CHAPTER 5
Concept and Operation

Compare mode lets you hear the unedited
sound that was originally stored in this memory
slot. Press EDIT or UNDO repeatedly to switch
back and forth between the Compare sound
and the edited sound so that you can - sur-
prise, surprise – compare the two sounds. Use
the PARAMETER/BANK buttons and the VALUE
buttons to step through the bank and program
numbers of the Compare sound. This lets you
search for a new memory slot for the edited
sound and, at the same time, hear the sound
that you will overwrite. The edited sound is not
modified or overwritten during this process.
Press STORE to do just that to the edited sound
– store it. Press MULTI or SINGLE to quit the
STORE process and/or exit Compare mode.

UNDO

Pressing the Undo button cancels the last pa-
rameter change you have made to the current
SINGLE program – it returns to the previous
state. As the following example shows, the UN-
DO algorithm has a degree of intelligent: If for
instance the Cutoff control is turned up continu-
ously from 0 to127, pressing the Undo button
will take it right back to 0 (and not 126, although
the last change was actually from 126 to 127).

Pressing the UNDO button again performs a
REDO, i.e. it cancels the UNDO (in the above
example Cutoff would revert to 127). Repeated-
ly pressing the UNDO button alternates be-
tween the two states.

The UNDO function can also be called up after
the Virus has received a program change mes-
sage – whether via MIDI or on the Virus itself. In
Single mode, the last edited sound is restored –

so it is not lost even after several program
change messages (as long as none of the other
programs are edited in any way). In Multi Single
mode, all edited sounds can be restored even
after changing to another Multi program.

In Multi-Single-Mode the last edited patch of
the current part is being restored. Even after a
Multi-Program-Change all 16 edit buffers can
be recalled.

THE MODULATION MATRIX

AND SOFT KNOBS

CREATING MODULATION CONFIGU-
RATIONS VIA ASSIGN

It is generally a good idea for a synthesizer to
allow users to define modulation paths them-
selves i.e. to be able to connect any modulation
source with any destination. Sometimes you
might have a wild idea which would not be pos-
sible using the more directly available “hard-
wired” paths – so a flexible modulation matrix is
a real bonus for creative users. The Virus mod-
ulation matrix can be programmed using the
