MemPot, potentiometer with a memory
Remember this MemPot video?
"MemPot is a small controller circuit where potentiometer (or any variable resisor) is read and recorded with PIC (16F819) microcontroller. PIC stores a sequence of values from the user turning the knob and plays the same sequence back via serially controlled digital potentiometer (DS1267) chip. The playback speed and recording buffer can be controlled. This is a handy tool for performing gestures with electronic instruments with variable resistors as controllers."
Title link takes you to more info including links to:
* picture of the schematic (version 1.0, not tested!)
* schematic and board file in Eagle format (version 1.0, not tested!)
* PIC code (V1.0)

Update via Limor in the comments:
"this pix actually just a backup of my gallery at [link] the monstrosity you see before you is controlvoltages you can here the accompanying demo track this was used on here: [link] click here for more deets and lots more lovely pictures :)"

Another 303 Clone Shoot Out
Tom Wiltshire's Electric Druid Synth DIY Site
"I've finally got around to something that has been a dream for a long while - building my own synthesizer. My initial plan is to build a monophonic synthesizer. I intend to eventually give it memories to store sounds, but have designed it so that it works without memories if I never get that far.
I thought the easiest way to build such a synth would be using the old CEM or SSM synth chips, but unfortunately they are unobtainable for any reasonable price. However, since the late 70's/early 80's heyday of such chips, modern microprocessor technology has come so far that you can now buy a cheap microcontroller that can do a reasonable simulation of at least some of these chips. I thought this might be a worthwhile approach. So far, I've managed to write firmware for two devices, a voltage-controlled LFO and a voltage-controlled ADSR envelope generator, modelled on the CEM 3312 and SSM2056. These are presented below."
