Product Information
Full details
The Erica Synths Pico VCO 2 is a compact, all-analogue voltage-controlled oscillator module for Eurorack systems, ideal for sound designers and electronic musicians looking to add versatile and stable analogue waveforms to their setups. Its key benefit lies in its excellent 8-octave tracking and integrated PWM control in a tiny 3HP footprint. A minor caveat is its limited output waveform selection, focusing on pulse and triangle waves.

Extended Product Information
FAQs
What are the primary waveform outputs?
The Pico VCO 2 offers Pulse and Triangle waveform outputs.
Does this module have a sawtooth or sine wave output?
No, the Pico VCO 2 does not directly output sawtooth or sine waves. It focuses on Pulse and Triangle outputs.
How does the PWM CV input work?
The PWM CV input allows you to modulate the pulse width of the Pulse waveform using an external control voltage, such as an LFO, envelope, or sequencer.
What is the 1V/oct input used for?
The 1V/oct input is used to control the pitch of the oscillator. For every 1-volt increase in the incoming control voltage, the oscillator's pitch will rise by one octave.
What is the power consumption of the Pico VCO 2?
It consumes +21mA on the +12V rail and -19mA on the -12V rail.
Can I use this module in a non-Eurorack system?
No, the Pico VCO 2 is specifically designed for the Eurorack modular synthesizer format and requires a Eurorack case and power supply.
What is the width of this module?
The module has a width of 3HP (Horizontal Pitch Spacing), making it a very compact module.
Troubleshooting
Module does not power on
Verify the ribbon cable connection to the power supply and module. Ensure the red stripe aligns with the -12V pin on both ends. Check that your Eurorack power supply is functioning correctly.
Pitch is unstable or inaccurate
Confirm that the 1V/oct input is receiving a stable pitch CV signal. Check your CV source for accuracy. Ensure the module is not overheating, which can affect analogue components.
No sound output
Check that output cables are securely patched to a destination (mixer, audio interface, or another module). Ensure the volume on your output destination is turned up. Try patching to a different output module.
PWM effect is not working
If using CV control, ensure the PWM CV input is receiving a valid control voltage. If using the manual knob, check that it is turned away from its minimum or maximum if it's acting as an offset. Verify that the output waveform selected (Pulse) is active.
Pros and Cons
Pros
- Highly stable 8-octave pitch tracking
- Compact 3HP design saves valuable rack space
- Integrated PWM control (manual and CV) adds sonic flexibility
- Robust input protection enhances durability
- Pure analogue sound generation
Cons
- Limited waveform selection (only Pulse and Triangle)
- No Sawtooth or Sine wave outputs directly
- Requires a Eurorack power supply and case
Setup, Compatibility & Care
Setup:
The Pico VCO 2 is a Eurorack module and requires a compatible Eurorack case with a power supply. Connect the module to your case's power bus using the provided ribbon cable, ensuring the red stripe on the cable aligns with the -12V pin on both the module and the power header.
Compatibility:
- Eurorack Systems: Fully compatible with any standard Eurorack modular synthesizer system.
- CV/Gate: Works with standard CV/Gate signals for pitch control. The 1V/oct input is designed for typical modular pitch voltages.
- Power Consumption: Requires +21mA on the +12V rail and -19mA on the -12V rail. Ensure your power supply can accommodate this.
Care:
- Cleaning: Dust the module regularly with a dry, soft brush or compressed air. For smudges, use a slightly damp, lint-free cloth. Avoid harsh chemicals or solvents.
- Connections: Ensure all patch cables are securely connected to avoid intermittent signals.
- Environment: Keep the module in a well-ventilated area to prevent overheating. Avoid exposing it to excessive moisture or extreme temperatures.
