Exciter parameters
• Frequency field: Drag vertically to set the cutoff frequency of the highpass filter.
The input signal passes through the filter before (harmonic) distortion is introduced.
• Frequency display: Shows the frequency range used as the source signal for the
excite process. You can drag the green line or handle to set the cutoff frequency.
• Dry Signal button: Turn on to mix the original (pre-effect) signal with the effect signal.
Turn off to hear only the effect signal.
• Harmonics knob and field: Set the ratio between the effect and the original signals.
If the Dry Signal button is turned off, this parameter has no effect.
Note: In most cases, it is preferable to select higher Frequency and Harmonics
values, because human ears cannot easily distinguish between the artificial and
original high frequencies.
• Color 1 and 2 buttons: Turn on Color 1 to generate a less dense harmonic distortion
spectrum. Color 2 generates more intense harmonic distortion.
Note: Color 2 also introduces more intermodulation distortions, which can result in
unpleasant artifacts.
SubBass
Logic Pro SubBass overview
SubBass generates frequencies below those of the original signal, resulting in artificial
bass content. The simplest use for SubBass is as an octave divider, similar to octaver
effect pedals for electric bass guitars. Whereas such pedals can only process a
monophonic input sound source of clearly defined pitch, SubBass can be used
with complex summed signals as well.
SubBass creates two bass signals, derived from two separate portions of the
incoming signal. These are defined with the High and Low parameters. See
Logic Pro SubBass parameters.
WARNING: Using SubBass can produce extremely loud output signals. Choose moderate
monitoring levels, and only use loudspeakers that are actually capable of reproducing the
very low frequencies produced. Never try to force a loudspeaker to output these frequency
bands with an EQ.
