[Martin Tarenskeen]

Hi,

I am trying to produce some tunes and exercises for my pupils for 
PianoBooster ( http://pianobooster.sourceforge.net/ ) using LilyPond.

For this purpose I need to write a pianotune that uses MIDI channel 3 for 
the Left Hand part, and MIDI channel 4 for the Right Hand part. A bit 
strange, I agree, but this is what the PianoBooster docs tell me to do.

Can Lilypond be tweaked to produce this? It needs to produce a readable 
PDF as well as such a MIDI file.
