I'm trying to make a custom setup for midi program change.

What I'd like to do is:

midi channel 1 plays on instr 3
midi channel 2 plays on instr 4

if I receive a program change message (regardless of what channel it is received on): 
midi channel 1 plays on instr 13
midi channel 2 plays on instr 14

I'm using pgmassign 0, -1 to disable standard program change behaviour,
and I have an "always on" instr 1 receiving the program change messages correctly.
I figured, the easiest way was to use massign inside a conditional branch in instr 1,
but it does not work (probably only works when it's in the global section).

any ideas on how to do this very welcome

Have you tried with midiin (in an ever-running instr num) and schedk 
with a set of if...goto?....(just a thougth)

That's what I do, midiin, followed by event to control the instruments. 
Then I also don't need to code instruments differently for midi, but you 
do have to do some extra work on the midi parsing end.

Iain

I was wondering, maybe I have to do it like that, yes.
I do have two questions though...

How do you handle release segment envelopes in this setup ?

And, do the extra processing (midi input and instr scheduling) induce extra latency (of one k-rate period) ?

I recall there was some code examples for this, but can't seem to find them now.

Dear all,

Sending best wishes for Peace, Joy, love and laughter to you and your 
family! And a special good whish to all the Developers of Csound.

Best regards,

I was not aware that massign actually do work inside an instr.

For my purposes, I made this csd for reassigning midichannels to instr numbers.
I know that in this simple example, a standard program change via midi wuold have been easier. But the attached setup gives flexibility for more complex mappings when needed (making a program change map that is different for each midi channel for example).

I've attached it in case anyone find it useful.
