Enabling DMA
Enabling your computer's DMA (Direct Memory Access) frees up CPU bandwidth so the com­puter can do other Pro Tools tasks.
In most cases the DMA option will already be set correctly, as Windows XP detects and activates DMA mode by default.
To enable DMA for any IDE hard drives:
1 Choose Start > Control Panel.
2 In Classic View, double-click System.
3 Click the Hardware tab.
4 Under Device Manager, choose Device Man-
ager.
5 In the Device Manager window, double-click
IDE ATA/ATAPI controllers, then double-click the Primary IDE Channel for your IDE hard drive.
6 Click the Advanced Settings tab.
To configure Windows Power Management:
1 Choose Start > Control Panel.
2 Double-click Power Options.
3 Click the Power Schemes tab.
4 From the Power Schemes pop-up menu, select
Always On.
5 Click OK.
This sets System Standby, System Hibernate, and “Turn off hard disks” to Never.
On AMD processors, be sure to check and disable Cool N’Quiet in the System BIOS (in the Cool & Quiet Configuration section). Refer to the manufacturer’s documentation for instructions on disabling this power op­tion, if necessary.
Disabling ClearType Font Smoothing
When using Pro Tools, the Effects “Clear Type” setting must be disabled.
7 For each device, set the Transfer Mode to
“DMA if available,” and click OK.
8 Repeat steps 5–7 for any additional IDE Chan-
nels.

Disabling Hyper-Threading
Pro Tools LE takes advantage of the added pro­cessing power of computers that have multiple processors, or that feature multi-core processing or Hyper-Threading, for RTAS processing.
However, if you set the number of processors available for RTAS processing to 1 (in the Pro Tools Playback Engine dialog), some com­puters with hyperthreading capability may ex­perience decreased performance.
If this occurs, you can increase the number of RTAS processors in the Playback Engine dialog, or you can disable Hyper-Threading on the com­puter.
Refer to your computer’s documentation for steps on how to enter the computer’s BIOS and disable Hyper-Threading.
Disabling System Startup Items
To Disable System Startup Items:
1 From the Start menu, choose Run.
2 Type “msconfig” and click OK. The System
Configuration Utility opens.
3 Under the General tab, choose Selective
Startup.
4 Deselect Load Startup Items and click OK.
5 Click Restart to restart the computer.
6 After restarting, the computer displays a Sys-
tem Configuration message. Check to see if Pro Tools performance has increased before you deselect the “Don't show this message again” option. If performance has not changed, run “msconfig” and return your computer Selective Startup back to Normal Startup. Alternatively, try disabling Startup items and non-essential processes individually.
The fewer items in use by your computer, the more resources are available for Pro Tools. Some startup applications may be consuming unnec­essary CPU resources, and should be turned off.
If you disable any of the following startup items, do so carefully:
• Portable media serial number (required for applications that utilize a copy protection key)
• Plug and play
• Event log
• Cryptographic services
• DHCP Client, TCP/IP Net BIOS, and other networking-related items (unless the com­puter has no network or internet connec­tion, in which case these items can be disabled)

Launching Pro Tools LE

When launching Pro Tools LE the first time, you are prompted to enter an authorization code.
To authorize Pro Tools LE software:
1 Double-click the Pro Tools LE shortcut on
your desktop (or the application icon in the Pro Tools folder inside the Digidesign folder).
2 Enter the authorization code in the dialog
(making sure to type it exactly as printed, and observing any spaces and capitalization), then click Validate.
Your authorization code is located on the inside front cover of this guide.
Pro Tools LE lets you adjust the performance of your system by changing system settings that af­fect its capacity for processing, playback, and re­cording.
In most cases, the default settings for your sys­tem provide optimum performance, but you may want to adjust them to accommodate large or processing-intensive Pro Tools sessions.
Hardware Buffer Size
The Hardware Buffer Size (H/W Buffer Size) con­trols the size of the buffer used to handle host processing tasks such as Real-Time AudioSuite (RTAS) plug-ins. The H/W Buffer setting can also be used to manage monitoring latency.
Lower Hardware Buffer Size settings reduce
monitoring latency, and are useful when you are recording live input.
Higher Hardware Buffer Size settings allow for
more audio processing and effects, and are use­ful when you are mixing and using more RTAS plug-ins.
In addition to causing slower screen re­sponse and monitoring latency, higher Hardware Buffer Size settings can increase the latency caused by RTAS plug-ins, and affect the accuracy of plug-in automation, mute data, and MIDI track timing.

2 From the H/W Buffer Size pop-up menu, select
the audio buffer size, in samples.
3 Click OK.
RTAS Processors
The RTAS Processors setting determines the number of processors in your computer allo­cated for RTAS plug-in processing.
With computers that have multiple processors, or that feature multi-core processing or hyper­threading, this setting lets you enable multi-pro­cessor support for RTAS processes. Used in com­bination with the CPU Usage Limit setting, the RTAS Processors setting lets you control the way RTAS processing and other Pro Tools tasks are carried out by the system.
A higher number of processors reserves more
CPU processing capacity for RTAS plug-in pro­cessing. This is useful for sessions with large number of RTAS plug-ins.
A lower number of processors leaves more
CPU processing capacity for automation, screen redraws, and video playback in Pro Tools, or for other application running at the same time as Pro Tools.
CPU Usage Limit
The CPU Usage Limit controls the percentage of CPU resources allocated to Pro Tools host pro­cessing tasks. Used in combination with the RTAS Processors setting, the CPU Usage Limit setting lets you control the way Pro Tools tasks are carried out by the system.
Lower CPU Usage Limit settings limit the ef-
fect of Pro Tools processing on other CPU-inten­sive tasks, such as screen redraws, and are useful when you are experiencing slow system re­sponse, or when running other applications at the same time as Pro Tools.
Higher CPU Usage Limit settings allocate
more processing power to Pro Tools, and are useful for playing back large sessions or using more real-time plug-ins.
The maximum available CPU Usage Limit de­pends on the number of processors in your com­puter and on the number of processors you specify with the RTAS Processor setting. This value can be up 99 percent for single-processor computers or 90 percent for multi-processor computers.
Increasing the CPU Usage Limit may slow down screen response on slower computers.
Chapter 3: Windows Configuration 15
To change the CPU Usage Limit:
1 Choose Setup > Playback Engine.
2 From the CPU Usage Limit pop-up menu, se-
lect the percentage of CPU processing you want to allocate to Pro Tools.

Pro Tools Hardware Settings

Pro Tools lets you set the default sample rate and clock source for your system, as well as a range of controls specific to each type of audio interface.
3 Click OK.
DAE Playback Buffer Size
The DAE Playback Buffer Size determines the amount of memory DAE allocates for disk buff­ers. The optimum DAE Playback Buffer Size for most disk operations is Level 2.
DAE Playback Buffer Size settings lower than
Level 2 may improve playback and recording initiation speed, but may make it difficult to play or record tracks reliably with sessions con­taining a large number of tracks or a high den­sity of edits, or with systems that have slower or heavily fragmented hard drives.
DAE Playback Buffer Size settings higher than
Level 2 will allow for a higher density of edits in a session or a higher track count when using slower hard drives. However, a higher setting can also cause a time lag to occur when starting playback or recording, or longer audible time lag while editing during playback.
Using a larger DAE Playback Buffer Size leaves less system memory for other tasks. The default setting of Level 2 is recom­mended unless you are encountering -9073 (“Disk too slow or fragmented”) errors.
Default Sample Rate
The Sample Rate setting appears as the default sample rate when you create a new session. (This setting is available in the Hardware Setup dialog only when no session is open.)
You can change the sample rate when creat­ing a new Pro Tools session by selecting a different sample rate in the New Session dialog. (Refer to
Guide for details.)
To change the default Sample Rate:
1 Choose Setup > Hardware.
Hardware Setup dialog for Mbox 2 Pro
2 Select the sample rate from the Sample Rate
pop-up menu.
3 Click OK.
