The Power LED indicator lights when the MIDI I/O is powered on. The MIDI I/O can be powered by USB or by an optional external power supply. There is no On/Off switch on the MIDI I/O. The MIDI I/O is always on when it is receiving power, either from your computer over USB or from an external power supply.

Alternate Power
If you want to use the MIDI I/O without con- necting it to your computer, you can use any 9–12 Volt DC power adapter, 500 mA (Tip +/Ring –) for power. When used in this way, the MIDI I/O will only function in MIDI Thru mode.
Typically, you will not need to use an external power supply when the MIDI I/O is connected to your computer, since the MIDI I/O is pow- ered over USB from your computer. However, if you want to use the MIDI I/O in MIDI Thru mode without a computer, or if it is connected to an unpowered USB hub, you will need to use an external power supply.
Do not attempt to use one or more unpow- ered MIDI I/O units on an unpowered USB hub.
LED Startup Sequence
The MIDI I/O’s internal firmware will load when the MIDI I/O is powered on (either from USB or an external power supply). You will see an LED startup sequence and the Power LED will light. This LED startup sequence indicates that the in- ternal firmware has successfully loaded. When powered on, the MIDI I/O is in MIDI Thru mode.

You will only need to run the Digidesign MIDI I/O Setup application once. After that, use the Hardware Wizard to set up any additional MIDI I/Os that are added later.
To install the MIDI I/O drivers:
1 Connect your MIDI I/O to any available USB port on your computer. See “Connecting USB” on page 8.
2 Launch the Digidesign MIDI I/O Setup appli- cation from your Pro Tools Installer CD-ROM.

MIDI Time Stamping • Connect MIDI I/O to an external power supply (9–12 Volts DC, 500 mA; Polarity: The MIDI I/O is equipped with MIDI Time Tip = Plus, Ring = Minus). Stamping capabilities. MIDI Time Stamping achieves MIDI playback timing with better than 1 millisecond accuracy. Every MIDI event is “time-stamped,” meaning that every MIDI event is grouped with its time and then sent in packages ahead of time, rather than serially. MIDI Time Stamping provides unprecedented MIDI timing accuracy for better sounding re- sults.
Chapter 5: Basic Use 25 MIDI Thru Mode
The MIDI I/O supports MIDI Thru mode when it is offline—not engaged by a MIDI application on the computer to which it is connected. The Online LED indicator will not be lit when the MIDI I/O is offline.
To use the MIDI I/O in MIDI Thru mode:
1 Supply power to the MIDI I/O (from a com- puter, powered USB hub, or a qualified external power supply.
2 Connect the MIDI Out port of your MIDI con- troller device (such as a MIDI keyboard control- ler) to any MIDI In port on the MIDI I/O.
3 Connect the other MIDI Out ports of the MIDI I/O to the MIDI In ports of the MIDI de- vices you want to control.
The MIDI I/O will operate in MIDI Thru mode.
By default, MIDI Thru mode automatically routes all MIDI In ports to all MIDI Out ports, except the same port to prevent feedback loops. For example, MIDI In port 1 is routed to MIDI Out ports 2–10, MIDI In port 2 is routed to MIDI Out ports 1 and 3–10, and so on.
You can configure your own routing assign- ments using the Matrix Routing settings in the Windows MIDI I/O driver, the Matrix Routing settings in the MIDI I/O setup utility under Mac OS X, and Matrix mode under OMS in Mac OS 9.
For more information, see“Matrix Routing” on page 10, “Matrix Routing” on page 20, or “Matrix Mode” on page 23.

You can also use the Panic/Reset switch on the front panel of MIDI I/O (be sure to press and hold the switch for at least three seconds until the power LED turns off or MIDI I/O will not re- set itself). When re-attaching the USB cable or external power supply, you should see a short LED startup sequence and the Power LED turns on.
If you don’t see this LED startup sequence, the Insufficient USB Power dialog (Macintosh) MIDI I/O is either not receiving sufficient power or there may be a problem with your unit. Please re-check power requirements and if problems persist, contact Digidesign Technical Support.
