CHAPTER 6
Concept and Operation
OPERATING MODES
In the Virus you can select from two basic oper-
a t i n g m o d e s , S I N G L E M O D E a n d M U LT I
MODE.
In SINGLE MODE, the Virus is able to generate
a single sound program only. All 32 voices, all
effects and all control features (with the excep-
tion of the MULTI button) function in conjunc-
tion with this one sound program. You might
say a SINGLE program is a combination of all
functions and effects that determine the sound
of the Virus. In other words: A SINGLE program
is a ”sound” of the Virus, that can be stored and
recalled.
The Virus provides access to 1024 SINGLE
sounds. Next to the 256 RAM sounds (Bank A
and Bank B), you have six banks available with
a total of 768 factory sounds. These banks, C to
H, are stored in the FLASH ROM and can not be
overwritten via STORE.
The MIDI receive channel in SINGLE MODE is
the Global Channel. You can change the Global
Channel in the CTRL menu.
In MULTI MODE, the Virus can combine up to
sixteen (SINGLE) sound programs, among
which the maximum available number of 32
voices are allocated dynamically. All simultane-
ously available sounds can be manipulated in
real-time; for this purpose the control panel en-
ables you to switch among the sixteen so-
called PARTS.
In MULTI MODE, the actual sound parameters
are augmented with other functions that deal
with how the involved SINGLE programs are
structured or organized. These include the vol-
ume levels of the single programs, their MIDI
channels, output assignments, etc.
THE MULTI-SINGLE MODE
While being in MULTI Mode, you’re unable to
change the SINGLE programs directly, which
would admittedly be a handy option when
you’re working with a sequencer. This is why
the Virus features MULTI SINGLE mode, which,
strictly speaking, is more an alternative view of
MULTI mode rather than a further mode in its
own right.
Activate MULTI SINGLE mode by pressing the
MULTI and SINGLE buttons simultaneously.
The name of the selected MULTI program will
disappear and instead you’ll see the name of
the SINGLE program for the selected PART.
Now you can page or scroll through the 16
PARTs using the PART buttons and select a
SINGLE program for every channel. You can
process the currently selected PART or, more
accurately, edit its sound, using the control fea-
tures. The menus let you access the usual SIN-
GLE parameters. You’ll always see the number
of the selected PART on the upper left in the
display. The PART buttons don’t actually
change sounds, they simply set the user inter-
face of the Virus to the desired PART. Irrespec-
tive of the given setting, all PARTs can be
controlled simultaneously via MIDI. Conse-
quently, MULTI SINGLE mode, which makes
