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. Together the Erica Black series are a range of modules that make an entire synthesizer.
NB! This expander module can be connected only to Black VCO and Black VCO2. It will not work as a standalone eurorack module.
Black VCO and Black VCO Expander is a phenomenal Polivoks sounding Oscillator with a harsh, solid, and smooth sound. The Black VCO is your workhorse. I recommend buying the combo as your sound source with an edge and brutality. The module is an outstanding implementation of the transcendent Russian synth Polivoks VCO. The blend of both modules from Erica is a real asset in my Eurorack. - StrongMocha
