Mbox 2 Pro Getting Started22

You can set Pro Tools to reserve only the mini-

mum amount of required memory, so that more

system memory is available to other applica-

tions.

To minimize system memory allocation:

1 Choose Setup > Playback Engine.

2 Select the “Minimize System Memory Allocation”

option.

3 Click OK.

4 Restart your computer.

Plug-in Streaming Buffer Size

(Structure Plug-in Only)

This setting appears in the Playback Engine dia-

log only if the Structure sampler instrument

plug-in is installed on your system. The Plug-in

Streaming Buffer Size determines the amount of

memory DAE allocates for streaming playback

from disk with the Structure plug-in. This set-

ting only affects playback if disk streaming is ac-

tivated in Structure’s plug-in controls (see the

Structure Plug-in Guide for more information).

The optimum Plug-in Streaming Buffer Size for

most sessions is 250 ms (Level 2).

• Plug-in Streaming Buffer Size settings lower

than 250 msec (Level 2) reduce the amount of

system memory used for sample playback and

frees up memory for other system tasks. How-

ever, audio quality of sample playback may de-

crease.

• Plug-in Streaming Buffer Size settings higher

than 250 msec (Level 2) improve the audio qual-

ity of sample playback, but they also decrease

the amount of memory available for other sys-

tem 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 optimize the Plug-in Streaming

Buffer Size:

1 Choose Setup > Playback Engine.

2 Select the “Optimize for Streaming Content” op-

tion.

3 Click OK.

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 audio quality of sample

playback.
