Re: [Doepfer_a100] Frequency-to DV-Converter. Was: bright new ideas for future Doepfer A100 modules!

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
