Logic Pro X: Change the pitch of notes in the Piano Roll Editor
You can change the pitch of selected notes in the Piano Roll Editor. Changing the pitch lets you transpose parts to a different key or harmonize a melodic line.
When you drag a note, its current position and pitch are shown in a help tag. The deviation from the starting pitch is shown in semitone steps at the bottom left of the help tag. The starting pitch appears in the info display of the Piano Roll Editor.
