Erica Synths Pico System III is affordable, compact, yet powerful sounding, full analogue modular system. It comes in two formats – eurorack and desktop.


  • 2-3-4 step sequencer
  • 2x VCOs
  • VCO controller/VCA module
  • several mixers that work both with CV and audio signals
  • Modulator (syncable LFO, random CV and noise source)
  • 2x voltage controlled ASR envelope generators
  • 2x resonant lowpass gates
  • BBD delay

Pico System III brings modular synthesis back to the basics – the system has multi functional (instead of single-function, like Pico Drums or Pico Trigger in the Pico System II) analogue modules and is intended to encourage creativity in modular patching.

The system has 31 inputs and 20 outputs (master output is duplicated) + 7 switches; if you have enough patch cables at your disposal, you can patch the system in 121000931215044250740178662400 or 1.21x1029 variations (we ignored the possibility to adjust potentiometers here). Even though only 0,0001% of all patches will sound more-less enjoyable, you and all your future generations can spend a lifetime only patching the Pico System III.

Voice-cards with preset patches set it apart from other eurorack systems – they allow user to change patches instantly and radically, which makes the system well suited for experimental live performances. The system comes with 5 great sounding “factory preset” voice-cards, and 5 DIY voice-cards that are empty and users can develop their own patches. More voice-cards will be available from Erica Synths shop.

Pico System III comes both as a desktop unit and a eurorack module. It features a set of modules for advanced sound design, experiments in modular patching and educational purposes.

Pico System III (eurorack) is named the best eurorack module of 2019 - Bo Beats

Perfect for beginners or anyone wanting a lot of functionality in a small space. I would have no hesitation in recommending the Pico System III to anyone considering embarking on a modular journey. It will make an excellent gateway into the world of analogue modular. The value for money is incredible. When you divide the cost by the effective number of modules you receive, it works out around £30 per module. If you enjoy a bit of DIY tinkering, the voice-cards may make it a unique proposition too. Overall, it’s another miniature winner from Erica Synths. - Sound On Sound

The Pico System III is a completely analog modular system with 13 Pico modules and preset memory. The good selection of modules allows a large number of patches and is ideal for learning analogue synthesis. The Pico System III is small and above all cheap, which makes it a modular synthesizer for everyone. - Bonedo

The sound out of the box is very unique, sometimes rough or even a bit harsh - with all limitations it's an inspiring little tool to experiment with - it's like a basic LEGO set, you can build everything - with some simple parts. Compared with Make Noise 0-Coast or Moog Mother-32 (I had played both) - I would say that The Pico System III is way more a real toy - in the sense of exploring sounds paired with randomness and fun. It's the right tool to get a break from the big system approach. - RED @ Muff Wiggler

The concept of the Erica Synths Pico System 3 modular synthesizer is truly accessible and suitable for both beginners and advanced users. All in all, a clear buy recommendation, because there is nowhere more modular for less money than from the Latvian Erica Synths. -
