and DECAY parameter. These signals are no

audio signals, as they contain the envelope of

the signal being analysed.

THE CARRIER BANK

The signal is treated in a similar way to the sig-

nal which passes the modulator bank. In this

case, the carrier signal is split by the bandpass

ﬁlters. Each bandpass of the carrier bank corre-

sponds to one of the modulator bank. Usually,

both bandpasses use the same frequency slice.

Similar to a synthesizer’s envelope, the signal

level being measured by the envelope followers

of the modulator, is used to control the level of

the carrier’s ﬁlter. Last, but not least, the individ-

ually controlled signals of the carrier bank are

reuniﬁed to create the vocoder’s output sound.

 THE PARAMETERS OF THE

VIRUS VOCODER

 The Vocoder related parameters are located

in the EFFECT Menu [“Vocoder” on page 94]

VOCODER MODE

here you can enable the vocoder and choose

the signal source for the carrier bank at the

same time:

- OSC This mode uses the whole oscillator

section of the Virus, including the noise gen-

erator as the carrier signal. The oscillators

can be played polyphonic which enables the

ampliﬁer envelope to work as usual. But the

oscillator signal does not pass the ﬁlter sec-

tion,

- OSC-HOLD This setting is identical to

”OSC” although the hold-mode (which also is

available at COMMON/KeyMode) is activat-

ed.

- NOISE White noise is used as the carrier.

The oscillator section is disabled.

- IN (L / In L+R / In R) The analog inputs are

the carrier signal. If a stereo source, like L+R,

is chosen, the left and right signal is mixed to

create a mono signal.

OSC VOL

OSC VOL adjusts the output level of the vocod-

er. This is independent of the signal source

(which can be assigned using the vocoder

mode parameter)

INPUT SELECT

While INPUT Select regularly assigns the input

source for INPUT Mode, the modulator bank in-

put is assigned here, when the vocoder is acti-

vated. Again, stereo sources like L+R are mixed

to a monophonic signal.

MODULATOR FREQUENCY OFFSET

A linear shift of the modulator bank’s central fre-

quencies against the carrier bank, results in

pitch-shifting and ”mickey mouse” effects.

CUTOFF2 creates an offset of the modulator to

the carrier bank.
