description / manual
Cyllene offers four waveform options:
pulse wave
triangle wave
variable waveform (which blends between sine and pulse via trimmer on the back)
modulation sawtooth wave.
You can select the active waveform using the SELECT knob. This can be done manually or controlled via CV input. An LED shows which waveform is currently selected.
To tune the oscillator, use the COARSE knob for broad pitch adjustments and the FINE knob for precise tuning. The V/OCT input allows Cyllene to track pitch from sequencers or keyboards accurately across at least five octaves (1V per octave standard).
For added depth, you can blend in up to three sub-octaves with any waveform:
The BASE function adds a pulse wave three octaves below the current pitch.
The SUB section introduces two additional sub-octaves: one and two octaves below the main pitch.
Use the SUB -2 / SUB -1 control to mix between them. In the center position, both are equally present; turning fully left or right isolates one sub-octave.
A NOISE control lets you mix in white noise to enhance texture and add grit to the signal.
Cyllene also features internal frequency modulation (FM). Use the MOD FREQ knob to adjust the pitch of the internal modulation oscillator, and the MOD AMT knob to control how strongly it modulates the main waveform. The MOD SYNC switch allows you to unlink the modulation oscillator from the V/OCT input for more experimental FM tones.
The pulse width of the pulse wave can be shaped manually with the PULSE WIDTH knob or modulated externally via the PWM CV input with its dedicated attenuator.
Lastly, Cyllene includes a built-in VCA, which lets you control the oscillator's volume using an external envelope or control voltage, eliminating the need for an extra VCA module and saving valuable rack space.
