The Virus and Sequencers
The Control Smooth mode param-
eter setting is considered a compo-
nent 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 con-
ventional 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 tim-
ing is not skewed by controller com-
mands. 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.
