The Erica Synths Bassline is a monophonic synth-voice module in Eurorack format with a very charismatic sound. The voice is completely analogue, and takes its foundation from an oscillator with 3x waveforms and a transistor-based sub-oscillator. 2x additional BBD lines (bucket chain circuits) in the oscillator range enrich the basic sound with emulated VCO tuning and sounds that are more expected from a poly-synth. For processing the spectrum there is a low-pass/bandpass switchable filter available, which is sound oriented to the Polivoks and is included in Erica Synths' Acidbox. The Bassline synth-voice is rounded off by 2x decay envelopes for VCF and VCA, the tracking is tuning stable over 8x octaves and there are dedicated CV inputs for further modulations.
