Dual filter section
After (or before) crushing signal we can also filter it a bit by analogue-like (pass/reject) filters with adjustable
resonance. There’re two such units – one for each channel (left and right), connected in series with a bit crusher.
Single filter section is controlled by a following parameters:
•
Filter type
– There’re 4 types of filters we can choose from:
LP
(low pass),
BP
(band pass),
HP
(high pass) and
BR
(band reject).
OFF
position – turns
the filter off.
•
Cutoff
– Cutoff frequency for
LP
and
HP
, and center of the band for
BR
and
BP
.
•
Reso
/
B.Width
– Resonance for
LP
and
HP
, and band width for
BR
and
BP
.
•
Order
– This switch has two values: when switch set to
Pre
, signal is filtered
then decimated,
Post
– in this position, signal is first decimated and then
filtered.
Master section
This section controls the end of signal’s flow. The
Fx
knob defines the ratio between the
processed/unprocessed sound that is sent to an audio out.
Output volume
controls the final
amplification.
Link params
button works only in stereo mode.
Turning this parameter on, makes all components controllable by the knobs of only left
channel. It means that the parameters of the decimator and filters for left channel will be
assigned to their equivalents in the right channel as well. The left and right channel will be
processed individually with the same parameters.
Turning this parameter off will make processing left and right channel completely independent.
It allows to achieve very interesting stereo effects.
