Logic Pro Ultrabeat filter section
The Ultrabeat multimode filter can dramatically, or subtly, alter the timbre of your drum
sounds.
Filter parameters
Filter (On/Off) button: Turn the entire Filter section on or off. Deactivating the Filter
section makes it easier to hear adjustments to other sound parameters, as the filter
always heavily affects the sound. If the Filter label is red, the filter is engaged. If gray,
the filter is disabled.
Filter Type buttons: Switch the filter between lowpass, highpass, bandpass, or band-
rejection filter types.
Filter Slope buttons: Switch the filter between different slopes.
Cutoff and Resonance knobs: Rotate to set the cutoff/center frequency and resonance/
bandwidth of the filter.
Mod and via pop-up menus: Choose the modulation source (and via source) for the
Cutoff and Resonance parameters. See Mod and via modulations in Logic Pro Ultrabeat.
Set the Ultrabeat filter type
The filter can operate in several modes, allowing specific frequency bands to be filtered
(cut away) or emphasized.
In Logic Pro, to select a filter type, click one of the following buttons:
LP (lowpass): This filter type allows frequencies that fall below the cutoff frequency
to pass. When set to LP, the filter operates as a lowpass filter. The slope of the filter
can be set to 12 or 24dB/octave in LPmode.
HP (highpass): This filter type allows frequencies above the cutoff frequency to
pass. When set to HP, the filter operates as a highpass filter. The slope of the filter
can be set to 12 or 24dB/octave in HPmode.
BP (bandpass): The frequency band directly surrounding the center frequency
(set with the Cutoff knob) is allowed to pass. All other frequencies are cut. The
Resonance parameter controls the width of the frequency band. The bandpass
filter is a two-pole filter with a slope of 6 or 12dB/octave on each side of the center
frequency of the band.
