DOC-MK2
A discrete analog VCO/LFO with stable tuning and wide spectral range, offering sawtooth, pulse, and triangle waveforms with pulse-width modulation, hard sync/reset, linear FM with attenuator, and exponential FM.1164
Capabilities 6
- Exponential FMexponential-fm
- Dedicated exponential FM input for frequency modulation.1164
- FM Oscillatorfm-oscillator
- 1164
- Hard Synchard-sync
- A RESET/SYNC input enables hard sync of the oscillator to an external source.1164
- LFOlfo
- A VCO/LFO mode switch allows the module to operate at low frequencies as an LFO.1164
- Oscillatoroscillator
- Discrete analog VCO with stable tuning and wide spectral range, producing sawtooth, pulse, and triangle waveforms.1164
- Pulse Width Modulationpwm
- Pulse width is manually adjustable and can be modulated via a dedicated PWM CV input accepting +/-5V.1164
