The LFOs
lend it a certain vitality. The key to
many great sounds are these types
of minimal modulations.
many great sounds are these types

You may have gathered that the
LFOs of the Virus are polyphonic:
If several notes are played simulta-
neously, these are controlled by
dedicated LFOs, each with a
slightly varied rate. This effect liv-
ens up the sound of chords, espe-
cially when they are sustained. To
enhance this effect, activate the
LFO 1 KEY FOLLOW in the LFO-EDIT-
Menu.

This function enables you to con-
trol the rate of the LFOs via the
pitch, or more accurately, via the
MIDI note number, so that higher
notes generate faster LFO rates. As
result, when you press and hold
several notes you will hear all kinds
of substantially different periodic
fluctuations.

Finally, the LFOs can also be used
as additional envelopes. The con-
trol feature for this effect is the
ENV MODE button. When you
press this button, two things
occur: For one, the LFO no longer
initiates its cycles periodically, but
only once at and in sync with the
as additional envelopes. The con-
trol feature for this effect is the
ENV MODE button. When you
press this button, two things
occur: For one, the LFO no longer
initiates its cycles periodically, but
only once at and in sync with the
start of a note, and for the other,
the active range of the LFO is
switched from bipolar (in both
directions from the zero position)
to unipolar (from zero in one direc-
tion only). Please note that this
applies to the modulation target
but not the modulation intensity.
Here you can still determine a
value in the entire bipolar range.

This effect is especially prominent
when used in conjunction with the
sawtooth wave, which enables a
fade-out type of effect (when you
dial in a positive AMOUNT value)
or a volume-swell type of effect
(negative AMOUNT) for the avail-
able modulation targets. Using the
LFO Curve parameter located in
the LFO EDIT menu, you can have
the ”ramp” rise or fall exponen-
tially. If you choose a triangle for
your waveshape, the device will
generate an ascending phase
(attack) and a descending phase
(decay). LFO Curve also lets you
determine the temporal relation-
ship between attack and decay; in
other words, their respective rates..

RATE pot.
