When Low Latency Monitoring is enabled,
Pro Tools disables software monitoring for re-
cord-enabled tracks routed to Outputs 1–2 only.
This lets you use the built-in mixer function on
your Core Audio or ASIO hardware for record
monitoring with Outputs 1 and 2 on your Core
Audio or ASIO audio interface. Also, any plug-
ins and sends assigned to record-enabled tracks
are automatically bypassed, and must remain
bypassed. Additionally, these tracks do not reg-
ister on meters for Master Fader tracks in
Pro Tools.
New Session File Format
Pro Tools 10 uses a new session file format
(.ptx). This means that sessions created in
Pro Tools 10 cannot be opened in lower versions
of Pro Tools. To share sessions with lower ver-
sions of Pro Tools, you will need to use
Save
Session Copy As
to save a copy of the session to
a lower session file format (see “New Save Ses-
sion Copy Options” on page 14).
New Clip Group File Format
Pro Tools 10 uses a new clip group file format
(.cgrp). Region group files (.rgp) created with
lower versions of Pro Tools can be imported into
Pro Tools 10 sessions, but clip group files
(.cgrp) cannot be imported into lower versions
of Pro Tools. This new format maintains clip
gain settings with clip groups.
Support for 32-bit Floating
Point Audio Files
Pro Tools 10 supports 32-bit floating point au-
dio files. Sessions can be set to 32-bit floating
point when they are created, or while they are
open using the Session Setup window.
Using a 32-bit floating point bit depth for audio
files in Pro Tools sessions can help avoid clip-
ping with AudioSuite rendering, or unnecessary
dithering with AudioSuite rendering. It can also
help avoid rounding errors in signal processing
(which can occur during bit-depth conversion
for file playback and real-time plug-in insert
processing). However, 32-bit files take up a
third more disk space and audio streaming
bandwidth, which can be problematic with
higher track counts when using slower hard
drives.
To create a Pro Tools session using 32-bit floating
point audio files:
1 Choose File > New Session.
2 In the New Session dialog, enable the 32 Bit
Float
option. Set the other options as desired.
3 Click OK.
For information about configuring your
audio interface’s hardware mixer for di-
rect monitoring, please refer to the manu-
facturer’s documentation.
Press Command+B (Mac) or Control+B
(Windows) to toggle the Bit Depth setting.
