Precision Oscillator

The Serge Precision Oscillator (PCO) is Random*Source's Eurorack version, the only one Serge authorised, of Serge's legendary VCO: raw vintage sound with astonishing precision, four waveforms and both linear and exponential frequency modulation.

Key features

• SAW, TRI, SINE and PULSE outputs
• Two calibrated 1V/OCT inputs, and VC F with its knob for a processed control voltage
• LIN FM with its depth knob, for dynamic linear FM from another PCO or an NTO
• SYNC to lock it to another oscillator's fundamental, harmonics or subharmonics
• COARSE and FINE; LOW takes the range from 16 Hz - 16 kHz to 0.1 - 200 Hz, as an LFO
• Exponential response, tracking and temperature stability as the NTO's, with a variable oven temperature
