Naming a new MIDI device
 For Manufacturer and Model names, AMS 
refers to one or more files with the suffix 
“.middev” in the directory Root/Library/
Audio/MIDI Devices. Pro Tools installs a 
file that contains information for many 
commercially available MIDI devices, 
named “Digidesign Device List.middev.” If 
the Manufacturer or Model names for any of 
your external MIDI devices is not available 
in the AMS Manufacturer and Model pop-up 
menus, you can add them by editing the 
.middev file in any text editor (such as 
TextEdit).
