Wow, that's grand!

Yes, I can imagine.

We've made special arrangements for that, in particular the so-called
part-combiner (an devnull engravers).  You'll want to look at `Writing
parts' in the user manual:

in particular the section about automatic part combining:

There's a small example in the Tutorial:

which may or may not be useful.

You also may want to look at the sources for van Beethoven's Coriolan,
available from Mutopia.

Ok, I'll have a look.

MIDI is lacking some features.  It's main use currently, therefore, is
debugging the input.  Because Lily's primary focus is typesetting,
MIDI is not getting the attention it should.  These things really
should be fixed, it's not very productive to try and trick MIDI
output, I guess.

I'd advice you to split the sources up into separate files, putting
the music of each part into a file.  That way you can easily print the
full score, and print all individual parts; have a look at the
Tutorial example, or the Coriolan.

Btw, do you know about point-and-click editing:

and skipping corrected music:

may be very useful ?
