SweepFilter simulates a Moog-
type resonant low-pass filter. Cut-
off frequency and output level are
interpolated, and can be swept.
The performance of this filter is
high enough that it can be used as
a lowpass filter for hiss reduction.
The parameters were de-
signed to allow synthesizer-like
control of the filter. For example:
Use FC like the manual “cutoff”
knob of an analog synth – set it to
the filter frequency desired when
all modulation sources are at mini-
mum.
Use Mod as the patch destina-
tion for as many as five modulation
sources (LFO, Rand, Env,
LastNote, etc.).
Use Scale as a master depth
control for all modulation sources.
Mix 0-100% Dry/Wet ratio
Level Off, -89 to +6dB Amount of effect in the processed signal
Gain -72 to +24dB Boost/cut gain of filter
Fc 20-20000Hz Center or corner frequency of filter
Q 0.1-10.0 Q of filter
Mode LShlf, Band, HShlf Determines EQ type
The 1-Band (M) effect provides
a single band of double-precision
parametric EQ with adjustable cen-
ter frequency, Q, boost/cut and
filter type (low shelf, band, high
shelf).
