Chapter 1: Welcome to Pro Tools|HD Native 3
An iLok can hold hundreds authorizations for 
all of your iLok-enabled software. Once an iLok 
is authorized for a given piece of software, you 
can use the iLok to authorize that software on 
any computer.
MIDI Requirements
USB MIDI interfaces (such as the M-Audio 
MIDI-SPORT series) and USB MIDI controllers 
(such as the M-Audio Axiom Pro series) work ef-
fectively with Pro Tools systems on Windows or 
Mac. 
For a list of supported MIDI interfaces and con-
trollers, refer to our website (www.avid.com).
Hard Drive Requirements
For optimal audio recording and playback, 
Pro Tools|HD Native systems require one or 
more qualified hard drives.
Initialize your hard drives with the Disk Utility 
application included with Apple System soft-
ware (Mac) or using Windows Disk Manage-
ment (Windows).
Avoid Recording to the System Drive
Recording to your system drive is not recom-
mended. Recording and playback on a system 
drive may result in lower track counts and fewer 
plug-ins.
Registration
Review the enclosed Registration Information 
Card and follow the instructions on it to quickly 
register your purchase online. This is one of the 
most important steps you can take as a new user. 
Registering your purchase is the only way you 
can be eligible to receive:
• Information regarding technical support
• Future upgrade offers
• Limited warranty on hardware
An authorized iLok must be inserted in an 
available USB port on your computer to run 
Pro Tools HD.
For information about installing and au-
thorizing your Pro Tools HD software, see 
the printed 
Pro Tools Installation Guide in-
cluded with your Pro Tools Software Pack-
age.
If you have multiple hard drives in your sys-
tem, use DigiBase to designate the system 
drive as a Playback or Transfer only drive 
for optimal performance. For more informa-
tion about using DigiBase, see the Pro Tools 
Reference Guide.
