instrument to exploit this data type in
the interest of putting further control-
lers at your disposal.)
. Please note that the Virus allows you
to control several PARTs via the same
MIDI channel. This means that an incom-
ing controller would collectively address
this parameter in all PARTs. This of
course defeats the purpose of routing
several of these PARTs via the same chan-
nel, which is to double up different
sounds. For this reason, the convention
in the Virus is that, when several of these
PARTs are patched through a single MIDI
channel, only the PART with the lowest
PART number is addressed by incoming
controllers; all other PARTs ignore this
data. This applies solely to sound param-
eters and not to so-called performance
controllers such as the modulation
wheel.
As an alternative to parameter control
via controller and polypressure data, you
have the conventional system exclusive
control option available (see "MIDI
Implementation" in the appendix, "The
Virus and Sequencers" on page 167). This
system exclusive control option may be
activated independently for the first two
Parameter PAGEs (under MIDI in the
CTRL menu), in which case this control
mode is the only type of remote control
option that is active – you get exclusively
system exclusive control, as it were. The
third parameter PAGE, in turn, lets you
control the parameters of the current
MULTI PROGRAM as well as global and/
or system parameters. This third PAGE is
addressed solely via system exclusive
MIDI messages. The advantage of system
exclusive control is that you can address
PARTs individually irrespective of what
their current MIDI channel assignments
may be.
You'll find a list of all controller and
polypressure assignments in the appen-
dix.
