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
ATTAC K, 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-
