Erica Synths Pico VCO is a great, deep sounding VCO with 32 selected waves – classical, fattened with sub-oscillator, FM synth and others.


  • 2 banks, 16 waves each
  • VCO/LFO mode
  • Voltage controlled wavesurfing
  • Wave morphing in LFO setting

Typically you would need several rather expensive modules to generate similar sounds, besides there's an extra feature – flip a switch, and you have a versatile LFO.

With Pico Series we challenged ourselves – can we make ANY superior functionality synth module 3HP wide and affordable? Yes, we can.

Technical specification:

VCO frequency range30Hz – 5kHz
LFO frequency range0,1Hz – 20Hz
1V/Oct input signal amplitude0V – +10V
Output amplitude10V ptp
Power consumption+26 mA, -4 mA
Module width3HP
Module depth35 mm

FAQ question_answer

  • The 1V/Oct input of my Pico VCO doesn’t respond to external CV signals anymore. What should I do?
    There is a chance that you have switched your module to the calibration mode (both knobs all way clockwise and both switches up) and accidentally calibrated it. We suggest to recalibrate your Pico VCO. You can find the calibration instruction in the User Manual.
  • My Pico VCO’s 1V/Oct input is not tracking incoming CV signals correctly, it tracks only the highest notes from the sequencer/keyboard. What should I do?
    If the VCO tracks notes only above C4 or higher, please, make sure that the TUNE knob is all way counter clockwise, because this knob defines the lowest frequency you can get from the VCO.
  • My Pico VCO’s 1V/Oct input is not tracking incoming CV signals correctly, it tracks only the highest notes from the sequencer/keyboard, but sounds which come from the VCO are pretty low. What should I do?
    Please, make sure if your device’s output signal is unipolar (from 0V to +10V) because the Pico VCO’s 1V/Oct input is intended to track only positive CV signals. In case your device has a bipolar output signal (from -5V to +5V), we recommend you to use the Pico MScale: the upper part of this module adds +5V offset, so the signal from sequencer, which gives values from -5V to +5V for 1V/Oct, transforms into a signal which is compatible to the Pico VCO.
