midi channel

[Rob]

Hello!

I'm new to lilypond and trying
to arrange mulit-voice (e.g. bigband arragement).

this works find, only for the midi playback
the channel assignment of the staffs
does not always do what I expect it to do.

Is there any way to assign
explicit midi channels to voices (or staffs)?

E.g. like this:

\new Staff \with { \midichannel = 1}

Thanks for your help!

Rob
