I am looking for a patch that could identify a certain (programmable) rhythmic cell inside a stream of attacks. The input needn't be audio because I can use bonk~ to convert the attacks to Bangs.

Any clue?

Although I have no idea what state machines are, I have built something that, after reading a bit on the net, I think works along the general direction.
As I am far from being a programmer, any comments would be welcome.
Thanks for your help!
