ACCESS VIRUS OS4

The parameters of the VIRUS vocoder

 

OSC-HOLD    This setting is iden-

tical to ”OSC” although the hold-
mode (which also is available at 
COMMON/KeyMode) is activated.

 

NOISE     White noise is used as 

the carrier. The oscillator section is 
disabled.

 

IN    (L / In L+R / In R / Aux L ...) 

The analog inputs or the aux-sends 
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 (Default: 0 (middle)) OSC 
VOL

 adjusts the output level of the 

vocoder. This is independent of the 
signal source (which can be 
assigned using the vocoder mode 
parameter)

INPUT SELECT (in the Edit menu) 
While INPUT Select regularly 
assigns the input source for INPUT 
Mode, the modulator bank input is 
assigned here, when the vocoder is 
activated. Again, stereo sources 
like L+R are mixed to a monopho-
nic signal. 

Vocoder Band Quantity (Knob: FIL-
TER

 RELEASE) It is possible to con-

trol the number of filter bands 
here between 1 and 32. This param-
eter changes the sonic complexity 
of the sound, by using more or less 
filter bands. Less filter bands result 
in a typical vocoder sound. More 
filter bands increase the quality of 
the signal’s reproduction (e.g. how 
easily you can ”understand” a 
vocoded voice). The Virus’ polyph-
ony might vary depending on the 
number of active filter bands.
