tion for the Modulation Wheel is to 
blend in vibrato for a sound. As a 
standard it is usually assigned to 
MIDI-Controller Nr. 1 (“Modula-
tion”). Of course the Modulation 
Wheel can control other things 
instead of vibrato, e.g. the opening 
of a filter. As a matter of fact the 
modulation wheel can be used to 
control several parameters at the 
same time, because it can be 
assigned to different modulation 
destinations via the modulation 
matrix - by the way, the same 
applies to the other control fea-
tures. These multiple assignment 
capabilities enable you to create 
very complex sound changes, one 
might call them Sound-”Mor-
phing.”
 
The Virus kb / Indigo allows you 
to freely choose the controller that 
the Modulation Wheel sends - just 
in case you need it (Parameter KEYB 
MODWHEEL (Off, 1...127)). The stan-
dard, (and the factory preset) for 
the Modulation Wheel is - as men-
tioned above - MIDI-Controller 1. 
You could control any of the Virus’ 
parameters by assigning the wheel 
to the corresponding controller. 
Although this would work, we 
strongly advise against doing so. If 
you assign a different controller 
than “1” to the Modulation Wheel, 
the Virus’ software no longer rec-
ognizes the Modulation Wheel as 
such, and connections in the mod-
ulation matrix, (ASSIGN-Menue) 
that use the modulation wheel as 
the source of modulation no 
longer have any effect. The right 
way to do it, which we strongly 
recommend, is to leave the Modu-
lation Wheel on Controller 1, and to 
select the corresponding modula-
tion destination for the wheel in 
the matrix. Then the adjustments 
are also valid for each sound, and 
everything works the way it is sup-
posed to.
Let us turn to the two pedal inter-
faces: They enable you to connect 
switch pedals (on/off) or control 
pedals (constant control signal). 
You can choose a MIDI-Controller 
for the pedals (Parameter: KEYB 
PEDAL 1 or 2 (Off, 1...127)). Standard 
are Controller 64 (hold or sustain 
pedal, the note played is held) and 
7 (Channel- or MIDI-volume, the 
volume of the sound played.) Just 
as with the Modulation Wheel, the
