Use Ultrabeat’s filter Cutoff parameter
mm
Rotate the Cutoff Frequency (Cut) parameter to control the brilliance or determine the center
frequency of the signal.
••
In a lowpass filter, the higher the cutoff frequency is set, the higher the frequencies of signals
that are allowed to pass.
••
In a highpass filter, the cutoff frequency determines the point where lower frequencies are
suppressed, with only upper frequencies allowed to pass.
••
In a bandpass/band-rejection filter, the cutoff frequency determines the center frequency for
the bandpass or band-rejection filter.
Use Ultrabeat’s filter Resonance parameter
mm
Rotate the Resonance (Res) parameter to emphasize or suppress portions of the signal above or
below the defined cutoff frequency, or to determine the width of the band that surrounds the
cutoff frequency.
••
In a lowpass filter, Resonance emphasizes or suppresses signals below the cutoff frequency.
••
In a highpass filter, Resonance emphasizes or suppresses signals above the cutoff frequency.
••
In bandpass/band-rejection filters, resonance determines the width of the frequency band
that surrounds the center frequency (set with the Cutoff Frequency parameter).
Set the signal flow order through Ultrabeat’s filter and distortion unit
The output signals of both oscillators, the ring modulator, and the noise generator are sent to
Ultrabeat’s central Filter section (if not bypassed with the various Signal Flow buttons). The Filter
section offers a multimode filter and a distortion unit.
mm
Click the arrow to change the signal flow order between the following:
••
First the Distortion unit, then the Filter circuit (arrow pointing up)
••
First the Filter circuit, then the Distortion unit (arrow pointing down).
Multimode filter
Sounds are passed
through the filter and
distortion unit as
determined by the
direction of the arrow
found at the equator of
the filter section.
