Hi all. I am taking part in a project where I will be live coding audio effects. I will be processing 2 incoming mono signals from 2 musicians. I am not sure about the best way of doing that in Csound. I have set Paul Batchelor's scripts, as he uses in this example here: https://www.youtube.com/watch?v=NjSrh71B2yo Basically, he defines instruments and then uses schedule to call them. In my case, I need one instrument defined for each musician, and these instruments would need to be permanently running, and, as I constantly edit and evaluate the instruments, I would need Csound to instantly consider each new definition of instrument as soon as possible after I evaluate it. Which would be the best way of achieving that? Just a quick example to explain a bit more. Considering this instr definition { instr 1 a1 oscili 1, 1000 out a1 endin } And then this line to schedule it to play for a lot of time { schedule 1, 0, 10000000 } After the scheduling I immediately get the 1000 Hz sine. I would like to know how to evaluate the instr 1 definition again, changing "1000" to "2000", and instantly have Csound considering the "new" definition. Thanks a lot for your guidance. All the best, Antonio.
