The following iMac G4 Flat Panel computers are qualified for use with Digi 002 Rack Pro Tools LE systems, but may result in lower performance:

  • iMac G4 – 800 MHz 15 and 17 Inch Display
  • iMac G4 – 700 MHz 15 Inch Display

Not Tested:

  • Apple eMac — All Models
  • Although not tested by Digidesign, there are no known issues with the eMac compared to iMac G4 models with similar processor speeds.

Additional Requirements

System Software

Pro Tools 6.9.2 or higher is required for the Mac OS X version 10.4 "Tiger" operating system. Earlier versions of Pro Tools will not work on Mac OS 10.4.

iLok Authorized Plug-Ins

Although not required with Pro Tools installation, an iLok USB Hardware Key may be required for installation of some plug-ins and optional software applications.

Control Surfaces & MIDI Interfaces

Hard Drives — Audio Storage Requirements

Although limited recording and playback of audio tracks may be possible using the internal startup drive, a separate dedicated audio hard drive is highly recommended for maximum performance and track count.

Audio Storage Requirements for Record and Playback:

Firewire Hard Drives

Maximum Performance Guidelines

  • Recording to the system startup drive is not recommended or supported
  • When using FireWire storage with Digi 002 systems, connect the Digi 002 and the drives to separate FireWire ports if possible
  • If only one port is available, connect the drives to the CPU using a 1 meter firewire cable, then connect the Digi 002 to the drives

Pro Tools Does Not Support Sleep Mode

In the Macintosh System Preferences, launch Energy Saver, click the Sleep tab, and disable all Sleep features. Set "Put the computer to sleep when it is inactive" to Never. Do not manually put your computer to sleep when running Pro Tools.

Known Incompatibilities & Issues

  • The Movie Offset feature affects both the QT Movie output to DV and the Onscreen movie
  • If users want to use Japanese fonts in their sessions, they will not be able to use HFS (standard) drives – only HFS+ formatted drives
  • Sometimes when opening a session that was based on a PT 3.2 format session, the following error may occur when Restoring IO paths: Time type mismatch occurred in "Time_Typed.cpp" line 370. A reboot may be necessary if this occurs
  • System instabilities and performance issues can occur when using MIDI control surfaces in conjunction with Pro Tools 6 and 3rd party MIDI interfaces. For best multiport MIDI performance, we recommend using Digidesign's MIDI I/O. (only if additional MIDI ports are required beyond the 16 in/32 out built into the Digi 002)
  • Pro Tools LE core systems cannot be combined, and multiple units are not supported. For instance:
    • A Digi 002 and Digi 002 Rack cannot be used together on the same computer at the same time.
    • 2 Digi 002 Rack units cannot be used on the same computer.
    • Digi 002 faders cannot be used with any other system, including Digi 002 Rack
  • Pro Tools 6 does not work in the OS 9 "Classic Mode". You must choose Mac OS X as your Startup Disk.
