Kassutronics VCO 3340

Just another 3340 VCO. This chip is used in a lot of VCO these day’s. The CEM3340 chip was achip used in a lot of older synths like the Roland SH-101, the Sequential Prophet 5 (Rev.3) and more. Electricdruid.net has some schematics and more background information on that online https://electricdruid.net/cem3340-vco-voltage-controlled-oscillator-designs/

The CEM3340 VCO chip has been re-released. It has also been cloned by CoolAudio as the V3340 and by Alfa as the AS3340. You can put any of these in the VCO 3340. I think I’ve put Alfa version in mine. But have to double check that.

It’s a nice and small VCO by Kassutronics and sounds pretty good.
