Erica Synths Bassline is fully analogue synth voice module for ultimate basslines and leads. It features AS3340 VCO with three waveforms, a filter inspired by Erica Synths Acidbox and unique features - transistor based suboscillator and two BBD lines that emulate VCO detune creating a sound of massive polysynth from one oscillator. Accent provides more expression to the bassline, by adding volume and opening the VCF slightly.
