3 Click the More Information arrow to expand
the dialog, then enable the appropriate MIDI
channels (1–16) for the Transmits and Receives
options. (These determine which channels the
device will use to send and receive MIDI.)
4 Click the device image. The window expands
to show images for various MIDI devices (such
as keyboards, modules, interfaces, and mixers).
Select an icon for your device.
5 Select a device image and click Apply.
6 Close the AMS window to quit the AMS appli-
cation.
The device names you enter appear as MIDI in-
put and output choices in Pro Tools.
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).

To use your own custom icons, you can
place TIFF image files in /Library/
Audio/MIDI Devices/Generic/Images, and
they will appear as choices in the AMS
device window.
To ensure optimum performance, do not
launch the Pro Tools application while run-
ning AMS. Quit the AMS application first,
then launch Pro Tools.
