Yes, I see (or rather hear) what you mean. The adsr from the library
doesn't properly deal with zero sustains. Sorry, I don't have a ready-made
solution for this. Any dsp buff here who knows how to do an envelop which
enters the release phase immediately after attack (i.e., like ASR, but
without the S)? This shouldn't be too hard to do, but I can't wrap my head
around it at this time in the morning. ;-)
