Functioning as a quintessential VCO, it boasts a 1V/OCT input, both linear and exponential frequency modulation inputs, and comprehensive control over pulse width modulation. To manage incoming control voltage effectively, dedicated attenuators accompany each of the aforementioned inputs. ​

Cyllene's oscillation spans the gamut from supersonic to sub-audible frequencies, endowing it with the versatility to serve as an LFO if desired. ​

Beyond the realm of classic VCO attributes, Cyllene incorporates an integrated frequency divider. Through the SUB output jack, it delivers up to 3 sub-octaves in relation to the original signal. Fine-tuning the volume of each sub-octave is facilitated by the potentiometer seamlessly connected to SUB 0-8. By toggling the SUB ORIG switch, the choice between the original signal and a generated square wave on the initial octave is at your fingertips. Furthermore, the SUB WAVE Switch allows you to designate the source wave for the frequency divider.
