I'm trying to route Lilypond midi out messages to Csound. Or any midi file
for that mater.

Both trying to use midi file in (-F) or midi driver(-M), I'm unable to route
the midi channels to different instruments. For example this is what I get
in terminal when loading up midi file:

midi channel 1 now using instr 1
midi channel 2 now using instr 1
midi channel 3 now using instr 1
midi channel 4 now using instr 1
midi channel 5 now using instr 1
midi channel 6 now using instr 1
midi channel 7 now using instr 1
midi channel 8 now using instr 1
midi channel 9 now using instr 1
midi channel 10 now using instr 1
midi channel 11 now using instr 1
midi channel 12 now using instr 1
midi channel 13 now using instr 1
midi channel 14 now using instr 1
midi channel 15 now using instr 1
midi channel 16 now using instr 1

Despite having 4 instruments with massign 1,1 massign 2,2.... etc....

So how do I force midi channel 1 to become instrument 1 and channel 2 to
become instrument 2?

I think channel 1 triggering instrument 1, channel 2 triggering instrument
2 etc is default behavior.

Somewhere in your "forcing" you must be doing something that derails
that...(?)

"If *ichan* is set to 0, the value of *insnum* is used for all channels.
This way you can route all MIDI channels to a single Csound instrument"
sayeth the manual. It looks like one of your lines must do that into
channel 1?

No other instruments? Then "massign 2,0" etc to disable channel 2 [or
whatever csound instrument, if any, you'd want 2, etc, to go to]

In the manual example, they put in "massign 0,0" first to disable the
default assignments, then add the ones they want in the following
statements.'
