I want to trigger an event when an incoming audio signal (which i know is a ramp between 0 and 1), crosses some threshold.
basically i want something like
[adc~] | [last sample <= x && cur sample >x] | [a drum or something is triggered]
any ideas how i can do that? I don't see how I'd do it with just the built in objects. I realize that the bang will probably only happen at control rate..
I have another app creating this ramp, and I want to be able to sync to it in pd [probably just to trigger drum samples]

This sounds like a case where [threshold~] would be exactly what you want. It is block based, but for triggering drums it might be accurate enough (play with blocksize).
