The parameters of the VIRUS vocoder
This picture shows the filter section in
vocoder mode.
Modulator Frequency Offset
(Knob: CUTOFF 2, Default: 0 (middle))
A linear shift of the modulator
bank’s central frequencies
against the carrier bank, results in
pitch-shifting and ”mickey mouse”
effects. CUTOFF2 creates an offset
of the modulator to the carrier
bank.
Q-Factor (Knob: RESONANCE,
Default: 0 (left) The resonance
parameter controls the quality of
the filter bands (like an equalizer’s
q-factor). Depending on the filter
select setting, the banks are
adjusted together or independently.
FILT1 is assigned to the carrier,
FILT2 controls the modulator. A
low quality factor of the carrier
bank leads to a fairly neutral reproduction
of the carrier signal. A
higher quality creates a higher resonance
in the filter bands, which
therefore make the overall sounds
more artificial. The effect is less
effective on the modulator bank.
Here, the filter quality controls the
”gab” in between the individual filters.
Depending on the modulator
signal, if you soften or tighten the
