CHAPTER 

20

The keyboard versions of the Virus

were not at all intended - after all 
there is no standard allocation for 
control data to parameters. 

To make it short: It can be very 
practical and easier on the nerves, 
to be able to activate the Local-Off-
Mode for the keyboard, while the 
pots still control only the Virus - 
and nothing else. Only if you want 
to record the control data in a 
sequencer, or definitely want to 
influence another machine with 
the Virus’ controls, does it make 
sense to send the control data 
simultaneously - or exclusively - to 
the MIDI-Out.

After having acquainted you with 
both of the Virus kb / Indigo’s 
Local-Off Modes, it is time to take a 
look at a few more of the keyboard 
version’s features.

The keyboard is not the only differ-
ence between a Virus kb / Indigo 
and a Virus without a Keyboard. 
After all the keyboard comes with 
two wheels and two pedal inter-
faces. The keyboard of the Virus kb 
is equipped with an aftertouch 
function; this feature is not avail-
able on the Virus Indigo.

The Pitch-Bend-Wheel is used 
mainly to bend the pitch, but can 
also be used to control other 
parameters via the modulation 
matrix. Pitch Bend is a bipolar con-
trol source, which means that the 
destination parameter can be 
shifted, starting from a middle 
value, either up or down. (A spring 
automatically returns the wheel to 
the middle value when you let it 
go.

This is not the case with the Modu-
lation Wheel: This wheel sends “0” 
when turned all the way down, 
and its maximum value when 
turned to the top. The destination 
parameter can only be shifted in 
one direction. The classic applica-
