Rectify
Full-wave rectification is a type of audio
signal processing where one half of the
signal is inverted. Rectify is the dry /
wet control for blending the incoming
signal with the rectified signal. For your
information: The rectifier stage is di-
rectly located before the filter module
within 2-pole’s signal path.
[
You can use the rectifier as pitch-doubler when
using simple waveforms as input signal.
Type Selector
LP / BP / HP
Selects the filter type:
•
The LP Lowpass cuts frequen-
cies above the cutoff point.
•
The BP Bandpass cuts fre-
quencies both below and above the cutoff point. As
a result, the sound character gets thinner.
•
The HP Highpass cuts frequencies below the cutoff
point. It is useful to thin out a sound’s bass.
Cutoff
Cutoff
controls the corner
frequency of the lowpass and
highpass filter types and the
center frequency of the band
pass. You can bring in more
movement to the sound by
modulating the cutoff fre-
quency via the LFO or the
envelope follower.
Resonance
Resonance is the emphasis around the
corner frequency. Use lower values to
give more brilliance to your sound. At
higher values, a sound gets the typical
filter character with a strong boost
around the cutoff frequency. When the
setting is raised above the center posi-
tion, the filter starts to self-oscillate producing a wave
ranging from sine to a square-like.
