Analog Boost - Access VIRUS CLASSIC User Manual

Mode Description
SHAPER
Sine characteristic curve with several wave cycles. With the Shaper, you
can drastically warp signals. In some cases, the results are similar to the
spectra of linear frequency modulations.
RECTIFIER
Continuous rectification of the signal; this type of distortion is independent
of the given level.
BIT REDUCER
Continuous reduction of the digital signal's bit depth; generates digital
quantization noise.
RATE REDUCER
Continuous reduction of the digital sampling rate; generates digital aliasing.
LOW PASS
-pole low-pass filter for moderate processing of high frequencies.
HIGH PASS
1-pole high-pass filter for moderate processing of low frequencies.
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 decibels. A special feature of the Virus' SATURATION 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 further 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.

Analog Boost

This effect produces the typical bass punch on analog synthesizers, and with the corresponding
TUNE setting you can emphasis the punch in the mid frequencies or even lower the treble frequen-
cies. In its mild form ANALOG BOOST is suitable for almost all sounds, collaborates well with the
distortion section, and if necessary can be set to extreme values.
