Quantize the note pitch in the Piano Roll Editor in Logic Pro for iPad
Scale Quantize in Logic Pro for iPad applies quantization to the pitch of notes in a MIDI region. Notes are shifted vertically to conform to a particular scale and key. This is especially useful when you want to reuse a repeating pattern of notes but transpose them to a different key.
Any selected note that doesn’t exist in the chosen key and scale is shifted to the nearest note of that scale. For example, if you have F notes in your region and set the key to D and scale to Major, every F note is shifted up a semitone to F#.
