Well, I’ve done some speed tests for the ADSRs and I think I may need some adjustments.
At 0 (Zero) the decay/release is around 0.5mS, possibly a bit quick.
at 127 the decay/release is around 110 seconds, possibly a bit too long.
Good enough to develop with for now
Anyway, here’s the samples - http://soundcloud.com/vacoloco/egspeed-20130208
