New issue 2278 by address@hidden: Command to tell each staff to change  
MIDI channel and port
http://code.google.com/p/lilypond/issues/detail?id=2278

dear composers and programmers,

i need more functions for midi with lilypond. i know - lilypond is NOT a  
sequencer, but i try to tell you, what i want (and i read this wish in a  
forum,
too)

i work often with the linuxsampler, frescobaldi, lilypond and jack. for my  
first piano concert i need more samples than 15. i try to explain with an
example:

on midi-channel 12 there is the violin. in the linuxsampler is loaded the  
sound for violin-sustain. this is ok for the first 4 measures. but then, i  
need
staccato-violins. and later some other articulations of the violins. i can  
load all these sounds into the linuxsampler, but i am running out of
midi-channels.

now my suggestion:

create one command, that can not only change the instrument name. create a  
command, that tells every staff (or even every voice) to change the midi
channel AND the port. perhaps it can work as follows:

linuxsampler (1) on port 128:0 with all sustain-sounds
linuxsampler (2) on port 129:0 with all staccato-sounds
linuxsampler (3) on port 130:0 with all solo-sounds

perhaps the command can look like this:

c4 d e f\midiChannelPort #12 #128
g a h c\midiChannelPort #12 #129

so you can change each channel with additional the port. so, the number of  
midi-channels are no problem any more!

AND: with this feature lilypond goes into the future. so, lilypond will  
have a GREAT functionality like rosegarden.
