Set signal flow order through the Ultrabeat filter and
distortion unit
The output signals of both oscillators, the ring modulator, and the noise generator are sent
to the central Filter section (if not bypassed with the various Signal Flow buttons). The
Filter section offers a multimode filter and a distortion unit. Sounds are passed through the
filter and distortion unit as determined by the direction of the arrow found in the center of
the filter section.
• In Logic Pro, 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).
Logic Pro Ultrabeat distortion circuit
The Distortion circuit provides either a bit crusher or distortion effect.
The bit crusher reduces the digital resolution of the sound, measured in bits, achieving an
intentionally digital coloration of the sound. The distortion effect is modeled on an analog
distortion unit, which distorts the sound by overdriving the level.
Both methods lead to distortions that are as tonally divergent as the two approaches.
Distortion offers a more analog tone while the bit crusher sounds unmistakably digital.
Note: The arrow in the Filter section determines whether the Distortion circuit is inserted
before or after the multimode filter (see Set signal flow order through the Ultrabeat filter
and distortion unit).
