MIDI from audio using Flex Pitch in Logic Pro
You can create MIDI regions from audio regions in an audio track with Flex Pitch enabled.
This “audio-to-MIDI” capability can be used to double the audio regions using a different
instrument or different effects, to modify the sound of the original audio recording, to
notate the music, and for other purposes.
Creating MIDI regions from an audio recording works best with monophonic material;
chords or polyphonic material may lead to errors in interpretation. Before creating the
MIDI regions, its a good idea to make any needed corrections to the audio after enabling
Flex. This could include timing corrections, missing or incorrectly pitched notes, and other
corrections. After creating the MIDI regions, you can make further corrections and changes
to the MIDI notes.
When you use the Create MIDI Track from Flex Pitch Data command, a MIDI region is
created for each audio region on the audio track.
