8 Click OK.
You can configure additional MIDI control sur-
faces (for a total of four) by repeating the above
steps. Make sure that none of the control sur-
faces are assigned to the same MIDI source and
destination ports or channels in the Pro Tools
Peripherals dialog.
Enabling Active in Background
(Mac OS 9 Only)
If you are using the Mackie HUI, make sure Ac-
tive in Background is selected in the Pro Tools
Operations menu.
Enabling Input Devices
(Macintosh Only)
On the Macintosh, you must enable the MIDI
control surface as an input device in Pro Tools.
To enable an input device:
1 Choose MIDI > Input Devices.
2 Select the MIDI control surface.
3 Click OK.
When you add a device in Apple Audio MIDI
Setup on Macintosh OS X, or in OMS Setup on
Macintosh OS 9, while Pro Tools is running, it
will be automatically enabled as an input de-
vice. If you want to prevent MIDI data from a
control surface reaching Pro Tools, you can dis-
able a control surface as an input device.
Testing Connections
Move a fader or knob on your MIDI control sur-
face, and the corresponding on-screen control
should move. If your system does not seem to be
responding correctly, first check all MIDI con-
nections and settings. If there is still a problem,
repeat the installation and configuration steps.
General Information for All
MIDI Control Surfaces
Pro Tools Display of Banks
In the Pro Tools Mix window, the channel strips
corresponding to a “bank width” of faders are
highlighted in color. The number of faders in a
bank will correspond to your control surface
type, and to the number of channels specified in
the #Ch’s pop-up menu.
Each control surface choice in the Peripherals
dialog has an identifying color associated with
it. Pro Tools places a colored outline around the
channel strips in any bank that is the control fo-
cus of your control surface. If you enable addi-
tional control surfaces, Pro Tools will outline
the channel strips with the color that corre-
sponds to the numbered control surface (1–4) in
the Peripherals dialog.
