W136 Dual Voltage-Controlled Oscillator

W136 Dual Voltage-Controlled Oscillator

This 3340 Dual Voltage-Controlled Oscillator has a smaller footprint per VCO than our standard 3340 VCO module; making it suitable for cases where space is more limited, or where you want to maximise functionality per HP.


Although more compact, each VCO features a vast range of modulation capabilities, including hard sync, PWM, 1V/octave and exponential/linear FM. All of these inputs are cascaded from VCO 1 to VCO 2, allowing less patch cables to be used.


Each VCO provides simultaneous ramp, triangle and pulse waveform outputs.


The authentic CEM3340 architecture offers an instantly recognisable, rich analog sound found in many famous synthesizers from the past, such as the Prophet 5 etc.



  • Dual version of our standard 3340 VCO; comprising authentic CEM3340 (Rev. G) architecture.
  • Three simultaneous, buffered 10Vpp (±5V) waveforms per VCO, including DC-coupled ramp, triangle and pulse outputs, with controllable PW and PWM CV inputs (0V to 10V). Pulse output is derived from the CEM3340's triangle waveform using external circuitry.
  • Individual coarse and fine frequency control knobs provide an adjustable frequency range of more than ten octaves (approximately 8Hz to 16KHz) for each VCO.
  • Each VCO has a wide range of modulation inputs; including hard sync (comparator-based), PWM, 1V/octave and exponential/linear FM (switchable). All of these inputs are cascaded from VCO 1 to VCO 2, allowing less patch cables to be used.
  • Ergonomic design.
  • Hand-built and tested in the UK.
