Correction Amount
The amount of pitch change is indicated in the horizontal bar display. If you keep a
close eye on this display, you can use it for two important tasks: To better understand
the inner workings of the algorithm works, and adjust the Response accordingly. You
can also use the display when discussing (and optimizing) the vocal intonation with a
singer during a recording session.
Automation
As with almost all Logic plug-ins, Pitch Correction can be fully automated. This means
that you can automate the Scale and Root parameters to follow the harmonies of the
song. Simply select the Touch or Write automation modes for the track, and change the
Scale and Root parameters by key during playback. Depending on the quality of the ori-
ginal intonation, setting the key Scale might suffice. Weaker intonations might need
more significant changes to the Scale and Root parameters.
Note: The keys of the scale can’t be switched by MIDI notes.
SubBass
This plug-in generates frequencies below those in the original signal—in other words
an artificial bass.
Warning: This process is known as a loudspeaker killer! Choose moderate monitoring
levels, and never try to play back sub-bass frequencies with loudspeakers which aren’t
capable of doing so. Never try to force a loudspeaker to output these frequency bands
with an EQ.
