CHAPTER

The Vocoder of the VIRUS

The vocoder can also be controlled 
by any part of the multimode. If 
more than one part of the multi-
mode contains an activated 
vocoder, only the vocoder of the 
part with the lowest part number 
is active.

The vocoder takes a lot of comput-
ing power. This reduces the maxi-
mum number of voices dependent 
on the number of vocoder bands 
used. A vocoder with 32 bands 
takes approximately 4 voices away, 
although the vocoder only starts to 
reduce the number of voices when 
there is an audio signal at the 
vocoder input. 10 seconds after the 
signal is diminished, the VIRUS 
”frees” the voices again to get back 
the maximum polyphony.

As mentioned before, the whole 
filter section is exchanged to the 
vocoder, parameters, parameters 
like saturation or the filter routing 
are not available anymore.

If you would like to use the vocoder 
as an external effect device, 
choose one external input in the 
VOCODER MODE parameter page 
(modulator signal) and the carrier 
signal by the INPUT SELECT page.

A similar task has to be performed 
to use several multimode parts to 
feed the vocoder. Use OUTPUT 
SELECT (OutSel) within the desired 
multimode patches to route them 
to the auxiliary sends. Then select 
these auxiliary sends in the 
VOCODER MODE and INPUT page. 
Isn’t that easy?

The auxiliary sends of more than 
one part are mixed automatically 
(similar to a mixing desk). There-
fore, a whole drum track (which 
consists of several multiparts for 
several instruments) can be used 
at once to drive the vocoder’s in. 
Using FILTER BALANCE you can bal-
ance the level of the original sig-
nal.

The effect section (chorus, delay) 
and the output selection can be 
used in a vocoder patch.
