For beat detection check out the beat~ object made by Tristan Jehan.

For ADSR~ you must send the value of 0 to trigger the release portion of the

For ADSR~ you must send the value of 0 to trigger the release portion of the
envelope.

I think it is both, for your project the completely worn out version 

might be fine. The Idea is to average the distance in time of events and 

take this as measure. Works fine for steady beats. You'll find lots of 

The barely touched version is to find a way to track beats also for 

accelerando and ritardando. The average method would be always way too 

late. Humans are pretty good at that though...
