REAKTOR SPARK – 23
The S
tatic
c
utoFF
K
nob
is a main parameter of the Filter section. It determines which frequen-
cies are filtered out of the signal and which ones are passed on to the output of this section.
The
S
tatic
c
utoFF
K
nob
is used as a reference value for the cutoff frequency of both parts
of the multi-mode filter. The difference between the cutoff frequencies of the two filters is
controlled by the
S
plit
K
nob
.
Filters not only filter out frequencies, but also enhance others. The r
eSonance
K
nob
controls
the amount of resonance of both filters, that is, the amount of the signal enhancement at
cutoff frequency. High values yield a sound that resembles a sinus tone.
Depending on the setting of the
F
ilter
t
ype
K
nob
, one can filter out different frequencies in
relation to the cutoff frequency. A lowpass filter (LP) lets frequencies below the cutoff fre-
quency pass, a highpass filter (HP) lets frequencies above the cutoff frequency pass, and a
bandpass filter (BP) lets frequencies within a certain distance from the cutoff frequency pass.
The setting of the
F
ilter
t
ype
K
nob
determines the type for both filters.
The F
ilter
S
lope
K
nob
controls how much the frequencies outside of the filter’s “pass”-interval
are damped before the signal is passed to the Shaper section. Turn the F
ilter
S
lope
K
nob
to
the left for weaker filtering, to the right for stronger filtering. The Filter section consists of
two serially connected filters, each damping 12 dB/octave. The
F
ilter
S
lope
K
nob
determines
if the output signal of only one or both filters is used for the Shaper section input.
The
F
ilter
t
racK
K
nob
sets the tracking amount of the filter cutoffs. Since digital instruments
seem to sound too bright when notes in the higher registers are played, using the F
ilter
t
racK
K
nob
helps you counteract that so the cutoff frequency of the filter depends on the note that
is played. When the F
ilter
t
racK
K
nob
set to 0.0, no tracking with the key position takes place,
and when set to 1.0, the key position relative to C3 is fully added to the filter cutoff. For
sounds that don’t exhibit an excessively bright timbre in the upper registers, turn the
F
ilter
t
racK
K
nob
to a value between 0.0 and 1.0.
The color of the Filter section’s output signal can be further controlled with the F
ilter
FM
K
nob
. This parameter controls how much the filter cutoff frequency is modulated by the filter
input signal.
