Hi Don,

if you don't need things to make very sudden changes (i.e. less than a
few milliseconds), you could send OSC messages via PD or Max through the
Arduino and smooth them out with a slew limiter. I have a homebuilt
version of the "Dual Bissell Generator" which does this just fine on the
slowest slew setting, and it still feels pretty responsive. And with the
newer Arduino, using the Atmega 168 chip, you get 4 PWM outs from the
Arduino, which is enough for a couple voices if you use the digital outs
for gates. I guess we're moving more in to Synth DIY territory now,
since I guess this list is more for plug-and-play solutions... but at
least I can say it's possible.

For a module, it would be nice to have more than 4 channels (maybe even
16), perhaps a slew limiter built in to each channel or an overall slew
limit setting. Oh yeah, and not to have to build it myself ;-)

best!
Derek
