The 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 (via “FX” – apply FM, phase distortion, ring modulation, wavefold/wavewrap, bitcrush)

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