Or you want to have probably a master instrument that calls the ones in the group. That could take care of stopping previous instrument with turnoff2 when it calls the new one with schdulek or event opcode.

Please let know if you need more hints!

hello gabriel, 

i guess there should be a better solution but i can only think of building this yourself with "active" and "turnoff2" opcodes. like:

if active(1) >= 1 then 

turnoff2 2,0,0

...

endif

i hope that's what you meant.

good luck -

Hello, everyone

I am just curious about something. Is there a way of setting up choke groups for instruments in Csound -- meaning, out of a selected number of instruments, if this one plays stops the other? This behaviour would be similar to that of music tracker, or some samplers as well. I am thinking of implementing this in a future project, I just don't know how to start

Thank you,

Best,

Gabriel

If you are using Csound 7 you can use maxalloc with iturnoffmode.  Mode details can be found here: https://github.com/csound/csound/issues/1995

maxalloc insnum, icount, iturnoffmode

insnum: Instrument number.
icount: Maximum number of instances that can be allocated.
iturnoffmode (optional): Specifies the behavior when the icount limit is reached. This parameter can take the following values:
0: Default behavior. When the number of instances equals icount, no new instances are allocated.
1: When the number of instances equals icount, the oldest active instrument instance is automatically turned off, and a new instance is created.
2: When the number of instances equals icount, the newest active instrument instance is automatically turned off, and a new instance is created.
iturnoffmoade allows automatically turning of previous instrument instances.
