[sdiy] Re: [AH] CEM / SSM Chips used in non-synths?

[Sean Costello]

What are the new CEMs called? I know that they are not technically CEM, but
Doug Curtis designed a chip that was originally intended for the Marion
Systems (is that the name? ya know, Oberheim's company) synth, and is now
used in the David Smith Evolver and Polyevolver. Does anyone know what this
chip contains? Presumably a filter, but is there also a VCA? VCO or two?

Thanks,

Sean Costello
