Apple Logic Pro 9 - Manual (Page 242)

Assigning Track Icons in the Track Parameter Box
Logic Pro offers high-resolution, scalable (from 128 x 128 pixels downward), and
user-definable track icons.
To assign an icon to a track
µ
Click an existing track icon in the Track Parameter box, and choose the icon you want
from the grid.
You can create your own icons for tracks. User-created icons are saved in the following
folder: ~/Library/Application Support/Logic/Images/Icons.
These icons must have the following attributes:
• 128 x 128 pixels in size
• An alpha channel for transparency
• Must be saved in the portable network graphics format (with the .png suffix)
• Must be given a filename that starts with a three-digit number
Note: If this number is identical to the number of one of the built-in Logic Pro icons, the
icon found in the user folder is given priority.
