Subject: Tech Question Regarding CS-80 Ring Modulator

From: "elie" <elieman@...>

Hi, I'm implementing a CS-80 Ring Modulator design on another Yamaha Synth. No problem getting the Modulator & buffer amps, VCO chip but the VCA (IG00151)and Envelope Generator (IG00159) are not practical to purchase.

My question is if the VCA and Envelope Generator are Linear or Exponential in function?...not sure if the service manual might answer that so just in case anyone knows?

Thanks!
