••
Cutoff control: Drag the handle horizontally to set the brilliance of the signal.
••
In a lowpass filter: the higher the Cutoff frequency is set, the higher the frequencies of signals
that are allowed to pass.
••
In a highpass filter: Cutoff sets the point where low frequencies are suppressed.
••
In a bandpass, band reject, or peak filter: Cutoff sets the center frequency of the band that is
allowed to pass, is suppressed, or is emphasized.
••
Resonance control: Drag the handle vertically to emphasize or suppress portions of the signal
above, below, or surrounding, the defined cutoff frequency.
••
Key (Follow) slider: Move to determine the effect that keyboard pitch (the note number) has on
filter cutoff frequency modulation.
At the top position, the filter follows keyboard pitch, resulting in a constant relationship
between cutoff frequency and pitch. This mirrors the properties of many acoustic instruments
where higher notes sound both brighter in tone and higher in pitch. At the bottom position,
the cutoff frequency does not change, regardless of which key (pitch) you strike. This makes
the lower notes sound relatively brighter than the higher ones.
••
Filter FM knob: Rotate to set the intensity of filter cutoff frequency modulation with Oscillator
1’s sine wave generator. Positions to the left set the strength of static sine wave modulations.
Positions to the right set the strength of envelope-controlled sine wave modulations.
The centered (off) position disables filter frequency modulation by Oscillator 1’s sine
wave generator.
Note: Oscillator 1’s sine wave generator always generates a sine signal—at the frequency of
Oscillator 1.
••
LFO knob: Rotate to set the strength of filter cutoff frequency modulation with the LFO.
Positions further away from the centered (off) position make modulation more or less intense.
See Retro Synth LFO and Vibrato.
••
Filter Env(elope) knob: Rotate to set the strength of filter cutoff frequency modulation with the
Filter Envelope. Positions further away from the centered (off) position make modulation more
or less intense. See Retro Synth envelopes.
