Configuring AMS (Mac OS X Only)
Audio MIDI Setup
Pro Tools recognizes the ports on your MIDI in-
terface as generic ports. With Mac OS X, you use 
Apple’s Audio MIDI Setup (AMS) utility to iden-
tify external MIDI devices connected to your 
MIDI interface and configure your MIDI studio 
for use with Pro Tools.
To configure your MIDI studio in AMS:
1 Do one of the following:
• Launch Audio MIDI Setup (located in Ap-
plications/Utilities).
– or –
• In Pro Tools, choose Setup > MIDI > MIDI 
Studio.
2 Click the MIDI Devices tab. AMS scans your 
system for connected MIDI interfaces. If your 
MIDI interface is properly connected, it appears 
in the window with each of its ports numbered.
3 For any MIDI devices connected to the MIDI 
interface, click Add Device. A new external de-
vice icon with the default MIDI keyboard image 
will appear.
4 Drag the new device icon to a convenient lo-
cation within the window.
To ensure optimum performance, do not 
change the AMS configuration while 
Pro Tools is playing back. Stop the 
Pro Tools transport before launching AMS.
