CEM3340 VCO Available Now

CEM3340 VCO Now Available

Our CEM3340 VCO is a straight-forward, easy-to-build implementation of the CEM3340 voltage-controlled oscillator IC by Curtis Electromusic.  The circuit was featured in 2019/Issue 3 of Nuts & Volts magazine.  To make building and using the circuit convenient, we are offering boards and full kits in both bare oscillator board format or Eurorack format. Features Square, triangle, and sawtooth waves Coarse and fine-tuning controls Adjustable 1V/O CV input Mod, PW and hard-sync inputs Reverse-polarity protected Eurorack-style power input I/O connections on...
