Pittsburgh Oscillator


A wide range, high quality, 8hp utility VCO.  It offers a full compliment of standard waveforms including Sine, Triangle, Saw, and Pulse waves. The Oscillator offers 5 octaves of 1 volt per octave tracking, and a frequency range starting as low as 7 seconds per cycle, allowing it to double as an LFO. Additional features include oscillator reset for hard syncing, attenuated linear FM input, pulse width, and pulse width CV input.

  • Excellent logarithmic conformance
  •  Temperature compensated 1 volt per octave operation
  • Simultaneous sawtooth, pulse triangle, and sine wave outputs
  • Sawtooth wave based oscillator circuit
  • PWM Input: 0% to 100%
  • Hard sync input
  • Below audio frequency operation

Module Controls:

  • Big Knob – Coarse frequency setting
  • Fine Knob – Used to fine tune the frequency of the Oscillator. This control is calibrated to a range of 1 octave.
  • 1V Input – CV input used to track the Oscillator at 1 volt per octave. This input also can be used as a logarithmic FM input.
  • RT – CV Input used to hard reset the Oscillator on the falling edge of the incoming waveform.
  • FM Knob – Linear frequency modulation CV input attenuator.
  • FM Input – Linear frequency modulation CV input.
  • PW Input – Pulse width modulation CV input.  Affects the pulse width of the square wave
  • PW Knob – Used to manually control the pulse width of the square wave.
  • Power Connector – +12v is at the top of the connector and -12v is at the bottom of the connector.


  • Module depth: 35mm
  • Current Consumption: 30mA
  • Panel size: 8HP
