Pro Tools LE Capabilities
Pro Tools LE software provides the following ca-
pabilities with Mbox:
•Playback up to 32 mono digital audio
tracks, and playback up to 30 tracks while
recording up to 2 tracks, depending on
your computer’s capabilities.
• Sessions can include up to 128 audio tracks
(with 32 voiceable tracks maximum), 256
MIDI tracks, 128 Auxiliary Input tracks,
and 64 Master Fader tracks.
•16-bit or 24-bit audio resolution, at sample
rates up to 48 kHz.
• Nonlinear, random-access editing and mix
automation.
• Audio processing with up to 5 RTAS plug-
ins per track, depending on your com-
puter’s capabilities.
• Up to 5 inserts and 5 sends per track
• Up to 16 internal mix busses.
Mbox will not function properly if connected
to a USB hub. If you need to use a hub for
other USB peripherals, use a separate USB
port; Mbox must have a dedicated port in or-
der to function properly.
Pro Tools LE uses your computer’s CPU to
mix and process audio tracks (host process-
ing). Computers with faster clock speeds
yield higher track counts and more plug-in
processing.
