How do I use the custom I/O labels in Logic?

• Go to Logic's Mix menu at the top of the screen and select "I/O Labels..."
• There are several columns: Channel, Provided by Driver, User, Long, & Short.
• To use the labels provided by the Ensemble:
  • Click the button in the Provided by Driver column.
• To enter your own custom label:
  • Click the button in the User column.
  • Double click the "-" in the Long column, type in a new name, then press Return on your Apple keyboard
