Use Ultrabeat’s lter Cuto parameter
m Rotate the Cuto Frequency (Cut) parameter to control the brilliance or determine the center
frequency of the signal.
•
In a lowpass lter, the higher the cuto frequency is set, the higher the frequencies of signals
that are allowed to pass.
•
In a highpass lter, the cuto frequency determines the point where lower frequencies are
suppressed, with only upper frequencies allowed to pass.
•
In a bandpass/band-rejection lter, the cuto frequency determines the center frequency for
the bandpass or band-rejection lter.
Use Ultrabeat’s lter Resonance parameter
m Rotate the Resonance (Res) parameter to emphasize or suppress portions of the signal above or
below the dened cuto frequency, or to determine the width of the band that surrounds the
cuto frequency.
•
In a lowpass lter, Resonance emphasizes or suppresses signals below the cuto frequency.
•
In a highpass lter, Resonance emphasizes or suppresses signals above the cuto frequency.
•
In bandpass/band-rejection lters, resonance determines the width of the frequency band
that surrounds the center frequency (set with the Cuto Frequency parameter).
Set the signal ow order through Ultrabeat’s lter 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 oers a multimode lter and a distortion unit.
m Click the arrow to change the signal ow 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).

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.
