Erica Synths Graphic VCO allows you to draw your own waveforms, arrange them in wavetables and wavetable banks, morph between two selected waves, and alter the resulting wave in advanced ways (FX) – apply FM, phase distortion, ring modulation, wavefold/wavewrap, bitcrush.

Waves, wavetables, FX, and other settings can be saved and recalled from memory instantly. The module has two outputs – the main output and the output with configurable suboscillator.

NB! To keep the module functionality up to date, we recommend you check the Erica Synths home pageor our social media from time to time for announcements about firmware updates for the Graphic VCO. You can update the firmware of the module via miniUSB cable. More detailed instructions for the firmware update can be found in the User Manual.

The sound is clean, modern, punchy, and detailed thanks to the unit running at 96kHz — quite different from some low bit-rate wavetable oscillators on the market. Wavetable interpolation is smooth as butter, and with the built-in effects, you can dirty things up in many different ways. The module scores highly on the sound front. The Graphic VCO is a very capable oscillator module with excellent sound quality and a lot of features that could make it the right choice, especially if live performance is your thing. - Sound On Sound

The bottom line is that the Graphic VCO is a joy to use. It’s a module that’s unashamedly digital, yet unmistakably Eurorack. I think Erica showed a great deal of careful judgment and restraint in the design of this module. It would have been easy to make it bloated and cumbersome by trying to cram as many features as possible into it, but they kept it fairly simple which keeps the module fun and immediate to use. It’s capable of a huge tonal palette ranging from beautiful to brutal that is bound to fit in with a lot of different styles and systems. - Ask Audio

The ability to draw and then effortlessly jump between different custom digital waveforms in this way feels unique on the Eurorack stage, and allows for a wide range of tones and transitions between them. - Orb Mag

One of the greatest music producers of our times - Randall Dunn recently wrote a little piece about sounds he loves. He says: “We were both pretty hungry in Michigan in the 80's looking for new sounds and music. [..] Mostly played on Synclavier and a Roland JD 800 I began a strange love affair with late era digital synths like those and the PPG wave and why sometimes I still prefer the brutality of a wavetable to a Minimoog.” 

Of course, everybody loves the sound of an analog synth. It is an unquestionable core value of a huge and influential tradition started in the second half of the 20th century. However, if you are bored even for a minute of taking part in that old collective ritual of millions, if you feel that rebel growing inside you, if you are eager to discover your own path, your own signature sound, if you really want to jump into tomorrow now…, then Graphic VCO is your essential ally. Draw your own waveforms. Sculpt your own voice. Master your own musical gesture. And you may find yourself in a new beautiful world. Indeed. 

As Leonardo once said: “If I had a Graphic VCO I would have never wasted so much time with those noiseless paintings…”
