Hi,

I guess subinstr does not take string parameters (but would be very nice, if it could - also i miss it by the schedule family opcodes). I have used scoreline in such cases.
Why your i statement line, i cannot guess, this syntax should work.
On your case would be a possible workaround to put the channel names into global string array and pass the index to subinstr.
Best!

Hi Bernt,

In the reverb instr you do:
Sleft sprintf "%s_L", p4
Sright sprintf "%s_R", p4

I guess this generates some kind of type error with sprintf, since the
variable type is ambiguous (not declared, so to speak).
This will work better:
Schan strget p4
Sleft sprintf "%s_L", Schan
Sright sprintf "%s_R", Schan

As for subinstr, yes, it probably does not take string arguments. This
would be nice to have, and natural to expect it to work just like a
score line (file an issue?).
