SYSTEM EXCLUSIVE DATA

í
System Exclusive Imple-
mentation
The Parameters of the VIRUS are orga-
nized 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 parameters 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 (CTRL menu). When disabled
(LowPage=SysEx), the VIRUS only sends
and receives SysEx Parameter Change on
Page A. When enabled (Low-
Page=Contr), the VIRUS sends MIDI Con-
trol Change on parameter movement,
and receives both MIDI Control Change
and SysEx-Parameterchange on Page A.
s The default setting is Low-
Page=Contr.
The remaining Single parameters in Page
B (HiPage) are additionally controllable
by MIDI Polyphonic Pressure (!). The send
and reception 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 keyboard that
sends Polyphonic Pressure.
