LOGIC INSTRUMENT (ARRANGE WINDOW) ICONS
Versions of Apple Logic Pro from 6 onwards allow you to make your own instrument icons for the arrange window. These are a few that I have created and have made freely available. The saxophones are from photographs of my own instruments.
Download and place these in the icons folder (see below). The background you see here will appear transparent in Logic. The numbered icons can be placed straight in the folder, the named ones need to be renamed with a number below 325.
To download on Mac [CTRL]+click on the image, or just drag the icon to the desktop.
