Erica Synths Black Wavetable VCO
Fat wavetable VCO with morphing, bitcrush, and sub outputs
12 HP Eurorack module
The Erica Synths Black Wavetable VCO is a compact, high-quality wavetable oscillator featuring 16 banks of 16 waves each, covering classical synths, FM synths, Erica modular sounds, vowels, and more. It offers wave morphing between adjacent waveforms, voltage-controlled wave and bank surfing, a built-in VCA, manual and CV-controlled bitcrushing, and dedicated suboscillator outputs at -1 and -2 octaves. The module has a fat, characterful sound capable of smooth evolving timbres as well as gnarly, gritty digital textures.
