The Virus and Sequencers
Side effect: This analysis of radical
parameter changes can't cope with
jumps that occur in rapid succession.
NOTE Adaptive Control Smoothing
works continuously, but jumps when a
new note is played.
Application: Both continuous as well as
sudden parameter changes may be
implemented, whereby the jumps are
always inserted at the beginning of a
new note. Consequently, this option is
well-suited when you want to control
sounds via a step sequencer.
Side effect: When you're playing poly-
phonically, parameter jumps also affect
notes that were played previously and
are still sounding when a new note is
played.
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 cre-
ate 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 arrange-
ment. However, be aware that conven-
tional 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 control-
ler 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 synthesiz-
ers.
