Reso (Resonance)
Range: 0 99
Controls: [CS7], [-1] [+1], Dial
Determines the degree of filter resonance when the “LPF” filter type is
selected (“--” appears in place of the resonance parameter when any other filter
type is selected).
This parameter has a similar effect to the “resonance” settings on traditional
analog synthesizer filters — i.e. it determines the height of a peak in the filter
response at the cutoff frequency.
VOICE EDIT MODE / 3:Filter
Higher resonance values produce a higher resonant peak and reduce the
overall bandwidth of the filter, passing a narrow band of frequencies at the
filter’s cutoff.
CTRL (Filter control)
Range: EG, LFO
Controls: [CS8], [-1] [+1], Dial
Determines whether the cutoff frequency of the selected filter will be con-
trolled by the LFO or by the filter envelope generator (EG).
Varying the filter cutoff frequency can create “sweep” or “wah-wah” type
effects. If the cutoff is controlled via the LFO a cyclic variation based on the
“shape” of the selected LFO waveform is produced. If EG control is selected,
the filter envelope generator (see “FILTER EG LEVEL & RATE” below) can
be set up to produce a wide range of time-based variations.
Please note that if “LFO” is selected, the filter cutoff envelope generator
parameters have no effect on the sound.
