Hi,

Say I have this instrument:

instr 1
    event_i "i", 2, 5, 1
endin

If then, say from "instr 3", I use turnoff2 to kill instrument N.2 
BEFORE the start time in p2, obviously turnoff2 doesn't work. This is I 
think because instrument 2 isn't actually playing when you trigger the 
turnoff.

I have found solutions to the problem by using a third instrument with 
p2=0 and a timer. So I kill this "proxy" instrument instead and that 
solves my problem.

But I wonder, is there's something you could do to "unschedule" an 
event_i with delayed p2?

Thank you.

I am afraid no.
If an event is scheduled, it will be started. But you can use some global variable as flag that signals if instr 2 is allowed to play. And have a line in instr 2 that turn itself off if the flag is set.
Would it help?

This sounds like a very complex setup. I've found that people often over complicate instrument design when starting off Cabbage. I wonder if your whole approach couldn't be simplified?

Hi Tarmo.

Unfortunately, it would not. Because I might want to execute the following order:
1) cancel p2-delayed instruments
2) start instr2 with p2=0 set, immediately.

This 2 sentences are actually a Start/Stop button. And as you can't cancel p2-delayed instruments, I get overlapping instances of p2 (because the first order doesn't "unschedule" the delayed instance).

Anyway, my trick with the "proxy" instrument works fine. I just wanted confirmation that it is not possible to do it.

Cheers.

I'm honoured to be mentioned in the same sentence as Iain! I'm going to print this email and stick it on my fridge :)
