CHAPTER 7
The Parameters
INTENSITY
For the distortion curves, this intensity range is
equivalent to a gain boost of 12 decibels, in the
case of the "Digital" curve as much as 24 deci-
bels. A special feature of the VIRUS' SATURA-
TION stage is that, despite the fact that its gain
is boosted, the signal level is kept constant so
that only the tonal color or timbre of the sound
is varied.
The Effects section of the VIRUS features a fur-
ther distortion module called SATURATION. Its
design is identical to that of the DISTORTION
module discussed here, except for one major
difference: whereas SATURATION affects each
voice separately, DISTORTION processes all
voices collectively in the effects section. This
makes a huge difference in tone.

PHASER

DIR/EFF
Controls the balance of volume levels between
the direct signal and the Phaser signal: At a val-
ue of 0, only the direct signal is audible, at a val-
ue of 127, only the Phaser output signal is
audible. The values between these two ex-
tremes determine the mix of the two signals.
The pure phaser signal is generated by frequen-
cy-dependent phase shifting (PHASER Fre-
quency) and pitch modulation of the phaser's
own LFOs (PHASER Rate and Depth). Not until
the direct or dry signal (PHASER Dir/Eff) is
mixed to the wet effects signal is the typical
phaser effect generated.
DEPTH
Controls the intensity of the Phaser frequency
modulation by the LFO.

FREQUENCY
The characteristic corner frequency of the
phaser's all-pass filter. The frequencies of the
left and right sides are shifted every so slightly
to create a real stereo effect.

FEEDBACK
Controls the amount of feedback in the Phaser.
On the phaser, FEEDBACK lets you boost spe-
cific frequencies in the phase-shifted signal.
