Erica Black VCO is analogue VCO with four simultaneous waveform outputs and one octave down suboscillator.
The core of the VCO is borrowed from famous Russian synth Polivoks VCO and in exponential converter we use the original matched transistor IC that was used in Polivoks. Unlike harsh logic divider based suboscillators, Black VCO transistor-based suboscillator generates distinct, rounded squarewave. Together with Black VCO Expander – waveform mixer you get massive analogue sound source with plenty of patch points for modular use.
Features:
Simultaneous sine, triangle, saw and pulse wave outputs
-1 octave suboscillator
Manually adjustable and CV controlled pulse width
Great tracking across 8 octaves
Exponential FM input with attenuator
Synchronization input
Octave switch – 5 octaves
Skiff-friendly design
Erica Black series are high-end modules with unique functionality. Only the highest quality components are used and all inputs and outputs are protected against undesired overvoltage. When designing the Black Series, we did not economise on the module width, we put design and usability first. Big knobs are assigned to functions that make difference in sound. The Erica Black series are a range of modules that together make an entire synthesizer.
