System Exclusive Data

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 parameters are individually accessible by SysEx-
Parameterchange.
The pages A and B represent a Single-Program, thus a Single-Program contains 256 Bytes.
Page A (LowPage) contains Single parameters that are usefull for MIDI automation. The param-
eters of this page are additionally controllable by MIDI Control Change. The sending and recep-
tion of MIDI Control Change can be enabled or disabled by MIDI CONTROL LowPage (CONFIG
menu). When disabled (LowPage=SysEx), the VIRUS only sends and receives SysEx Parameter
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-Parameterchange
on Page A. The default setting is LowPage=Contr.
The remaining Single parameters in Page B (HiPage) are additionally controllable by MIDI Poly-
phonic Pressure (!). The send and reception of MIDI Poly Pressure can be enabled or disabled
by MIDI CONTROL HiPage (CONFIG 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 parame-
ter movements, and receives both MIDI Poly Pressure and SysEx Parameter Change on Page
B. This feature should not be used in connection with a keyboard that sends Polyphonic Pres-
sure. The default setting is HiPage=SysEx.
Page C contains Multi parameters and Global parameters. These parameters are sent and
received only by SysEx Parameter Change.
In the following, all bytes are shown in hexadecimal representation.
