The Vocoder of the VIRUS
”gab,” it could lead to interesting 
changes, although in most cases 
this will result in a rather sublimi-
nal change.
Vocoder Attack (Knob: FILTER 
ATTACK
, Default: 0 (left) The attack 
time of the envelope follower. This 
parameter controls how fast the 
carrier bands react on a change of 
the modulator signal’s frequency 
energy. Higher values result in a 
”flabby”, lazy, even delayed 
response from the vocoder.
Vocoder Release (Knob: FILTER 
DECAY
, Default: 0 (left) The release 
time of the envelope follower. This 
parameter controls how fast the 
carrier bands reflect if a certain fre-
quency disappears from the spec-
trum of the modulator signal. 
Here, higher values result in a kind 
of sustain in the carrier bands. 
High attack and release times lead 
to less speech recognition, 
although it is possible to create a 
really nice sounding synthesizer 
pads with.
Vocoder Source Balance (Knob: FIL-
TER
 BALANCE, Default: 0 (middle)) 
FILTER
 BALANCE creates a mixture 
of the vocoder signal and the mod-
ulator-respectively carrier signal. 
Turning FILTER BALANCE to the left 
adds a certain amount of the car-
