VIRUS CLASSIC MANUAL 85
The Parameters
To reiterate the point, the amount of distortion, intensity of the DSP effects, and the cutoff frequen-
cies of the 1- pole filter are controlled via the OSC VOL knob.
FILTER-1 ENV POLARITY
Switches back and forth between positive (POS) and negative (NEG) ENV AMOUNTs for Filter-1 (see
appropriate section).
FILTER-2 ENV POLARITY
Switches back and forth between positive (POS) and negative (NEG) ENV AMOUNTs for Filter-2 (see
appropriate section).
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.
BITREDUCER
Continuous reduction of the digital signal’s bit depth; generates digital
quantization noise.
RATEREDUCER
Continuous reduction of the digital sampling rate; generates digital aliasing.
RATE+FLW
The RateReducer with keyfollow; the sampling rate follows the played
pitch.
LOWPASS
1-pole low-pass filter for moderate processing of high frequencies.
LOW+FLW
The low-pass filter with keyfollow; the cutoff frequency follows the played
pitch.
HIGHPASS
1-pole high-pass filter for moderate processing of low frequencies.
HIGH+FLW
The high-pass filter with keyfollow; the cutoff frequency follows the played
pitch.
