Generating the thick and modulated sounds that you expect from an analog synthesizer, the three oscillators can be used in a variety of ways from one-part unison to three-part chords, giving you an incredible diversity of bass sounds.
By creating a sequence that uses each oscillator individually, you can create a complex pattern in which three different phrases are woven together. Using the oscillators in a 2+1 combination lets you place one set of oscillators at a low pitch and the other at a higher pitch, producing a bass line and melody simultaneously. When using the three oscillators together, you can slightly detune their pitch to generate thick unison sounds; alternatively, setting their pitch to 0, +3, and +7 will produce a chord.
The analog filter has been fine-tuned specifically for the volca bass. Turning the Cutoff knob to open the filter will make the sound brighter and more expansive; closing the filter produces a rounder and milder sound. Using the Peak knob to raise the resonance will initially produce a clean peak, and further increases will create great-sounding distortion. The resonance distortion that's so important for acid music has been tuned especially to accommodate bass sounds.
In addition to the three VCOs, the volca bass provides a carefully selected parameter structure consisting of a single VCF, VCA, LFO, and EG, ensuring that the sound that you want can be created intuitively. This is also the standard structure of a synthesizer, making the volca bass an ideal introductory instrument for learning the fundamentals of synthesizers - the enjoyment of creating your own sounds.
