Erica Synths - Black VCO Expander essentially is advanced waveform mixer plus two octaves down suboscillator, and it allows you to explore wave design in brand new areas.

NB! This is expander module that can be connected only to Black VCO. It will not work as standalone eurorack module.

 Features:

  • Waveform mixer/inverter
  • Sine/Triangle/”Tits” waveform switch
  • Transistor-based -2 octave suboscillator
  • -1 and -2 octave suboscillator crossfade
  • Suboscillator lowpass filter
  • Diode limiter on output signal amplitude
  • Three simultaneous outputs

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.
