The heart of a modular synth - voltage controlled oscillator.


  • Years of MFOS VCO improvements all rolled into this design.
  • Good tracking over several octaves (6 to 8).
  • Can be temperature compensated with a metal film 2K Ohm 1/4W +/-2% T.C. +3300 PPM tempco.
  • Simultaneous Rectangle, Ramp, Triangle and Sine Outputs (Ramp core design)
  • Designed for 1V/Octave control voltage
  • 4 1V/Octave control voltage inputs.
  • 1 Linear control voltage input.
  • Hard sync input.
  • Rectangle wave duty cycle adjustable between 10% and 90%
  • Rectangle wave duty cycle voltage controllable
  • Frequency range is from sub audible (approximately 0.1 hertz) to ultra-sonic 20kHz.
  • Power supply can be +/-12 or +/-15 volts.
