MIDI Requirements

Both USB and serial MIDI interfaces work effec­tively with Pro Tools.
PCI-based serial expanders do not work with se­rial MIDI interfaces on Macintosh systems. Se­rial MIDI interfaces require a qualified modem­to-serial port adapter. Refer to the Digidesign Web site (www.digidesign.com) for a list of sup­ported adapters.

Hard Drive Requirements

For optimal audio recording and playback, all Pro Tools TDM systems require one or more Digidesign-qualified drives.
Drive Formats
Windows
formatted with FAT32 or NTFS file system (NTFS preferred).
Macintosh
formatted with HFS or HFS+ file system only.
Windows XP systems should use drives
Macintosh systems should use drives

System Requirements

Compatibility Information
Digidesign can only assure compatibility and provide support for hardware and software it has tested and approved. For a list of Digidesign­qualified computers, operating systems, hard drives, and third-party devices, refer to the latest compatibility information on the Digidesign Web site (www.digidesign.com/compato).

The UNIX File System (UFS) is not sup­ported with Pro Tools on Mac OS X.
Hard drive performance depends on factors in­cluding system configuration, number of tracks, session sample rate, density of edits, and the use of crossfades and other processes such as Beat Detective in a session.
Be sure to check the latest compatibility infor­mation on the Digidesign Web site for SCSI and FireWire requirements for maximum track counts on Windows and Macintosh (www.digidesign.com/compato).
SCSI Hard Drives
IDE/ATA Hard Drives
For maximum recording and playback perfor­mance, Digidesign recommends qualified SCSI hard drives and a qualified SCSI host bus adapter (HBA) card or (on Windows systems) a qualified built-in SCSI HBA connector on the motherboard.
Qualified SCSI drives yield up to 32 tracks per drive with 24-bit audio
Windows
can be used simultaneously.
Macintosh On Mac OS X, up to four SCSI drives can be used simultaneously.
On Windows XP, up to six SCSI drives
FireWire Hard Drives
Digidesign recommends qualified FireWire drives and (on Windows only) a qualified FireWire host adapter.
Qualified FireWire drives yield up to 24 tracks per drive with 24-bit audio.
Windows On Windows XP systems without an expansion chassis, up to six FireWire drives can be used simultaneously. On Windows XP sys­tems with Pro Tools cards installed in an expan­sion chassis, up to four FireWire drives can be used simultaneously.
A qualified internal IDE/ATA drive yields up to 32 tracks of 24-bit audio, at 44.1 kHz or 48 kHz when used as a dedicated audio drive.
For maximum performance, Digidesign rec­ommends the use of SCSI hard drives. IDE hard drives provide limited track count per­formance and are not supported when an Expansion Chassis is used. For more infor­mation regarding Expansion Chassis oper­ating procedures, see the Pro Tools Ex­panded Systems Guide.
Visit the Digidesign Web site (www.digidesign.com) for a list of qualified hard drives and SCSI HBA cards.
Avoid Recording to System Drives
Although Pro Tools will let you record to your system drive, this is generally not recom­mended. Recording and playback on system hard drives results in lower track counts and fewer plug-ins.
Digidesign does not recommend recording to system drives. Record to system drives only when necessary.
Macintosh On Mac OS X, up to eight FireWire drives can be used simultaneously.

Hard Drive Storage Space
Mono audio tracks recorded with 16-bit resolution at 44.1 kHz (CD quality) require approximately 5 MB of hard disk space per minute.
The same tracks recorded with 24-bit resolution require about 7.5 MB per minute. Table 2 on page 6 lists the required drive space for certain track numbers and track lengths, to help you estimate your hard disk usage.

Windows Configuration
Installation of a Pro Tools|HD-series system on a Windows computer includes the following steps:
1 Installing Windows XP (See “Installing Win-
dows XP” on page 9.)
2 Configuring your computer and its hardware
components in preparation for Pro Tools instal­lation (See “Configuring Your Computer” on page 10.)
3 Configuring Windows system software set-
tings for compatibility and optimal perfor­mance (See “Windows System Settings” on page 13.)
4 Installing Pro Tools hardware (See “Installing
Pro Tools Hardware” on page 16.)
5 Installing Pro Tools TDM software (See “In-
stalling Pro Tools Software” on page 23.)
6 Checking your Pro Tools system (See “Check-
ing Your HD System” on page 26.)

Installing Windows XP

If you do not already have Windows XP in­stalled on your computer, you will need to in­stall Windows XP Professional edition or Windows XP Home edition. Pro Tools requires an activated version of Windows XP with ad­ministrator privileges.
For best performance, Digidesign strongly rec­ommends a clean installation of Windows on a newly formatted drive or partition rather than upgrading the operating system.
If you are changing or upgrading your oper­ating system, be sure to deauthorize any key disk authorized plug-ins before changing or upgrading to avoid losing any authoriza­tions. See the iLok Usage Guide for informa­tion on the iLok Smart Key for software au­thorizations.
7 Configuring your Pro Tools system (See “Con-
figuring Pro Tools” on page 29.)
Chapter 2: Windows Configuration 9
Configuring Your Computer
To ensure optimum performance with Pro Tools, configure your computer before in­stalling Pro Tools hardware and software.
Before you make any changes to your com­puter’s system settings, make a backup copy of your registry (where many of these essen­tial settings are stored). By doing so, you will be able to restore your system’s original settings in case of trouble. Consider acquir­ing a disk recovery utility such as Norton Ghost for additional security. See your Win­dows XP documentation for details.
If your computer does not provide the BIOS configuration options included in this sec­tion, or if you do not feel comfortable changing system parameters, consult with a Windows system administrator, computer dealer, or manufacturer for assistance.
Configuring the BIOS
2 While the computer is starting up, enter BIOS
Setup by pressing the appropriate key (usually indicated in the startup message) on your com­puter keyboard. The F1, F2, or the Delete keys are commonly used.
3 In the appropriate page of the BIOS Setup, dis-
able PCI Parity. If the PCI Parity option isn’t available on your computer, skip this step.
4 If you will be using SCSI drives or devices, and
your computer is equipped with built-in SCSI hardware, enable SCSI support. SCSI support pa­rameters are typically found on the Devices & I/O Options page of the BIOS setup utility. If you do not have built-in SCSI hardware and are us­ing a SCSI host bus adapter (HBA) card instead, you do not need to enable SCSI support.
5 Disable Power Management, if present.
6 Enable PCI Dynamic Bursting, if present.
7 Save the new BIOS settings.
8 Exit BIOS setup and restart your computer.
BIOS (Basic Input/Output System) parameters vary depending on the make and model of the computer. Refer to the documentation that came with your computer for more details.
Different BIOS manufacturers often use differ­ent names to describe the same system function. Some manufacturers do not provide a particular configuration option at all. The names and op­tions that appear in your computer’s BIOS may differ from those described in this section.
The following BIOS settings are not applica­ble to the Compaq Evo W8000 and the IBM Intellistation M Pro 6850.
To modify your computer’s BIOS:
1 Start or restart your computer.
Getting Started with HD10
Configuring the SCSI BIOS
If you are using SCSI drives or devices, you must modify the settings of your built-in SCSI hard­ware or SCSI host bus adapter card. This allows SCSI hard drives to work properly with Pro Tools. This procedure varies on different computers. Refer to the documentation that came with your computer.
To modify your computer’s SCSI BIOS:
1 Start or restart your computer.
2 While the computer is starting up, when the
text message regarding the SCSI BIOS appears, press the key combination listed on the screen to enter the SCSI BIOS setup utility.
3 Refer to your SCSI host bus adapter card doc-
umentation to set the following parameters:
• For each SCSI ID and SCSI channel con­nected to your audio drives, set the Maxi­mum Sync Transfer Rate parameter to 20 MB/sec for the ATTO EPCI-DC, or to Ul­tra 160 for Ultra 160 cards.
• If you are using an ATTO host bus adapter card, change the PCI Burst Size to 128 Bytes and the Burst Length Selection Timeout to 16 ms (UL3D only).
• If you are using an Adaptec host bus adapter card, enable the Host Adapter BIOS option.
4 Save the new SCSI BIOS settings.
5 Exit SCSI BIOS setup and restart your com-
puter.
8 Select Adapter Menu.
9 Select Update Flash ROM.
10 Press Enter twice.

Updating the SCSI BIOS
If you are using an ATTO SCSI HBA card, you may need to update its SCSI BIOS. When start­ing your computer, you will see what version of the ATTO SCSI BIOS is installed on the SCSI card. If it is not version 1.6.8 or higher, you will need to flash the SCSI BIOS with 1.6.8 or higher ATTO SCSI BIOS (flash.bat).
To update the BIOS on the ATTO SCSI card:
1 Insert a High Density PC formatted floppy
disk in your floppy drive.
2 Copy the DOS folder from the ATTO folder on
the Pro Tools Installer CD-ROM to the floppy disk.
3 Shut down your computer.
4 Disconnect any hard drives connected to the
SCSI card.
5 Start your computer with the floppy disk in
the floppy drive.
6 When prompted, press Control+Z.

Installing SCSI Drivers

For Pro Tools to run at maximum efficiency with SCSI Host Bus Adapters and SCSI drives, in­stall a Digidesign approved SCSI driver (ATTO or Adaptec, depending on the card you are using).
Check Digidesign’s Compatibility Docu­ments for a list of Digidesign approved com­puters and supported SCSI driver versions. Compatibility Documents and other re­sources are available at the Digidesign Web site (www.digidesign.com).
Installing the Adaptec SCSI Driver
If you need to install the Adaptec driver, refer to the driver manufacturer’s documentation.
The full name of the Adaptec driver for the IBM M Pro or Compaq Evo W8000 is:
Adaptec
AHA290/291/294x/394x/4944/ AIC78xx

Should this problem occur, remove all plug and play cards and you will be able to boot Win­dows, then shut down and re-install the cards according to the installation instruc­tions in “Installing Pro Tool|HD Cards” on page 17. You should now be able to boot Windows.
Chapter 2: Windows Configuration 17

Connecting Pro Tools|HD Cards

In HD systems that include more than one card, you must connect all the HD cards to each other with TDM FlexCables.
Each HD card has two ports along the top of the card, labeled Port A and Port B. The FlexCable has two connectors, also labeled Port A and Port B, to ensure proper connection. Data communi­cation across multiple HD cards is achieved by connecting Port B of the first card to Port A of the next card with a TDM FlexCable.
To connect HD cards with the TDM FlexCable:
1 Shape the FlexCable before installing it on
your HD cards by grasping the cable with both hands and moving the Port B portion of the ca­ble straight towards you and inwards, as shown below. Do not bend the cable more than you need to, as you may damage the traces in the ca­ble.
2 Slide the FlexCable into the notch of the first
card, so that the Port B connector of the FlexCa­ble can be aligned with Port B of the first card; and the Port A connector of the FlexCable can be aligned with Port A of the second card, as shown below.
HD Accel Card (or HD Process card)
Inserting TDM FlexCable
3 Connect the Port A connector of the FlexCa-
ble to Port A on the second card. Push down gently but firmly until the cable is fully con­nected to the card. Attach the other end of the FlexCable (labeled Port B) to Port B on the first card.

5 For systems with more than two cards, con-
nect each additional card to its preceding card. Use FlexCables to connect card pairs together, as described above, until all cards are connected. (Each HD Accel card is packaged with a FlexCa­ble.)
6 Close the computer case.
7 Proceed to “Connecting Audio Interfaces” on
page 19.

Connecting Audio Interfaces

Each Pro Tools|HD-series audio interface sup­plies up to 16 channels of input and output to your system. Audio interfaces are connected di­rectly to Pro Tools|HD cards, or through the Ex­pansion ports on other HD-series interfaces.
Each HD card supports up to 32 channels. To get a full 32 channels of I/O from one card, you can connect, or daisy-chain, a second 16-channel HD I/O to the first HD I/O that is connected directly to the HD card.
Pro Tools|HD supports up to a maximum of eight 192 I/Os, 192 Digital I/Os, or 96 I/Os. Up to four 96i I/Os can be used simultaneously.
For examples of connecting multiple HD I/Os, see Figure 1 and Figure 2 on page 21.
HD audio interfaces need room at their sides to maintain proper air flow for cool­ing. It is important to leave room for air in­take and ventilation on the sides of the unit. Do not block the sides of the unit or discon­nect the internal fan. If the units are rack­mounted in a case, remove the case lids or doors before operating the system. Failure to do so can result in the units overheating very quickly, which can permanently dam­age sensitive components.
Earlier audio interfaces can also be connected to the 192 I/O, 192 Digital I/O, or 96 I/O (the 96i I/O does not support Legacy interfaces). These include: 888|24 I/O, 882|20 I/O, 1622 I/O, 24-bit ADAT Bridge I/O, and the orig­inal ADAT Bridge I/O. The original 888 I/O and 882 I/O interfaces are not supported with Pro Tools|HD.
To connect HD audio interfaces:
1 If you are using a single 192 I/O,
192 Digital I/O, 96 I/O, or 96i I/O, connect its Primary Port to the HD Core card with the Dig­iLink cable provided with the HD Core card. You must attach at least one 192 I/O, 192 Digital I/O, 96 I/O, or 96i I/O to your sys­tem in order for Pro Tools to launch.
If you have at least one 192 I/O or 192 Digital I/O in your system configura­tion, it must be connected to the HD Core card as the primary interface.
2 Connect additional HD audio interfaces to
subsequent Digidesign audio cards, or daisy­chain your I/Os (by connecting the Primary Port of the secondary I/O to the Expansion Port of the primary I/O).
If you are connecting both 192 I/O (or 192 Digital I/O) and 96 I/O audio interfaces to your system, connect the 192 I/O (or 192 Digital I/O) to your HD Core card, followed by any additional 192 I/O (or 192 Digital I/O) interfaces connected to the next highest-prior­ity cards. Then connect 96 I/O interfaces to sub­sequent cards, or to other interfaces, then con­nect 96i I/O interfaces.
You can also connect a single HD I/O to each HD card in your system using the provided DigiLink cables. There is no advantage to this configura­tion over daisy-chaining I/Os.
Chapter 2: Windows Configuration 19
3 If you are using two or more HD audio inter-
faces, connect the Loop Sync Out of each inter­face to the Loop Sync In of the next interface with the BNC cables included in your HD I/O packaging. Then, connect the Loop Sync Out of the last interface to the Loop Sync In of the pri­mary interface.
12-ft DigiLink cable
4 If you are connecting a Digidesign Legacy au-
dio interface (such as an 888|24 I/O, 882|20 I/O, 1622 I/O, or Digidesign ADAT Bridge I/O), con­tinue with “Connecting an Additional 16 Chan­nels of Audio with Legacy Audio Interfaces” on page 21. (The 96i I/O does not support Legacy interfaces.)

Connecting an Additional 16 Channels of Audio with Legacy Audio Interfaces
Each 192 I/O, 192 Digital I/O, and 96 I/O can support 16 channels of audio to and from Digidesign Legacy I/Os. (The 96i I/O does not support Legacy I/O.) Legacy I/Os include the 888|24 I/O, 882|20 I/O, 1622 I/O, 24-bit ADAT Bridge I/O, and the original ADAT Bridge I/O. The original 888 I/O and 882 I/O interfaces are not supported with Pro Tools|HD.
TDM FlexCable
HD Accel or HD Process
To connect Digidesign Legacy audio interfaces:
1 Connect the “MIX card” end of the peripheral
cable that came with your Legacy audio inter­face (60-pin side) to the Legacy Port on the pri­mary HD audio interface. Connect the other end to the Computer Port on the Legacy audio interface.

face, supply its 256x clock from the HD I/O to which its 60-pin cable is attached (either your second audio interface, or directly to an HD Accel or HD Process card).
If you are using a Y cable (Legacy 16-channel pe­ripheral cable adapter), connect this to the Leg­acy port first, then connect the audio interface peripheral cables to Port A and Port B of the Y cable.
“A” to first Legacy I/O
Optional 16-channel peripheral cable adapter
3 To properly clock the Legacy audio interface,
“B” to second Legacy I/O
to Legacy Port on HD audio interface
connect the Ext. Clock output port on the HD I/O to the Slave Clock IN on the Legacy audio interface. The Legacy audio interface will switch to Slave mode once the proper clock is output­ting from the HD I/O. Always use the Ext. Clock Out port of the same I/O to which the Legacy audio interface is attached.
To ensure the proper functioning of Legacy audio interfaces (such as an 888|24 I/O or 882|20 I/O), launch Pro Tools and declare the Legacy audio interfaces in the Hardware Setup dialog before turning them on. Then quit Pro Tools, shut down your computer, turn on your audio interfaces, and turn on your computer.
Before you turn on and configure your Leg­acy audio interfaces, turn down the volume of output devices. Very loud digital noise may be emitted before the Legacy audio in­terface is initialized.
If you are using the Y cable to connect multiple MIX-series audio interfaces, you must also con­nect the Slave Clock Out of the first Legacy in­terface to the Slave Clock In of the second Leg­acy interface with the provided BNC cable. You cannot clock more than two MIX-series audio interfaces from a single HD-series audio inter­face. If you have a third MIX-series audio inter-

Configuring Pro Tools

Pro Tools System Settings

Pro Tools 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.
Voice Count
The Number of Voices setting lets you control the number of voices available on your system. For example, the default number of voices on an HD Core system is 48 voices, using one DSP (at sample rates of 44.1 kHz or 48 kHz).
Changing the number of voices affects DSP usage, the total number of voiceable tracks, and overall system performance.
Depending on the current sample rate and the number of HD Core, HD Accel, and HD Process cards in your system, you will have different choices for voice count.
For additional information, see the Pro Tools Reference Guide.
To change the Voice Count:
1 Choose Setups > Playback Engine.
Playback Engine dialog for Pro Tools|HD Accel system
2 Select the number of voices and DSPs to allo-
cate for voicing by choosing a value from the Number of Voices pop-up menu.
• Select higher voice numbers when your Digidesign cards are the only PCI cards in your computer, or when you are using an expansion chassis to run higher track counts (such as 64 tracks at 96 kHz) and you want more voices per DSP (such as 16 voices per DSP at 96 kHz). These settings use fewer DSP chips for mixing (leaving more available for plug-ins) but place the highest processing load on each.
• Select medium voice numbers when your Digidesign cards are in an expansion chas­sis, or when you are using other PCI cards along with Digidesign cards. These settings generally provide an optimum balance be­tween number of chips needed for voicing, and the processing load placed on each.
Chapter 2: Windows Configuration 29
• Select minimum voice numbers if you are using high-bandwidth PCI cards (such as video capture cards) along with your Digidesign cards. These settings place the lightest processing load on each allocated DSP chip, but generally require more DSP chips be dedicated to voicing and mixing (leaving fewer available for plug-ins).
Number of Voices menu (HD Accel-equipped system)
3 Click OK.
Hardware Buffer Size
The Hardware Buffer Size (H/W Buffer Size) con­trols the size of the hardware cache used to han­dle host processing tasks such as Real-Time Au­dioSuite (RTAS) plug-ins.
• 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 affect the accuracy of plug-in automation, mute data, and timing for MIDI tracks.
To change the Hardware Buffer Size:
1 Choose Setups > Playback Engine.
2 From the H/W Buffer Size pop-up menu, select
the audio buffer size, in samples.
3 Click OK.
CPU Usage Limit
The CPU Usage Limit controls the percentage of CPU resources allocated to Pro Tools host pro­cessing tasks.
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.
Increasing the CPU Usage Limit may slow down screen responses on slower computers.
To change the CPU Usage Limit:
1 Choose Setups > 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.
3 Click OK.

DAE Playback Buffer Size

Pro Tools Hardware Settings

The DAE Playback Buffer Size determines the amount of memory DAE uses to manage disk buffers, which affects system performance.
Lower DAE Playback Buffer Size settings can
improve playback and recording initiation speed. However, a lower setting can make it dif­ficult for slower hard drives to play or record tracks reliably.
Higher DAE Playback Buffer Size settings can
allow for a higher density of edits in a session. However, a higher setting can cause a time lag to occur before playback or recording begins. It can also cause a time lag to occur when you are ed­iting during playback.
To change the DAE Playback Buffer Size:
1 Choose Setups > Playback Engine.
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.)
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. (See
To change the default Sample Rate:
1 Make sure that no Pro Tools session is open.
2 Choose Setups > Hardware Setup.

Configuring I/O Setup
The I/O Setup dialog provides a graphical repre­sentation of the signal routing for each con­nected audio interface, with controls to route physical ports to Pro Tools inputs and outputs. These controls mirror the routing controls found in the Hardware Setup dialog—changes made to physical routing in one dialog are al­ways reflected in the other. The I/O Setup dialog also lets you label and map Pro Tools input, out­put, insert, and bus signal paths.
To configure I/O routing in I/O Setup:
1 Choose Setups > I/O Setup.
2 Click the Input or Output tab to display the
corresponding connections.
3 To change the name of a path or subpath,
double-click directly on the Path Name, type a new name for the path, and press Enter.
4 To change the destination of an Input or Out-
put path or subpath, click directly on an Input or Output Selector for an interface channel pair, just below an audio interface icon. (This feature is not available for the 96i I/O.)
5 From the pop-up menu, select a physical port
pair (such as Analog 1–2), to route to the corre­sponding Pro Tools channel pair (such as A 1–2) in the Path Name column on the left.
6 Repeat the above steps for additional channel
pairs.
7 Click OK.
Pro Tools comes with default I/O Setup settings that will get you started. You only need to go to I/O Setup if you want to remap or rename the default I/O paths or if you change your system hardware (for example, adding an expansion card to a 192 I/O).
I/O Setup dialog
Chapter 2: Windows Configuration 37
Routing a Pro Tools Output Pair to Multiple Destinations
Pro Tools channel pairs can be routed to multi­ple outputs on your Digidesign audio interface through the Hardware Setup dialog.
For example, if you assign both Analog 1–2 and Analog 3–4 interface outputs to Pro Tools Out­put pair 1–2, when you send a signal to Pro Tools Outputs 1–2, that signal will be routed simultaneously to both pairs of output ports on your audio interface.
This lets you send the same signal (such as a ste­reo pair, a stem mix, or a multichannel mix) to multiple destinations (such as multiple master­ing devices).
To route a Pro Tools output channel pair to multiple audio interface output ports:
1 Choose Setups > Hardware Setup.
2 From the Peripherals list, select an interface.
3 Click the Main tab.
4 Select an output pair from an Output pop-up
menu.
5 Start-click the same pop-up menu and choose
an additional output pair.
The output name updates with a plus sign (“+”) before it to indicate that multiple output ports are selected. In the pop-up menu, each physical port pair assigned to that Pro Tools output pair is indicated by a check mark.
Hardware Setup dialog for 96 I/O, Main page
6 Repeat the above steps to select additional
output destinations. The only limit to output choices is the number of outputs available in your system.

Installing Pro Tools Hardware

To install HD-series hardware, you first install Pro Tools|HD cards, then for systems with more than one card, connect the cards with a TDM FlexCable.

Installing the Pro Tools|HD Cards

This section shows how to install Pro Tools|HD cards into a Macintosh computer. To install cards into an expansion chassis, see the Ex- panded Systems Guide.
HD Process card
The HD Process card includes a single DigiLink port for connecting up to 32 additional chan­nels of audio input and output to your Pro Tools|HD system (up to a maximum of 96 channels).
The DigiSerial port on an HD Process card does not offer any functionality
TDM FlexCable
The TDM FlexCable is used to connect a pair of cards in your Pro Tools system so they can share data along the TDM bus. Additional FlexCables are required to connect additional cards. One FlexCable comes with each HD Accel card.
The TDM FlexCable is a flexible printed circuit board with delicate traces. Do not overbend, twist, or pinch the cable. Doing so may cause unpredictable behavior in Pro Tools as well as harm to your system.
To install Pro Tools cards:
1 Turn off your computer and any peripherals.
Leave your computer’s power cable plugged in so the computer is grounded.
2 Disconnect all cables attached to the com-
puter (such as hard drives, displays, USB and FireWire connections) except for the power ca­ble.
3 Open the computer case.
Before handling any card, discharge static electricity from your clothes or body by touching a grounded metal surface, such as the power supply case inside your computer.
4 Remove the metal access port cover behind
the PCI slot you want to use by removing the screw and sliding the cover out from the access port.

• Secure the card in place with the screw you removed earlier, and close the computer.
• Skip to “Connecting Audio Interfaces” on page 45.
Getting Started with HD 42
7 Install the first HD Accel card (if any) in the
second PCI slot.
8 Install any remaining HD Accel cards in the
remaining consecutive PCI slots.
9 Install any HD Process cards in the remaining
consecutive PCI slots.
10 If you are installing a SCSI HBA card, install
it in the highest-numbered remaining slot.
Do not use SampleCell hardware cards in a Pro Tools|HD system.
Check to be sure that your cards are installed in the following order, starting with the lowest nu­meric slot:
• Display card for your computer monitor
• HD Core card
• HD Accel cards
• HD Process cards
• Digidesign-approved video capture card
• SCSI host bus adapter (HBA) card
The above guidelines may include optional cards not present in your system.
11 Secure each card in place with the slot access
port screws you removed earlier.
The PCI slot numbering in your computer deter­mines whether you will be working right-to-left, or left-to-right when connecting cards. Refer to the instructions below for your model of com­puter.
To connect HD cards with the TDM FlexCable on the Power Macintosh “Mirrored Door” G4:
1 Shape the FlexCable before installing it on
your HD cards by grasping the cable with both hands and moving the Port B portion of the ca­ble straight towards you and inwards, as shown below. Do not bend the cable more than you need to, as you may damage the traces in the ca­ble.
Preparing TDM FlexCable for installation
2 Slide the FlexCable into the notch of the first
card, so that the Port B connector of the FlexCa­ble can be aligned with Port B of the first card; and the Port A connector of the FlexCable can be aligned with Port A of the second card, as shown below.

Connecting Pro Tools|HD Cards

If you are installing a Pro Tools|HD 2 Accel, HD 3 Accel, or an expanded HD system, con­nect the HD cards with TDM FlexCables.
Each HD card has two ports along the top of the card, labeled Port A and Port B. The FlexCable has two connectors, also labeled Port A and Port B, to ensure proper connection. Data com­munication across multiple HD cards is achieved by connecting Port B of the first card to Port A of the next card with a TDM FlexCable.

6 Close the computer case.
Each HD card supports up to 32 channels. To get a full 32 channels of I/O from one card, you can connect, or daisy-chain, a second 16-channel HD I/O to the first HD I/O that is connected directly to the HD card.
Pro Tools|HD supports up to a maximum of eight 192 I/Os, 192 Digital I/Os, or 96 I/Os. Up to four 96i I/Os can be used simultaneously.
For examples of connecting multiple HD I/Os, see Figure 3 and Figure 4 on page 48.
HD audio interfaces need room at their sides to maintain proper air flow for cool­ing. It is important to leave room for air in­take and ventilation on the sides of the unit. Do not block the sides of the unit or discon­nect the internal fan. If the units are rack­mounted in a case, remove the case lids or doors before operating the system. Failure to do so can result in the units overheating very quickly, which can permanently dam­age sensitive components.
Legacy audio interfaces can also be connected to the 192 I/O, 192 Digital I/O, or 96 I/O (the 96i I/O does not support Legacy interfaces). These include: 888|24 I/O, 882|20 I/O, 1622 I/O, 24-bit ADAT Bridge I/O, and the orig­inal ADAT Bridge I/O. The original 888 I/O and 882 I/O interfaces are not supported with Pro Tools|HD.
Chapter 3: Macintosh Configuration 45
To connect HD audio interfaces:
1 If you are using a single 192 I/O,
192 Digital I/O, 96 I/O, or 96i I/O, connect its Primary Port to the HD Core card with the Dig­iLink cable provided with the HD Core card. You must attach at least one 192 I/O, 192 Digital I/O, 96 I/O, or 96i I/O to your sys­tem in order for Pro Tools to launch.
If you have at least one 192 I/O or 192 Digital I/O in your system configura­tion, it must be connected to the HD Core card as the primary interface.
2 Connect additional HD audio interfaces to
subsequent Digidesign audio cards, or daisy­chain your I/Os (by connecting the Primary Port of the secondary I/O to the Expansion Port of the primary I/O).
4 If you are connecting a Digidesign Legacy au-
dio interface (such as an 888|24 I/O, 882|20 I/O, 1622 I/O, or Digidesign ADAT Bridge I/O), con­tinue with “Connecting an Additional 16 Chan­nels of Audio with Legacy Audio Interfaces” on page 46. (The 96i I/O does not support Legacy interfaces.)
Connecting an Additional 16 Channels of Audio with Legacy Audio Interfaces
Each 192 I/O, 192 Digital I/O, and 96 I/O can support 16 channels of audio to and from Digidesign Legacy I/Os. (The 96i I/O does not support Legacy I/O.) These include the 888|24 I/O, 882|20 I/O, 1622 I/O, 24-bit ADAT Bridge I/O, and the original ADAT Bridge I/O. The original 888 I/O and 882 I/O interfaces are not supported with Pro Tools|HD.
If you are connecting both 192 I/O (or 192 Digital I/O) and 96 I/O audio interfaces to your system, connect the 192 I/O (or 192 Digital I/O) to your HD Core card, followed by any additional 192 I/O (or 192 Digital I/O) interfaces connected to the next highest-prior­ity cards. Then connect 96 I/O interfaces to sub­sequent cards, or to other interfaces, then con­nect 96i I/O interfaces.
You can also connect a single HD I/O to each HD card in your system using the provided DigiLink cables. There is no advantage to this configura­tion over daisy-chaining I/Os.
3 If you are using two or more HD audio inter-
faces, connect the Loop Sync Out of each inter­face to the Loop Sync In of the next interface with the BNC cables included in your HD I/O packaging. Then, connect the Loop Sync Out of the last interface to the Loop Sync In of the pri­mary interface.
To connect Digidesign Legacy audio interfaces:
1 Connect the “MIX card” end of the peripheral
cable that came with your Legacy audio inter­face (60-pin side) to the Legacy Port on the pri­mary HD audio interface. Connect the other end to the Computer Port on the Legacy audio interface.
Getting Started with HD 46
2 Connect any additional Legacy audio inter-
faces in the same manner, to HD audio inter­faces connected directly to HD cards.
– or –
If you are using a Y cable (Legacy 16-channel pe­ripheral cable adapter), connect this to the Leg­acy port first, then connect the audio interface peripheral cables to Port A and Port B of the Y cable.
“A” to first Legacy I/O
Optional 16-channel peripheral cable adapter
3 To properly clock the Legacy audio interface,
“B” to second Legacy I/O
to Legacy Port on HD audio interface
connect the Ext. Clock Out port on the HD I/O to the Slave Clock In on the Legacy audio inter­face. The Legacy audio interface will switch to Slave mode once the proper clock is outputting from the HD I/O. Always use the Ext. Clock Out port of the same I/O to which the Legacy audio interface is attached.
You cannot slave more than two MIX-series au­dio interfaces to a single HD-series audio inter­face. If you have a third MIX-series audio inter­face, supply its 256x clock from the HD I/O to which its 60-pin cable is attached.
To ensure the proper functioning of Legacy audio interfaces (such as an 888|24 I/O or 882|20 I/O), launch Pro Tools and declare the legacy audio interfaces in the Hardware Setup dialog before turning them on. Then quit Pro Tools, shut down your computer, turn on your audio interfaces, and turn on your computer.
Before you turn on and configure your Leg­acy audio interface, turn down the volume of output devices. Very loud digital noise may be emitted before the Legacy audio in­terface is initialized.
If you are using the Y cable to connect multiple MIX-series audio interfaces, you must also con­nect the Slave Clock Out of the first Legacy in­terface to the Slave Clock In of the second Leg­acy interface with the provided BNC cable. You cannot clock more than two MIX-series audio interfaces from a single HD-series audio inter­face. If you have a third MIX-series audio inter­face, supply its 256x clock from the HD I/O to which its 60-pin cable is attached (either your second audio interface, or directly to an HD Accel or HD Process card).

Within DigiTest, the Firmware Update page tells you the firmware version for the selected pe­ripheral and lets you update to a newer version, if necessary.
To update the firmware in an HD-series audio interface:
1 Quit Pro Tools if it is running.
2 Locate and double-click the DigiTest applica-
tion on your hard drive.
Getting Started with HD 52
3 Click the Firmware tab.
4 Choose a card slot from the pop-up menu. If
any HD audio interfaces are connected to the card, the Primary or Secondary options will be­come available in the HD Peripheral section of the Firmware page.
The authorization code is located on the inside cover of this guide.
Configuring Pro Tools
If any connected interfaces are not recognized, check the connections and power to each inter­face and click Re-Scan.
5 Under HD Peripheral, select Primary or Sec-
ondary to view the firmware version for the cor­responding interface. The firmware version is displayed just below the HD Peripheral section of the Firmware page.
6 If the firmware version is not current, click Be-
gin Update to update the firmware in the se­lected audio interface.
The status of the firmware update process is dis­played in the status area at the bottom of the Firmware page.
7 After the update process is complete, click
Quit to close DigiTest.

Launching Pro Tools

When launching Pro Tools the first time, you are prompted to enter an authorization code to validate your software.
To validate Pro Tools software:
1 Double-click the Pro Tools application, lo-
cated in the Pro Tools folder, inside the Digide­sign folder.

Pro Tools System Settings

Pro Tools 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.
Voice Count
The Number of Voices setting lets you control the number of voices available on your system. For example, the default number of voices on an HD 1 system is 48 voices, using one DSP (at sam­ple rates of 44.1 kHz or 48 kHz).
Changing the number of voices affects DSP usage, the total number of voiceable tracks, and overall system performance.
Depending on the current sample rate and the number of HD Core and HD Process cards in your system, you will have different choices for voice count.
2 Enter the authorization code in the dialog
when prompted, making sure to observe any spaces, then click Validate.
Chapter 3: Macintosh Configuration 53
To change the Voice Count:
1 Choose Setups > Playback Engine.
2 Select the number of voices and DSPs to allo-
cate for voicing by choosing a value from the Number of Voices pop-up menu.
Playback Engine dialog for Pro Tools|HD system
• Select higher voice numbers when your Digidesign cards are the only PCI cards in your computer, or when you are using an expansion chassis to run higher track counts (such as 64 tracks at 96 kHz) and you want more voices per DSP (such as 16 voices per DSP at 96 kHz). These settings use fewer DSP chips for mixing (leaving more available for plug-ins) but place the highest processing load on each allocated chip.
• Select medium voice numbers when your Digidesign cards are in an expansion chas­sis, or when you are using other PCI cards along with Digidesign cards. These settings generally provide an optimum balance be­tween number of chips needed for voicing, and the processing load placed on each.
• Select minimum voice numbers if you are using high-bandwidth PCI cards (such as video capture cards) along with your Digidesign cards. These settings place the lightest processing load on each allocated DSP chip, but generally require that more DSP chips be dedicated to voicing and mix­ing (leaving fewer available for plug-ins).

3 Click OK.
Hardware Buffer Size
The Hardware Buffer Size (H/W Buffer Size) con­trols the size of the hardware cache used to han­dle host processing tasks such as Real-Time Au­dioSuite (RTAS) plug-ins.
• 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 affect the accuracy of plug-in automation, mute data, and timing for MIDI tracks.
Getting Started with HD 54
To change the Hardware Buffer Size:
1 Choose Setups > Playback Engine.
2 From the H/W Buffer Size pop-up menu, select
the audio buffer size, in samples.
3 Click OK.
CPU Usage Limit
The CPU Usage Limit controls the percentage of CPU resources allocated to Pro Tools host pro­cessing tasks. The maximum CPU Usage Limit is 85 percent for single-processor computers, and 99 percent for multi-processor computers. (The 99 percent setting dedicates one entire processor to Pro Tools.)
DAE Playback Buffer Size
The DAE Playback Buffer Size determines the amount of memory DAE uses to manage disk buffers, which affects system performance.
• Higher DAE Playback Buffer Size settings can allow for a higher density of edits in a session. However, a higher setting can cause a time lag to occur before playback or recording begins. It can also cause a time lag to occur when you are ed­iting during playback.
• Lower DAE Playback Buffer Size settings can improve playback and recording initiation speed. However, a lower setting can make it dif­ficult for slower hard drives to play or record tracks reliably.
To change the CPU Usage Limit:
1 Choose Setups > 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.
3 Click OK.
• 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.
• Lower CPU Usage Limit settings limit the ef­fect 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.
Increasing the CPU Usage Limit may slow down screen responses on slower computers.
To change the DAE Playback Buffer Size:
1 Choose Setups > Playback Engine.
Playback Engine dialog for Pro Tools|HD system
2 From the DAE Playback Buffer pop-up menu,
select a buffer size. Memory requirements for each setting are shown at the bottom of the Playback Engine dialog.
3 Click OK.
4 If Pro Tools needs more system memory for
the DAE Playback Buffer, it will prompt you to restart your computer.
Chapter 3: Macintosh Configuration 55
System Memory Allocation
When you start your computer, Pro Tools auto­matically reserves a portion of system memory for the DAE Playback Buffer. This reserved mem­ory is unavailable to other applications, even if Pro Tools is not running.
You can set Pro Tools to reserve only the mini­mum amount of required memory, so that more system memory is available to other applica­tions.
To minimize system memor y allocation:
1 Choose Setups > Playback Engine.
2 Select the “Minimize System Memory Alloca-
tion” option.
3 Click OK.
3 Choose the sample rate from the Sample Rate
pop-up menu.
4 Click OK.
Sample Rates and Expanded Systems
With 176.4 kHz and 192 kHz sample rates, as many as four HD-series cards can be used. Any additional cards (up the total system maximum of seven cards) will switch to Inactive mode. The cards and any attached peripherals will become active when the system (or a session) sample rate is set to 96 kHz or lower. See also “Offline Peripherals” on page 61
Clock Source
The Pro Tools Hardware Setup dialog allows you to select the Clock Source for the system.
4 Restart your computer.

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.
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. (See
To change the default Sample Rate:
1 Make sure that no Pro Tools session is open.
2 Choose Setups > Hardware Setup.
“Starting a Session” on page 71.)
Internal If you are recording an analog signal di­rectly into Pro Tools, you will usually use the Pro Tools Internal clock source.
External If you are transferring material into Pro Tools from an external digital device, or if you utilize a common house clock signal, you will synchronize Pro Tools to that digital device or common signal. Depending on your audio in­terface, external options can include AES/EBU [Encl], S/PDIF, Optical [Encl], AES/EBU 1–8, TDIF, ADAT, and Word Clock. For details, refer to the Pro Tools Reference Guide or the guide for your audio interface.
To select the Clock Source:
1 Choose Setups > Hardware Setup.
2 Choose the clock source from the Clock
Source pop-up menu.

3 Click OK.
Identifying Audio Interfaces
Your digital input device must be connected and powered on for Pro Tools to synchro­nize to it. If your input device is not powered on, leave the Clock Source set to Internal.
Configuring Audio Interfaces
Pro Tools|HD audio interfaces support 16 chan­nels of simultaneous I/O and multiple I/O for­mats (including analog, AES/EBU, ADAT Opti­cal, S/PDIF, and TDIF).
Hardware Setup dialog for 192 I/O, Main page
The Main page of the Hardware Setup dialog is where you define which physical inputs and outputs on your audio interface are routed to available inputs and outputs in Pro Tools. You can think of this window as a patchbay that al­lows you to route any of the inputs or outputs on your HD-series audio interfaces to channel assignments in the Pro Tools mixer.
The Main page also provides controls for defin­ing whether Expansion Port or Legacy Port pe­ripherals are active.
To configure the interfaces in your system, you select each interface in the Peripherals list and set the parameters for that interface.
If you have multiple audio interfaces of the same type connected to your system, before you make audio connections to them, you should confirm the identity of each interface. This en­sures that you choose the appropriate interface in the Peripherals list when you define its inputs and outputs in the Hardware Setup dialog.
To identify audio interfaces in your system:
1 Choose Setups > Hardware Setup.
2 From the Peripherals list, select an audio inter-
face connected to your system.
Use the Up and Down Arrow keys to scroll though the Peripherals list in the Hardware Setup dialog.
3 Make sure the Main page tab is chosen.
4 Select the Identify option, located in the lower
left corner of the Hardware Setup dialog. This il­luminates all the LEDs on the front panel of the selected audio interface.
5 Make a note of which interface in your studio
setup corresponds to the identified interface.
6 Repeat the above steps for each additional au-
dio interface in your setup.
Legacy audio interfaces must be initialized in the Peripherals list before they can be identified. See
Interfaces” on page 61
“Configuring Legacy Audio
.
To configure HD audio interfaces:
1 Choose Setups > Hardware Setup.
2 From the Peripherals list, select an audio inter-
face connected to your system.

4 From the Clock Source pop-up menu, select
the appropriate clock source for the interface.
5 If you want to send clock output to other de-
vices attached to the audio interface, select the appropriate output from the Ext. Clock Output pop-up menu.
If the Legacy I/O Port is enabled (and not the Expansion I/O Port) then the Ext. Clock Output automatically switches to Slave256x. To reset the Ext. Clock Output to Word Clock, change the Port Settings back to Expansion I/O, then se­lect the Legacy audio interface in the Peripherals list, and set it to No Interface in the Interface pop-up menu. (The 96i I/O does not support Legacy I/O.)
6 Select which digital I/O port on your audio in-
terface enclosure is active by selecting an option under Digital Format. Depending on the type of interfaces in your system, choices include AES/EBU, S/PDIF, and Optical (S/PDIF). Select­ing Optical (S/PDIF) resets the Optical I/O port (which is, by default, eight channels of ADAT Optical I/O) to two channels of S/PDIF Optical I/O. (The 96i I/O supports stereo S/PDIF RCA digital input and output only.) For more information about HD enclosure and card ports, refer to the guide for your audio interface.
7 For S/PDIF compatibility with Tascam DA-30
DAT recorders, select the Tascam option under S/PDIF Format.
8 From the Input and Output channel pop-up
menus, select the physical ports (such as Analog 1–2 or Optical 1–2), that will be routed to the corresponding Pro Tools input and output channels (such as Ch 1–2, Ch 3–4), listed on the left side of the Main page. (This feature is not available with the 96i I/O.)
Inputs and outputs of similar format are differ­entiated in the input and output channel pop­up menus. For example, the AES/EBU inputs and outputs in the 192 I/O enclosure are listed as AES/EBU [Encl], while the AES/EBU inputs and outputs on the factory-installed Digital I/O card are listed (in pairs) as AES/EBU 1–2, AES/EBU 3–4, AES/EBU 5–6, and AES/EBU 7–8. For 192 I/Os equipped with the optional Digital I/O Card, the additional AES/EBU I/O ports on the optional card are listed as AES/EBU 9–10, AES/EBU 11–12, AES/EBU 13–14, and AES/EBU 15–16.
Refer to your peripheral’s guide for configu­ration details and restrictions. For example, the Optical 1–8 channels (on the 192 I/O enclosure) will not be available at session sample rates of 88.2 kHz or higher, while the ports on the 192 I/O Digital I/O card will still be available.
9 Configure controls for your HD audio inter-
face. See “Configuring 192 I/O and 192 Digital I/O Controls” on page 58, “Config­uring 96 I/O Controls” on page 60, and “Con­figuring 96i I/O Controls” on page 60.

Configuring 192 I/O and 192 Digital I/O Controls
To configure controls for a 192 I/O:
1 With the 192 I/O selected in the Peripherals
list, click the Analog In tab for the following op­tions:
Getting Started with HD 58
•You can set your operating level on a chan­nel-by-channel basis by selecting Reference Level +4 dBu or –10 dBV. These settings correspond to two different input connec­tors on the rear of the 192 I/O. Refer to the 192 I/O Guide for more information on set­ting operating levels.
• Each of the analog channels in the 192 I/O has two Input Trims, labeled A and B, for precisely calibrating and switching levels. You can select Input Trim A or B on a chan­nel-by-channel basis. Refer to the 192 I/O Guide for information on setting the rear panel trims.
•You can select Soft Clip on a channel-by­channel basis. The Soft Clip limiter attenu­ates the incoming analog signal, providing extra protection from temporary clipping transients that can cause digital distortion when they exceed the maximum input of the unit. With Soft Clip enabled, 192 I/O supports an additional 4 dB of headroom by rounding off the top 4 dB to the clip point. This is useful for eliminating stray transients or for emulating analog tape sat­uration.
• Each of the analog channels in the 192 I/O has two Output Trims, labeled A and B, re­spectively. You can select Output Trim A or B on a channel-by-channel basis.
Hardware Setup dialog for 192 I/O, Analog Out page

The 96i I/O only supports analog and digi­tal switching for channels 1–2, and only from within the Hardware Setup and I/O Setup dialogs. The 96i I/O does not support path remapping within I/O Setup.
Configuring Legacy Audio Interfaces
Before you can configure a Legacy audio inter­face, it must first be initialized in Hardware Setup.
After you select the type of Legacy audio inter­face, the Main page updates with controls that can be configured.
7 Repeat the above steps for each additional
Legacy audio interface.
For more information on Hardware Setup controls for each I/O, refer to its
guide.
Offline Peripherals
When a Legacy audio interface and HD periph­eral are connected to your primary HD periph­eral, only one can be online at a time. An offline peripheral is indicated by brackets in the Periph­erals List of the Hardware Setup dialog. For ex­ample, if you have a 96 I/O and an 882|20 con­nected to a 192 I/O, and the 96 I/O is offline, it will appear in the Peripherals List as “[96 I/O].”
To initialize a Legacy audio interface:
1 Make sure to lower the volume of your output
devices. Very loud digital noise may be emitted before the Legacy audio interface is initialized.
2 Turn on your Legacy audio interface.
3 From the Peripherals list, choose the primary
audio interface (the interface to which your Leg­acy audio interface is connected).
4 In the Main page of the Hardware Setup dia-
log, select the Legacy I/O option under Port Set­tings.
5 In the Peripherals list, “No Interface” is listed
twice, directly below the primary audio inter­face. Click the first “No Interface.” An Interface pop-menu appears in the Hardware Setup dia­log, listing supported I/O choices.
6 From the Interface pop-up menu, select the
type of Legacy audio interface you connected. (If your Legacy interface does not appear, check connections and repeat from step 1, above. See also “Offline Peripherals” on page 61.)
Pro Tools|HD peripherals (and any attached Legacy I/Os) will also go offline if the primary audio interface to which they are attached is of­fline, or if the HD card to which they are at­tached is made inactive. See “Sample Rates and Expanded Systems” on page 56 for more infor­mation.
Configuring I/O Setup
The I/O Setup dialog provides a graphical repre­sentation of the signal routing for each con­nected audio interface, with controls to route physical ports to Pro Tools inputs and outputs. These controls mirror the routing controls found in the Hardware Setup dialog—changes made to physical routing in one dialog are al­ways reflected in the other. The I/O Setup dialog also lets you label and map Pro Tools input, out­put, insert, and bus signal paths.
Chapter 3: Macintosh Configuration 61
Pro Tools comes with default I/O Setup settings that will get you started. You only need to go to I/O Setup if you want to remap or rename the default I/O paths or if you change your system hardware (for example, adding an expansion card to a 192 I/O).
Refer to the Pro Tools Reference Guide for more information on setting up I/O paths.
To configure I/O routing in I/O Setup:
1 Choose Setups > I/O Setup.
2 Click the Input or Output tab to display the
corresponding connections.
7 Click OK.
3 To change the name of a path or subpath,
double-click directly on the Path Name, type a new name for the path, and press Return.
4 To change the destination of an Input or Out-
put path or subpath, click directly on an Input or Output Selector for an interface channel pair, just below an audio interface icon. (This feature is not available with the 96i I/O.)
5 From the pop-up menu, select a physical port
pair (such as Analog 1–2), to route to the corre­sponding Pro Tools channel pair (such as A 1–2) in the Path Name column on the left.
6 Repeat the above steps for additional channel
pairs.
I/O Setup dialog for a Pro Tools HD system
Routing a Pro Tools Output Pair to Multiple Destinations
Pro Tools channel pairs can be routed to multi­ple outputs on your Digidesign audio interface through the Hardware Setup dialog.
For example, if you assign both Analog 1–2 and Analog 3–4 interface outputs to Pro Tools Out­put pair 1–2, when you send a signal to Pro Tools Outputs 1–2, that signal will be routed simultaneously to both pairs of output ports on your audio interface.
This lets you send the same signal (such as a ste­reo pair, a stem mix, or a multichannel mix) to multiple destinations (such as multiple master­ing devices).
To route a Pro Tools output channel pair to multiple audio interface output ports:
1 Choose Setups > Hardware Setup.
2 From the Peripherals list, select an interface.
3 Click the Main tab.
4 Select an output pair from an Output pop-up
menu.
Getting Started with HD 62
5 Control-click the same pop-up menu to
choose an additional output pair.

Connecting Your Studio

This chapter provides general information on connecting Pro Tools to your system, including digital equipment, effects units, MIDI gear, and SMPTE synchronization devices.
Refer to the 192 I/O Guide, 192 Digital I/O Guide, 96 I/O Guide, or 96i I/O Guide for specific details regarding:
• Front and back panel connectors and indica­tors
• Installation of optional expansion I/O cards (192 I/O only)
HD audio interfaces need room at their sides to maintain proper air flow for cool­ing. Do not block the sides of the unit or dis­connect the internal fan. If the units are rack-mounted in a case, remove the case lids or doors before operating the system. Failure to do so can result in the units over­heating very quickly, which can perma­nently damage sensitive components.

Setting Up Your Studio

Figure 5 illustrates a typical studio setup, with a 192 I/O connected to a mixing console, effects and other equipment.

192 I/O

96i I/O

The 192 I/O features two DB-25 breakout con­nectors for two sets of eight inputs each, at +4 dBu and –10 dBV respectively.
There are no –10 dBV outputs, however; analog outputs break out from a single DB-25 output at +4 dBu operating levels.
When driving unbalanced lines on the 192 I/O output card, leave the negative “–” terminals disconnected. Failure to do so will result in noisy outputs.
The 192 I/O requires a custom DB-25 snake. Digidesign sells several different DigiSnake (DB-
25) cables for this purpose. Contact your dealer or Digidesign for more information.

192 Digital I/O

The 192 Digital I/O features two DB-25 breakout connectors for two sets of eight AES/EBU or TDIF inputs and outputs, along with a pair of ADAT Optical ports.
The 192 Digital I/O requires a custom DB-25 snake. Digidesign sells several different DigiS­nake (DB-25) cables for this purpose. Contact your dealer or Digidesign for more information.

96 I/O

The 96 I/O analog connectors are TRS 1/4-inch with TIP wired hot (or “+”), RING cold (or “ and SLEEVE ground. If connecting to unbal­anced loads, use unbalanced TS cables.
There is one bank of eight inputs (software-swit­chable between +4 dBu and –10 dBV line levels on a line-by-line basis).
There is one bank of eight outputs (that use +4 dBu line levels).
”),
The 96i I/O analog connectors are balanced TRS 1/4-inch with TIP wired hot (or “+”), RING cold (or “
”), and SLEEVE ground. If connecting to
unbalanced loads, use unbalanced TS cables.
The 96i I/O provides 16 inputs and two outputs. Inputs 1–4 feature variable, multi-level input sensitivity, controllable from within Pro Tools (from –12 dBV to +4 dBu). Inputs 5–16 provide a choice of two fixed operating levels (–8 dBV or +4 dBu).
Outputs 1–2 are selectable between –10 dBV and +4 dBu.

Connecting Equipment with Digital Audio Ins and Outs

Each Pro Tools HD audio interface includes at least one AES/EBU, S/PDIF, or ADAT digital op­tion. For example, the 192 I/O includes addi­tional AES/EBU and optical ports, as well as TDIF, dual-wire AES/EBU at 192 kHz, and sam­ple rate converters. The 96i I/O provides two channels of S/PDIF only. (See the documenta­tion for your audio interface for details.)
The following example provides basic setup guidelines for connecting Pro Tools to a DAT re­corder. For detailed information for recording to and from an ADAT, see “Recording To and From Digital Devices” on page 84.
To connect your Pro Tools system to a DAT recorder:
1 Connect the AES/EBU or S/PDIF output on the
enclosure of your HD audio interface to the AES/EBU or S/PDIF input of your DAT deck. By default, this port is assigned to Pro Tools Output 1–2.
Getting Started with HD68
2 Connect the AES/EBU or S/PDIF input on the
enclosure to the AES/EBU or S/PDIF output of your DAT deck. Route the digital input to Pro Tools inputs in the Hardware Setup dialog.
You can route any of the physical input or output pairs to any of the input and output channel assignments in the Pro Tools mixer. (The 96i I/O does not support input mapping, however.) For more information see the Pro Tools Reference Guide.

Connecting Effects Units

The 192 I/O, 192 Digital I/O and 96 I/O let you connect analog or digital effects units to your Pro Tools system, and use them as inserts or make them the destination for effects sends and returns. (The 96i I/O supports a single pair of hardware inserts using channels 1–2. See the 96i I/O Guide for more information.)
Five inserts are available on each audio channel. Each insert can be a hardware insert (or software plug-in), and can be mono or stereo.
When using a hardware insert, you can connect the device to matching inputs and outputs on your system. For example, a stereo insert could use outputs 7–8 and inputs 7–8 for the sends and returns, respectively. Routing the physical inputs and outputs of the interface to Pro Tools inputs and outputs can be done in either the Hardware Setup dialog or I/O Setup dialog. From I/O Setup, inserts can also be defined, and their channels mapped to audio interface channels. (For more information, see the Pro Tools Refer- ence Guide).
You can also connect effects units to your sys­tem by using any analog or digital inputs and outputs as Auxiliary Inputs and Outputs for ef­fects sends and returns. Once an effects unit is attached this way, you can send a variable amount of a track’s output to the effects unit us­ing a send fader in Pro Tools.
Five separate send controls on each Pro Tools track allow you to route audio to any of the available outputs connected to your system or through any of the 64 internal busses in the Pro Tools TDM Mixer. Outputs can be returned to mono or stereo Auxiliary Inputs for auto­mated mixing or processing.
When you are using an effect in this send and return type of configuration, make sure the unit’s internal mix or balance between direct (unprocessed) and wet (effected) signal is set so that only the processed signal is returned to Pro Tools. On most effect units, a balance set­ting of 100% (completely wet) is the appropriate setting.
If you’ve been using an effects unit in an instru­ment setup, such as a guitar effects rack, you’ll probably find the balance to be below 50%. If the unit has separate dry and effect level knobs, turn dry level control off. If you don’t do this, the dry, unprocessed signal will be present in an effect’s output along with the desired processed sound, and you’ll have trouble accurately con­trolling the effect balance in your final mix.

Connecting Effects Units Digitally

To use your audio interface’s inputs and outputs as effects sends and returns to a digital effects device, set your interface’s Clock Source to Inter­nal in the Hardware Setup dialog (unless it is ref­erenced to another clock source or peripheral). You should then set your digital effects devices to accept an external digital clock so that they
Chapter 4: Connecting Your Studio 69
will synchronize themselves to Pro Tools. Make sure you set the channel pair to the digital input in the Hardware Setup dialog (or I/O Setup dia­log).

Connecting MIDI Devices

By adding a compatible MIDI interface to your system, you can take advantage of all the MIDI features of Pro Tools, including recording and editing MIDI tracks, and synchronizing to MIDI Time Code or MIDI beat clock.
See Appendix E, “Configuring AMS (Mac OS X Only)” for information on configur­ing Audio MIDI Setup and your MIDI devices.
For information on configuring a MIDI con­trol surface for use with Pro Tools, see the electronic PDF version of the Pro Tools MIDI Control Surfaces Guide (included with Pro Tools).
To connect MIDI devices to your system:
1 Connect the MIDI interface to your computer
according to the MIDI interface’s documenta­tion.
2 Install any MIDI driver software required by
the MIDI interface. (Once you have installed your MIDI interface hardware and software, confirm that it is working properly using the procedure given in the interface’s documenta­tion.)

Connecting SMPTE Synchronization Devices

If you intend to synchronize Pro Tools to exter­nal devices with SMPTE, your system must be connected properly. For details on SMPTE and synchronization, see the Pro Tools Reference Guide or the SYNC I/O Guide.

Digidesign SYNC I/O

Digidesign’s SYNC I/O is a multi-purpose syn­chronization peripheral that provides all the functions and connections needed to synchro­nize to a variety of devices with Pro Tools.
SYNC I/O lets you synchronize Pro Tools to LTC, VITC, and Bi-Phase/Tach, or internal for positional reference (time code), and supports all major clock references.
SYNC I/O integrates into the Loop Sync config­uration of an HD-series system, offering ex­tremely fast lockup, near-sample accurate syn­chronization, and an exceptionally low-jitter clock. These features provide professional per­formance and maximum audio fidelity under a wide range of synchronization conditions.
For more information, refer to the SYNC I/O
Guide.

Rulers
Pro Tools provides several different rulers to se­lect as the timebase for your session. Timebase Rulers, displayed along the top of the Edit win­dow, include Bars:Beats, Minutes:Seconds, Sam- ples, Time Code, and Feet.Frames. The current timebase determines the format of the Main counter, and provides the basis for the Edit win­dow Grid.
For post production, select either Time Code or Feet.Frames as your session Timebase in the Rul­ers view.
To select a Timebase Ruler:
Click the name of the ruler at the top left side
of the Edit window (Bars:Beats, Minutes:Sec­onds, Samples, Time Code, or Feet.Frames).

Setting a Tempo

You can set the tempo for your session using Tempo Events, or using the MIDI tempo con­trols in the expanded Transport window.
To insert a tempo event:
1 Choose Windows > Show Tempo/Meter.
2 At the top of the Tempo/Meter Change win-
dow, choose Tempo Change from the pop-up menu.
3 Enter the BPM value you will use for the ses-
sion and set the Location to 1|1|000 (so the in­serted tempo event replaces the default tempo).
4 To base the BPM value on different note value
(such as an eighth-note rather than the default quarter-note), select a note value.
5 Click Apply to insert the new tempo event.

Using the Click

Pro Tools provides a MIDI Click option that lets you use the Digidesign Click Plug-In (Pro Tools 6 only), or an external MIDI device to play a click. This feature can be turned on and off in the Transport window (or in the MIDI menu), and is configured from the MIDI Click Options dialog.
If you do not intend to use the Digidesign Click plug-in, skip to “Configuring MIDI Click Op­tions” on page 73.

Saving Sessions

As you build a session by adding tracks and changing session controls, you will want to save your work. Pro Tools provides three ways to save sessions.
To save a session:
Choose File > Save Session, Save Session As, or
Save a Session Copy In.
Save Session Saves the currently open session file, leaving it open for you to continue work­ing.
Save Session Copy In Saves copies of the session file and the files that you are using in the cur­rent session. This can be useful for creating a fi­nal copy of the session that does not include au­dio files or fades you are no longer using.

System Resources and Settings

You can change specific Pro Tools system set­tings in the Playback Engine dialog to optimize system performance.
Playback Engine Dialog
The Playback Engine dialog lets you adjust sys­tem buffer sizes and allocate CPU processing power to Pro Tools.

Audio and MIDI Regions Lists
For more information on Regions Lists, refer to the Pro Tools Reference Guide.
Pro Tools lets you import existing audio files from disk, as well as import tracks from an audio CD (Macintosh only). This is very useful if you have audio files already recorded to disk or if you are working with CD-based sample libraries that you want to use in a new session.
Pro Tools 6 provides DigiBase and DigiBase Pro, which provide drag and drop support for im­porting audio, tracks, and sessions, as well as im­porting from audio CD.

Importing using DigiBase

To import audio files into the current session:
1 Make sure the drive (volume) containing the
desired files is mounted and available. If import­ing from an audio CD, insert the disc into your CD-ROM drive.
2 Navigate to the desired files to display them in
an available DigiBase browser.
3 Drag and drop items from the DigiBase
browser to a track, to the timeline, or to the Au­dio Regions List.
• Drop audio files or session files into exist­ing tracks to spot (place) the files where you drop them. Dropping session files will display the Import Session Data dialog where you can specify session attributes to import.
• Drop audio files or session files to a blank (non-track) area of the Edit window to add the audio as a new tracks.
– or –
Chapter 5: Working with Pro Tools 81
•To import directly into the session’s Audio Regions List (without spotting audio, im­porting tracks, or creating new tracks) drop items into the Audio Regions List. (You cannot drag and drop video or MIDI files.)
For more information, see the DigiBase and DigiBase Pro Guide.

Importing Audio Files or Regions

To import audio files or regions from disk:
Choose File > Import Audio to Track to import

5 Navigate to a destination for the imported au-
dio, and click Choose.
Pro Tools converts the CD audio track to the ses­sion’s audio file format, bit depth, and sample rate, and saves it on your hard drive.
The imported audio file appears in the Audio Re­gions List. From there you can drag the region to a track in your session.

Basic Recording

This section describes how to record audio and MIDI into Pro Tools.
Choose Import Audio from the Audio Regions List pop-up menu to import files and regions to the Audio Regions List only.
For more information on importing audio into sessions, refer to the Pro Tools Refer­ence Guide.
To import a CD audio track (Pro Tools 6.x):
1 Insert an audio CD into your CD-ROM drive.
2 Do any of the following:
• Choose File > Import Audio to Track to im­port files and regions to new audio tracks (they will also appear as regions in the Au­dio Regions List).
• Choose Import Audio from the Audio Re­gions List pop-up menu to import files and regions to the Audio Regions List only.
• Choose Movie > Import Audio From Other Movie.
3 Locate and select the audio track to be im-
ported, then click Open.
4 In the Track Import Window, click OK.

Routing Audio to a Track

To route audio to a track:
1 Verify the connections to your instruments.

2 Choose File > New Track, specify 1 Mono Au-
dio Track, and click Create.
3 In the Mix window, click the Input Selector on
the new track.
Analog inputs
Routing an input to a mono track
Getting Started with HD82
From the pop-up menu, select the input you want to record. For example, select A 1 if your audio source is plugged into the first analog in­put on your audio interface. The menu displays the names of the inputs as defined in the I/O Setup dialog.

Setting Levels

Adjust the level of the input at the source (in­strument, mic pre-amp, or mixer) to set Pro Tools recording levels. The key to setting proper input levels is to get a signal as loud as possible without creating digital clipping. Sig­nals that get close to the top of the meter in Pro Tools use more of the full bit range (the 16 or 24 bits that make up each audio sample). The more you are able to maximize use of this bit range without clipping, the better your sound quality.
Digital clipping occurs when you feed a sig­nal to an audio device that is louder than the circuitry can accept. Watch the meters in Pro Tools while adjusting input levels to prevent clipping.
Setting Reference Levels
To configure input levels for the 192 I/O:
1 In Pro Tools, choose Setups > Hardware.
2 If using multiple audio interfaces, select an in-
terface in the Peripherals list.
3 In the Interface area, click the Analog In tab.
Hardware Setup, 192 I/O Analog In settings
4 Set the Reference Level for each Input Chan-
nel.
5 Click OK.

Recording an Audio Track

To record an audio track:
1 Click the Record Enable button on a track, as-
sign its input, and set the input levels appropri­ately.
2 Choose Windows > Show Transport to display
the Transport window. Click Return To Zero to start recording from the beginning of the ses­sion. You can also record according to a selec­tion or from the cursor location in the Edit window.
3 Click Record in the Transport window to en-
able recording.
4 Click Play or press the Spacebar to record on
all record-enabled tracks.
To play back a recorded track:
1 Click the track’s Record Enable button a sec-
ond time to take it out of Record mode.
2 Click Play in the Transport window or press
the Spacebar to start playback.
3 Click Stop in the Transport window or press
the Spacebar to stop playback.

Recording To and From Digital Devices

Using a 96i I/O audio interface, you can digitally transfer up to two tracks at a time to or from any S/PDIF-compatible device. Using a single 96 I/O audio interface, you can digitally transfer as many as eight tracks at a time to or from a digi­tal device (such as an ADAT). You can digitally transfer up to 16 tracks on a single 192 I/O or 192 Digital I/O, up to a system maximum of 96 inputs.
Setting Digital Format and Clock Source
Recording to and from digital devices is only slightly different than analog recording.
Before recording from a digital source, make sure you have enabled the appropriate Clock Source and Digital Format in the Hardware Setup dialog. Digital Format defaults to AES/EBU, meaning your HD I/O will listen to the AES/EBU (Encl) In port for digital clock (if any). If you want to record from a DAT machine connected to your S/PDIF RCA inputs, select S/PDIF Format. If you are using multiple HD in­terfaces, be sure to configure the appropriate in­terface in the Hardware Setup dialog.
5 Record your performance.
6 Click Stop in the Transport window or press
the Spacebar when you are finished recording.
Getting Started with HD84
After enabling a different digital format, appro­priate clock signals will become available in the Clock Source selector. If you have multiple in­terfaces, choose the appropriate clock source on each HD I/O.
Using Pro Tools Output Pairs
Because of the way that outputs function in Pro Tools, each track looks for a stereo output pair. In order to record to eight ADAT tracks, you have to send four pairs of Pro Tools tracks (each pair panned hard left and right) to four pairs of ADAT Optical Digital outputs.
Working with 88.2 kHz or Higher Sample Rates
If the session sample rate is 88.2 kHz or higher, ADAT and TDIF input sources can still be used with Digidesign’s 192 I/O, but the sample-rate conversion option must be enabled. 96 I/O and 96i I/O audio interfaces do not have sample rate conversion capability. On the 96 I/O, the ADAT port will go offline with sample rates above 48 kHz. All ADAT and TDIF output ports go of­fline with sample rates above 48 kHz.
When the sample rate conversion option is dis­abled, signal does not pass through the sample rate converter.
To enable sample rate conversion on the 192 I/O:
1 Choose Setups > Hardware in Pro Tools.
2 From the Peripherals list, select the primary
192 I/O audio interface.
3 Click the Digital tab.
4 Select an Input Format (AES/EBU 1–8, ADAT
1–8, or TDIF 1–8).
5 Enable the SR Conversion option for channel
pairs.
Chapter 5: Working with Pro Tools 85
Recording to and from an ADAT
The 192 I/O and 192 Digital I/O each provide 16 channels of ADAT input and output (eight on the chassis, eight on the digital card). These inputs and outputs are numbered 9–16 and 17–24 by default in the Pro Tools Hardware Setup and I/O Setup dialogs.
The 96 I/O provides eight channels of ADAT in­put and output. These inputs and outputs are la­beled Optical 1–8 and ADAT 1–8 by default in the Pro Tools Hardware Setup and I/O Setup di­alogs.
(The 96i I/O does not support ADAT Optical in­put or output.)
To record ADAT tracks into Pro Tools:
1 Connect the Optical Out connector from your
ADAT deck to the Optical In connector on the back of your Pro Tools|HD audio interface.
2 Open or create a session in Pro Tools.
3 Record enable up to eight audio tracks.
8 When playback from the ADAT tape is fin-
ished, click Stop in the Transport window, or press the Spacebar.
To record Pro Tools tracks to an ADAT:

Editing

Pro Tools provides several tools for editing audio and MIDI. In the Edit window, audio and MIDI tracks can be edited into regions or repeated in different locations, to create loops, re-arrange sections or entire songs, or to assemble tracks us­ing material from multiple takes.

Edit Modes

Edit Tools

The Edit mode affects the movement and place­ment of audio and MIDI regions (and individual MIDI notes), how commands like Copy and Paste function, and also how the various edit tools (Trimmer, Selector, Grabber, and Pencil) work.
Pro Tools 6 provides two Grid modes, Abso­lute (standard Pro Tools Grid mode), and Relative. For detailed descriptions of Edit modes, refer to the Pro Tools Reference Guide.
Edit modes and tools (Slip mode, Smart Tool enabled)
Audio and MIDI editing are typically used to:
• Fix or replace mistakes.
• Re-arrange songs and projects.
• Clean up track timing and rhythm by aligning hits to Grid values like bars and beats, time code, or other timebases.
• Create final tracks using selections from mul­tiple takes (also known as a comp tracks).
Edit Modes
Pro Tools has four Edit modes: Shuffle, Spot, Slip, and Grid. The Edit mode is selected by clicking the corresponding button in the upper left of the Edit window.
Edit mode buttons
You can also press F1 (Shuffle), F2 (Slip), F3 (Spot), and F4 (Grid) to set the Edit mode.
Edit Tools
Pro Tools has seven Edit tools: Zoomer, Trim­mer, Selector, Grabber, Scrubber, Pencil, and Smart Tool. Select an Edit tool by clicking it in the Edit window. The Zoomer, Trimmer, Grab­ber, and Pencil tools have multiple modes, which you can select from a pop-up menu when you click the tool.

Editing Regions

The Edit tools in Pro Tools are used to edit re­gions in the Edit window. A region is a piece of audio or MIDI data that can also have associated automation data. For example, a region could be a loop, a guitar riff, a verse of a song, a sound ef­fect, a piece of dialog, or an entire sound file. In Pro Tools, regions are created from audio or MIDI files, and can be arranged in audio and MIDI track playlists.

4 Click at the beginning of the region and drag
right to shorten the region.
5 Move the cursor near the end of the audio re-
gion (notice the cursor changes to a “]”).
Trimming the end of a region
6 Click at the end of the region and drag left to
shorten the region.
Trimming Regions
After recording an audio track, you will have an audio region on that track. If there is some si­lence at the beginning of the region, or there is some extra audio at the end of the region, you can use the Trimmer tool in Slip mode to shorten the beginning or end of the region.

To trim an audio region:
1 Select Slip mode.
2 Select the Trimmer tool.
3 Move the cursor near the beginning of the au-
dio region (notice the cursor changes to a “[”).

You can also extend a region using the Trimmer tool if there is audio data beyond the current boundaries of a region. If extending the region’s beginning, drag to the left; if extending the re­gion’s end, drag to the right.
Arranging Regions
There are many ways to edit and arrange re­gions; the following example demonstrates how you might create and arrange a drum loop to compose a rhythm track.
To create and arrange a rhythm sequence:
1 Open or create a session in Pro Tools.
2 Specify the session meter (MIDI > Change
Meter) and tempo (MIDI > Change Tempo).
3 Select Grid mode.
4 Prepare to record using a MIDI click (see “Us-
ing the Click” on page 73).
Trimming the beginning of a region
Chapter 5: Working with Pro Tools 89
5 Record a drum track (see “Recording an Audio
Track” on page 84) keeping in mind that you want to use only the best bar (measure). Your re­cording should fit the grid at the specified tempo and meter.
– or –
Import an existing audio file, such as a drum loop from a sample library, and place it on an audio track (see “Importing Audio” on page 81).
6 Drag on the waveform with the Selector to
make a one-bar selection. Note that the selec­tion snaps to the specified grid.
Making a selection in Grid mode
7 Create a new audio track (File > New Track).
8 From the Grabber pop-up menu, select the
Separation Grabber tool.
9 With the Separation Grabber tool, drag the se-
lection to the beginning of the new audio track. A new region is created and appears at the be­ginning of the new track.
11 In the Repeat dialog, enter a number of re-
peats, and click OK.
You now have a new rhythm track with a “looped” (repeated) phrase. You can use these editing tools to do much more advanced and in­volved editing of regions. For example, you could separate beats or “hits” into individual re­gions and rearrange them in Grid or Shuffle mode as a way of coming up with new and in­teresting rhythms.

Playlists and Non-Destructive Editing

Playlists let you create and retrieve multiple ver­sions of track edits. A playlist can be a complete take, an overdub, or an arrangement of selec­tions from multiple takes. You can duplicate playlists to save edits in their current state, then continue making additional edits to the new playlist knowing you can always go back to the previous version.
To create multiple playlists for editing:
1 Start with a track on which you want to try
different edits.
2 From the Playlist Selector pop-up menu,
choose Duplicate.

4 Make your first series of edits.
5 Return to the original playlist by selecting it
from the Playlist Selector pop-up menu.
6 Repeat steps 2–5 for any further edits.

Basic Signal Routing

In this way, you can try out different edits of a track, and switch back and forth between playl­ists for comparison.

Mixing

The Pro Tools mix environment provides many familiar channel strip controls for setting vol­ume, pan, solo, and mute. Mixer and I/O con­trols can be shown in both the Mix and Edit windows.
To view the Mix window:
Select Windows > Show Mix.
Press Command+Equals (=) on Macintosh, or Control+Equals (=) in Windows to switch between the Edit and Mix windows.
Using Channel Strip Controls
Volume Increase or decrease the track level by
dragging its Volume fader up or down.
Pan Pan a track left or right in the mix by drag­ging its Pan slider left or right.
Solo Solo a track (muting all other tracks) by clicking its Solo button.
Signal routing is accomplished by assigning track inputs and outputs. Audio track inputs can be from any hardware input or bus path. Once recorded, an audio track’s input is its audio file on disk. Auxiliary Inputs can be any hardware input or internal bus path. For all types of audio tracks, outputs can be routed to any hardware output or internal bus path.
Together, these signal routing features let you set up virtually any mixer architecture for your projects, including submixing, sends and re­turns for effects processing, and multichannel mixing for surround.
Send and Return Submixing for Effects Processing
When you are submixing for reverb, delay, and similar effects processing, you can use sends and Auxiliary Inputs to achieve traditional send/re­turn bussing. You can use a real-time plug-in (see “Plug-Ins” on page 94) or a hardware I/O in­sert (see “Connecting Effects Units” on page 69) as a shared resource for all tracks included in a submix. The wet/dry balance in the mix can be controlled using the track faders (dry level) and Auxiliary Input fader (wet, or effect return level).
Mute Mute a track by clicking its Mute button.
Chapter 5: Working with Pro Tools 91
Creating a Send
Creating a Return
Pro Tools provides up to five sends per audio track. A send can be mono or stereo, routing to an output or one of 64 internal bus paths.
To assign a send on a track:
1 Make sure Sends View is enabled in the Mix
window (Display > Mix Window Shows > Sends View).
2 Click the Sends button on an audio track and
choose a bus path from the pop-up menu.
Assigning a send to a stereo bus path
3 Set the output level of the send. You can set
the send level to zero by Option-clicking (Mac­intosh) or Alt-clicking (Windows) the send fader.
You can configure the default level for new sends to be
or at unity gain (0 dB) by en-
abling or disabling the Sends Default To “–INF” option under the Operation Prefer­ences.
Auxiliary Inputs can be created to act as return channels for busses, as well as for inputs from hardware sources.

To create a return:
1 Choose File > New Track and specify 1 mono
or stereo Auxiliary Input, then click Create.
2 Click the Input Selector of the Auxiliary Input
and set it to the bus path you assigned to the sends on the source tracks.
3 Click the Output Selector of the Auxiliary In-
put and choose an output path.
Getting Started with HD92

Master Faders

Master Faders are used as output and bus mas­ters, and can control any mono, stereo or multi­channel output or bus path in a session. You can then use the controls on the Master Fader to control the volume, solo and mute, or apply in­serts to those paths.
To create a Master Fader:
1 Choose File > New Track and specify 1 mono
or stereo Master Fader track, then click Create.
2 In the Mix window, click the Master Fader’s
Output Selector and choose the output path that you want to control. You can choose either outputs or internal busses.
When you are mastering your final mix, it is rec­ommended that you use a dither plug-in on the Master Fader controlling your main outputs (see “Using Dither on Mixdown” on page 96).

To use a Master Fader as a master stereo volume control for all tracks in a session:
1 Choose File > New Track and specify 1 stereo
Master Fader track, then click Create.
2 Set the outputs of all audio tracks in the ses-
sion to outputs 1–2 and set the panning of each track.
3 Set the output of the Master Fader to your
main output path (outputs 1–2).
Chapter 5: Working with Pro Tools 93

Plug-Ins

Plug-ins provide EQ, dynamics, delays and many other types of effects processing.
Plug-ins function either in real time or in non­real time. TDM and RTAS plug-ins are non-de­structive effects, which are inserted on tracks to process audio in real time—just like an external hardware processor (during playback). Audio­Suite plug-ins, on the other hand, are destruc­tive effects that process audio files on disk in non-real time.
Real-time plug-ins are assigned to tracks from the Inserts view in the Mix or Edit windows. Once assigned to a track, plug-ins appear in the track’s Inserts view, and can be opened by click­ing on the Insert button.
Plug-InInsert button
Pro Tools comes with a complete set of DigiRack plug-ins, and many more are available from Digidesign and our Development Partners.
For more information about plug-ins, see the DigiRack Plug-Ins Guide, the Digide­sign Plug-Ins Guide, and the Plug-Ins chap­ter of the Pro Tools Reference Guide.

Mix Automation

Mix automation lets you record, or automate, changes to track and send levels, mutes, pan, and plug-in parameters. MIDI tracks provide volume, pan, and mute automation only.
To write automation:
1 In the Automation Enable window
(Windows > Show Automation Enable), enable an automation type (volume, pan, mute, send level, send pan, send mute, or any plug-in auto­mation).
2 Select an automation mode for the tracks to be
automated (Write, Touch, Latch, or Trim mode).
Compressor plug-in
To insert a real-time plug-in on a track:
1 Make sure the Inserts View is shown in the
Mix or Edit window.
2 Click the Insert Selector on the track and se-
lect the plug-in that you want to use.
