• Plug-in Streaming Buffer Size settings higher
than 250 msec (Level 2) improve the reliability
of sample playback, but they also decrease the
amount of memory available for other system
tasks, such as RTAS 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 dia-
log only if the Structure sampler instrument
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 current
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 unavail-
able 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 Au-
dio Drives option.
3 Click OK.
Configuring MIDI Setup
If you plan to use any MIDI devices with Pro Tools,
do one of the following:
 On Windows, configure your MIDI setup with
MIDI Studio Setup. See Appendix C, “Configur-
ing MIDI Studio Setup (Windows Only)” for de-
tails.
– or –
 On Mac, configure your MIDI setup with Au-
dio MIDI Setup. See Appendix D, “Configuring
AMS (Mac OS X Only)” for details.
Using a larger Plug-in Streaming Buffer Size
leaves less system memory for other tasks.
The default setting of 250 ms (Level 2) is
recommended unless you are experiencing
problems with the reliability of streaming
playback from disk.
