What’s New in Pro Tools and Pro Tools HD 10.052
Cache Meters in the System
Usage Window
Pro Tools HD 10 provides two new meters in the
System Usage window for monitoring the Disk
Cache:
Disk Cache and Timeline Cached. These
meters are only present if a fixed
Cache Size is
selected in the Playback Engine dialog.
Disk Cache Displays the percentage of how
much of the allocated disk cache is filled. For ex-
ample, if the
Cache Size in the Playback Engine
is set to 1 GB and a session uses 250 MB of audio
files, the
Disk Cache meter reads 25%. If all of
the audio in the session is cached (including
files in the Clip List that are not on the time-
line), the Disk Cache meter appears green.
Timeline Cached Displays the amount of audio
in the session Timeline cached in RAM.
If the selected
Cache Size in the Playback En-
gine is the same or greater than the amount of
audio on the Timeline, the
Timeline Cache meter
reads 100% and it appears green (indicating that
all of the audio on the Timeline is cached in
RAM). This is useful for letting you know how
much audio can still be added to the Timeline
and be cached in RAM.
If the total amount of audio in the Timeline is
more than the selected
Cache Size in the Play-
back Engine, the
Timeline Cached meter shows
the percentage of audio on the Timeline that is
cached in RAM. For example, if the selected
Cache Size in the Playback Engine is 256 MB
and the amount of audio on the Timeline is 1
GB, the
Timeline Cached meter reads 25%.
Enhanced Support for
Network Attached Storage
Network Attached Storage
Pro Tools 10 supports all Mac OS X and Win-
dows 7 supported network attached storage for
opening, playing back, and recording Pro Tools
sessions.
With network attached storage, performance is
not guaranteed and is dependent on a variety of
factors, including:
• Type of storage (such as SATA or SAS)
• Number of disks in a RAID volume
• Network topology (such as Gigabit Ether-
net, 10 Gigabit Ethernet, or Fibre Channel)
• Number of simultaneous users
System Usage window showing Disk Cache and
Timeline Cached meters
With Pro Tools HD and Pro Tools with Com-
plete Production Toolkit, you can assign
more RAM than the size of the session being
opened in the RAM cache for optimal perfor-
mance (Setup > Playback Engine).
