Edit notes in regions in GarageBand for iPhone
You can edit notes in green Touch Instrument regions. The editor is like a close-up version of Tracks view, showing the notes in the region as rectangular bars. When you open the editor, you can change the pitch, length (duration) and velocity of individual notes. For some instruments, you can also change the articulation of notes, or the instrument that plays the note. Notes in blue regions cannot be edited.
You can also turn off Snap to Grid to edit notes free of the grid. To learn how to turn off Snap to Grid, see Edit regions in GarageBand for iPhone.
