Plug-In Streaming Buffer Size
(Structure Plug-In Only)
This setting appears in the Playback Engine only if
the Structure sampler instrument plug-in is in-
stalled on your system (this applies to Structure LE
and Structure Free as well). The
Plug-In Streaming
Buffer Size
determines the amount of memory
DAE allocates for streaming playback from disk
with the Structure plug-in. This setting only affects
playback if disk streaming is activated in Struc-
ture’s plug-in controls (see the AIR Virtual In-
struments Guide for more information).
The optimum
Plug-In Streaming Buffer Size for
most sessions is
250 ms; Level 2 (Default).
•
Plug-In Streaming Buffer Size settings lower
than
250 ms; Level 2 (Default) reduce the
amount of system memory used for sample play-
back and free up memory for other system tasks.
However, reliability of sample playback may de-
crease.
•
Plug-In Streaming Buffer Size settings higher
than
250 ms; Level 2 (Default) improve the reli-
ability of sample playback, but they also de-
crease the amount of memory available for other
system tasks, such as Native plug-in processing.
To change the Plug-In Streaming Buffer Size:
1 Choose Setup > Playback Engine.
2 From the Plug-In Streaming Buffer Size pop-up
menu, select a buffer size.
3 Click OK.
Optimizing the Plug-In
Streaming Buffer Size
(Structure Plug-In Only)
This option appears in the Playback Engine only if
the Structure plug-in is installed on your system.
This option is useful when you are playing samples
from the same drive that contains audio for the cur-
rent session. When this option is selected,
Pro Tools automatically optimizes the size of the
Plug-In Streaming Buffer to facilitate disk access
from both Pro Tools and Structure. The
Plug-In
Streaming Buffer Size
pop-up menu is unavailable
when this option is selected.
To set Pro Tools to automatically optimize the
Plug-In Streaming Buffer Size:
1 Choose Setup > Playback Engine.
2 Select the Optimize for Streaming Content on
Audio Drives
option.
3 Click OK.
Configuring MIDI Setup
If you plan to use any external MIDI devices with
Pro Tools (such as controllers, keyboards, synthe-
sizers, drum machines, samplers, sequencers, or
sound modules), you may want to configure your
MIDI setup using Audio MIDI Setup (Mac) or
MIDI Studio Setup (Windows).
Using a larger Plug-In Streaming Buffer Size
leaves less system memory for other tasks.
The default setting of 250 ms (Level 2) is rec-
ommended unless you are experiencing prob-
lems with the reliability of streaming play-
back from disk.
