Hi Bert -
Yes please do the back-port! The only changes you need are the one-line interpolation in the mix... method to banish noise and the refs to this.damp to make the high notes ring better.
The changes for shareable envelopes are vast - I wouldn't bother.
Keyboard sustain will be my next move (easy) but I'm not sure it would be that hard to read a real keyboard. Let's find out how to read USB input - nice for all sorts of fun hardware experiments (have you got your strawberry pie yet? ;-)

I guess we should port back your improvements :) I tried commenting out the Squeak primitive code, and found that with current CPU speeds, it is not needed anymore. On my machine the synthesis, even if interpreted, uses only about 1 % of CPU time per voice.

>>> For anyone interested, I finally got a chance to finish most of what I wanted to do. FM synthesis now works - there's a brass-like and clarinet-like patch to try. Also I added a line of interpolation to banish the noise in PluckedSounds - they're really nice now. I also refactored everything so that Envelopes are free of streaming state and thus can be shared among notes.
