New ALFA AS3350 - CEM3350 Filter Chips Going Into Production

"#AS3350 - (dual voltage controlled state variable filter) started evaluation.
Datasheet will be provided later."

Synths that use the CEM3350 include the Rhodes Chroma, Crumar Spirit, Synton Syrinx, Digisound 80-16 Dual Resonant Filter, and Solton Programmer 24. Someone fitted this original Rev1 Prophet-10 with them as well.
