VIRUS MIDI SYSTEM EXCLU-
SIVE IMPLEMENTATION
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 parameters
of this page are additionally controllable
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 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 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.
The default setting is
HiPage=SysEx.
