Handling Midi Parameter Control - Access Virus Rack XL User Manual

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 parameters and not
to so-called performance controllers such as
the modulation wheel.
As an alternative to parameter control via con-
troller and polypressure data, you have the con-
ventional system exclusive control option
available, see "MIDI Implementation" in the ap-
pendix ["System Exclusive Data" on page 158].
This system exclusive control option may be
activated independently for the first two Param-
eter 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 con-
trol the parameters of the current MULTI PRO-
G R A M a s w e l l a s g l o b a l a n d / o r s y s t e m
parameters. This third PAGE is addressed sole-
ly via system exclusive MIDI messages. The ad-
vantage 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 polypres-
sure assignments in the appendix. ["Parameter
Descriptions" on page 162]

HANDLING MIDI PARAMETER
CONTROL
If you have configured your MIDI system in ac-
cordance with the instructions in the previous
section, you may activate the sequencer's re-
cording mode and record the knob and button
movements as you see fit. Check the Event or
List editor of your sequencer to see if the re-
cording operation was successful.
Good-to-know info: Do not record knob and
button movements to the same track that con-
tains the notes of any given passage. Instead,
use a new track that sends its data to the same
MIDI output and channel as the track containing
the notes. Although the sequencer merges
these two data streams internally, separating
the two tracks makes it easier for you distin-
guish between the information that they con-
tain. Besides, you're thus able to edit and copy
the recording of t knob and button movements
without affecting the actual notes on the other
track.
If you wanted to take this an extreme, you could
record the movements of every knob and but-
ton to a separate track. Although this sounds
like a classic case of overkill, it can facilitate the
process of editing the recorded sequences:
Bear in mind that the sequencer doesn't indi-
cate the parameters addressed via the control
features of the Virus by their names; instead, it
indicates merely the controller and/or polypres-
sure numbers. If you split up these control fea-
tures by recording them to different tracks and
giving these tracks names that give you an idea
of what they contain, you'll find it much easier
to work with these tracks.
