ACCESS VIRUS OS4 209
The parameters of the VIRUS vocoder
rier signal to the vocoder signal. A
turn to the right adds the modula-
tor signal.
Turning the FILTER BALANCE hard
left or right can be used to monitor
the vocoder’s input signals only.
Vocoder Spectral Balance (Knob:
FILTER SUSTAIN TIME, Default: 64
(middle)) Spectral balance
between the higher and lower fre-
quencies of the vocoder signal.
This parameter works similar to a
simple equalizer, which is e.g.
capable to increase the quality of
speech. The Spectral Balance
highly influences the overall char-
acter of the vocoder.
Several vocoder related parame-
ters can be modulated by LFO-1
and LFO-2
 LFO 1 RESO 1+2 modulates the
bandpass filter quality of the mod-
ulator and carrier bank.
 LFO 2 FILT 1 modulates the
bandpass filter frequency of the
carrier bank.
 LFO 2 FILT 2 modulates the
bandpass filter frequency of the
modulator bank.
