Without patch cables modifying the signal, it can modulate the frequency of the VCO and the filter cutoff.
The neck had spring-loaded wheels for filter cutoff, modulation, and volume as well as a ribbon-controlled pitch bend.
Keyboard velocity can affect volume and/or filter cutoff.
Top mounted foot controlled sliders affecting volume (Loudness) and filter cutoff (Filter) were also provided.
Most of performance parameters can be altered on-the-fly in analog style, like filter cutoff, resonance, attack, release, there are four assignable sliders for that.
This style of bass is typically produced by using a low-frequency oscillator to manipulate certain parameters of a synthesiser such as volume, distortion or filter cutoff.
The resulting sound is a timbre that is punctuated by rhythmic variations in volume, filter cutoff, or distortion.
The filter cutoff can also track the keyboard to allow high harmonics to be heard on higher-pitched notes.
The keyboard was aftertouch-sensitive and on its neck featured spring-loaded wheels for filter cutoff, modulation, and volume as well as a ribbon-controlled pitch bend.
