It works very well but i cannot understand how. someone could explain me in details please?

Sorry for my bad english.

The autor of the patch confirm that the comment "release" and "attack" must be switched. Now I have another problem...why the velocity 0 controlled the release? And attack?

Thank you very much!!!
I have some specific question:

1. Why the right outlet of sel is /127? (why 127??) Probably it'is a control of the amplitude (sustain) but why this object (/ 127) is necessary? I tried to eliminate it and the output sound is terrible!! Why??

2. Why after line~ there are 0 and 10?

3. I think that the release control doesn't work, the rapidity of volume decrease is the same!
