Logic Pro Phat FX processors
The parameters of all Phat FX processors are described in the respective sections below.
Bandpass parameters
The Bandpass unit passes the portion of a signal occupying a band surrounding the cutoff
frequency and rolls off the portions above and below that band. The Reject Mix knob lets
you restore (mix in) the signal that was not band passed at the Bandpass unit position
within the overall signal chain. This allows you to apply one or more effects to a specific
frequency range only, leaving other frequencies unchanged.
On/Off button: Enable/disable the bandpass filter.
Type pop-up menu: Choose a filter characteristic. Each option provides a different tonal
color and response to High and Low Res control values.
Low/High sliders and fields: Set the lowest and highest frequencies allowed to pass by
the filter. Frequencies outside these boundaries are cut.
The length of the horizontal orange bar represents the frequency range. The handles on
the left and right ends of the bar set the Low and High frequency values. You can move
the entire frequency range by dragging the bar. You can also drag in the numeric fields
above the bar to adjust the frequency values.
Low/High Res knobs and fields: Determine the basic sonic character of filtering
around the low and high frequencies set with the Low/High sliders. Higher Res
settings emphasize the frequency, resulting in a sharper, brighter character.
Lower Res settings result in a softer character.
Reject Mix knob: Mix in (restore) the signal that was not band passed at the Bandpass
unit position within the signal chain.
Filter parameters
The filter unit provides dozens of filter types. See Logic Pro Phat FX filter types.
On/off button: Enable/disable the filter effect.
Type pop-up menu: Choose a filter characteristic. Each option provides a different tonal
color and response to Cutoff, Drive, and Res control values.
Note: The chosen filter type can alter the names and functions of the default Cutoff,
Res, and Drive knobs.
