The VCO2 builds on the classic sound of this analogue oscillator by bringing in a sawtooth waveshaper and internal modulation over the shaping and pulse width modulation.


Black VCO2

Erica Synths are always looking for the little something extra to squeeze in some additional functionality. With the VCO2 they’ve got all the usual stuff covered with 7 octaves of tracking, 4 waveform outputs and a transistor-based rounded squarewave sub-oscillator, sync, linear and exponential FM and pulse width modulation inputs. Black VCOs are highly accurate and super stable so if nothing else you’ve got a hard-working oscillator you can rely on. That may be enough for the version 1 but with version 2 it needs something else.

With VCO2 Erica introduces some saw shaping. “SAWSHAPE” is wave shaping control for the sawtooth output transforming it into a double and triple saw waveform. As with pulse width modulation, there’s a dedicated knob for manual modulation and a CV input for bringing in external control. But we’re not done yet. They’ve snuck a pair of LFOs inside and tied them to the SAWSHAPE and PWM controls. You can switch the LFOs between either, none or both and then control the speed with the modulation knob.

The VCO2 is also compatible with the existing VCO expander which offers waveform mixing, a second octave down sub and colouration.

This is a useful oscillator that could save you a load of space in terms of utility and LFO modules. Having internal modulation to give the oscillator juice and movement is really helpful for smaller systems. It’s available now for €230 and the expander is €110.
