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.


  • 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 one edge of board; can be connected to wires or separate control board
