CHAPTER 

24

Appendix

The Parameters of the VIRUS are 
organized in three so-called pages 
A, B and C. Each page contains 128 
parameters, addressed by numbers 
from 0 to 127. Each parameter is 
represented by one byte with a 
maximum value of 127. All parame-
ters are individually accessible by 
SysEx-Parameterchange.

The pages A and B represent a Sin-
gle-Program, thus a Single-Pro-
gram contains 256 Bytes.

Page A (LowPage) contains Single 
parameters that are usefull for 
MIDI automation. The parameters 
of this page are additionally con-
trollable by MIDI Control Change. 
The sending and reception of MIDI 
Control Change can be enabled or 
disabled by MIDI CONTROL Low-
Page (CTRL menu). When disabled 
(LowPage=SysEx), the VIRUS only 
sends and receives SysEx Parame-
ter Change on Page A. When 

enabled (LowPage=Contr), the 
VIRUS sends MIDI Control Change 
on parameter movement, 

and receives both MIDI Control 
Change and SysEx-Parameter-
change on Page A.

The remaining Single parameters 
in Page B (HiPage) are additionally 
controllable by MIDI Polyphonic 
Pressure (!). The send and recep-
tion of MIDI Poly Pressure can be 
enabled or disabled by MIDI CON-
TROL HiPage (CTRL menu). 

When disabled (HiPage=SysEx), 
the VIRUS only sends and receives 
SysEx Parameter Change on Page 
B. When enabled (HiPage=PolyPrs), 
the VIRUS sends MIDI Poly Pressure 
on parameter movements, and 
receives both MIDI Poly Pressure 
and SysEx Parameter Change on 
Page B. This feature should not be 
used in connection with a key-
board that sends Polyphonic Pres-
sure.
