The Virus and Sequencers
The Control Smooth mode parameter
setting is considered a component
part of a SINGLE sound and is
thus stored with it.
Step sequencers let you assign a
new cutoff value for every note. You
can create the same effect on a conventional
sequencer. To this end, all
you have to do is program a cutoff
controller in the sequencer for every
note in the arrangement. However,
be aware that conventional
sequencers can throw a spanner in
the works: If the timing of this type
of controller coincides precisely
with the timing of a note, the
sequencer will first send the note
command so that the overall timing
is not skewed by controller commands.
For the purposes of our
example, this means that the new
cutoff value doesn’t arrive until just
after the note has been played. This
can generate incidental artifacts.
We recommend that you record the
controllers separately to a track
other than the one containing the
notes of a given sequence (make
sure that the track addresses the
same MIDI channel) and that to
assign a touch of predelay to this
track (e.g. set Track Delay to -1).
Then the cutoff value is updated
just before the new note arrives.
Incidentally, this phenomenon is
not unique to the Virus, it is a
design-related ”flaw” inherent in
all synthesizers.
