VCO 3
The VCO3 pulse ➊ width is manually variable, just like in VCO2. VCO 3 generates sawtooth, sine, and pulse ❷ outputs.
The default signals to the next three FM Control inputs are from:
a) the Noise Generator
❸
b) the ADSR Envelope Generator
c) VCO2 sine
❹, which is the output of VCO2’s sine wave generator
VCF Filter Cutoff and Resonance
Filter cutoff is controlled manually by a coarse tuning slider (labeled initial filter frequency) and a fine-tune
slider.
The Q, or resonance, of the filter circuit is controlled by a single manual slider. As the Q is increased by
moving this slider from left to right, any sound below the filter cutoff is gradually lowered until only a
sharp peak sound remains at the cutoff frequency.
At this Q setting, just below the point at which oscillation begins, the filter will ring distinctly in response
to any sharply defined pulse presented to its signal input. This resonating state may be used for various
percussion effects. As the Q is raised still higher, beyond about the halfway point in the slider travel, the
filter will start to oscillate. Operating in this state, it generates a pure sine wave, even in the absence of
any signal input.
