Jim The Optigan was Rick May's. I tweaked two minimoogs for him (sold, he regrets that now) one had an elegant LA mod that put an adsr to pitch osc 3. Done with wires and one switch, no other parts. Sweet. He went to the same school with mothersbaugh and that crowd. Great bass player.

Man, small world. I'll bet the Optigan with full library was one of mine. I sold one with tons of disks. The "doubletron" black MkV and Bob's 400SM were definitely mine. That 400SM was REALLY nice.

Nanaimo's doubletron went to sarah maclaughlin and I heard Bob Rock took another to his Hawaii studio. Or maybe that's backward, its old info and I can get it wrong.

Neat. There may be another residing here soon. And possibly a third, if I can source out the missing parts (without getting a second mortgage). I've owned lots of Trons, a Chamberlin, some Optigans. Some replay keyboards are nice, some are not. Some are nightmares, and some are downright dangerous. Believe it or not, what I'd really like for the studio, is a Roland D50. Maybe I need to release my inner Enya. A Linn would be handy too.

Hey thanks Dave. And yes, I do live on Vancouver Island. I operate a small recording studio that specializes in vintage keyboards. http://www.facebook.com/ApeIslandSound Are you in the area? Jim At 11:27 AM 12/17/2012, you wrote: Since all the other keys work, I would suspect the pro blem is the key it's self. Does the ProDGX use a resistor or diode keyboard? Either way, check for a bad resistor/diode on the suspect key, also look for cracked solder joints, or possibly a short to the gate or after-touch buss. On a side note, do you live on Vancouver Island?
