Hi list,

What's the easiest way to have a certain branch only executed during
the last k-cycle of an instrument? The only thing I could think of is
keeping a k-rate counter in my instrument and comparing it against
p3*kr, but that seems a bit clunky. Basically, what I'd need is
something similar to the timout opcode but without the idur parameter,
so that the statement is executed exactly once. Is that even possible?

Thanks,

Alex

P.S. I'm aware that there are certain circumstances (in realtime
contexts) where it's impossible to tell when a note finishes, but in
my case all note durations are known in advance, if that helps.

Hey Tito

I thought of that and for now I think I'll have to use it, but aren't
there potential problems due to rounding issues?

Thanks,
Alex

Or you can try using  a combination of the release and xtratim opcodes.
