Key commands in Logic Remote on iPhone overview
You can perform nearly every function in GarageBand with a key command, greatly accelerating your workflow. In Logic Remote, you can use existing key commands or search for key commands and assign the functions that you use most often to individual buttons. You do this in Key Commands view.
At the bottom of Key Commands view are default key commands that remain visible when you swipe between pages. You can replace these key commands with your own.
Open Key Commands view
Rotate the iPhone to landscape orientation.
Tap the View button in the control bar, then tap Key Commands.
Use a key command
Tap an existing key command with one finger or with two fingers when in key command editing mode.
Use a key command repeatedly
Touch and hold an existing key command.
While this technique does not suit all key commands, you may find it useful for navigation and zoom commands, for example.
