That control does not yet exist, but there are requests in the bug-tracker

LilyPond tries to assign channels for us, but it would be nice if we
could override her decisions.  If an explicit midiChannel setting simply
over-writes LilyPond's choice, that might work.  Anybody who can compile 
LilyPond and knows some C++ and a bit of MIDI might enjoy testing if this
works as expected, and maybe send a patch.

For now, I think the LilyPonds assignment of staves to channels is at
least consistent, so maybe you can inspect the output to see what staves
are what channels, and then edit the midi as you need.
