Getting Started With Plug-Ins

Digidesign plug-ins provide a comprehensive set of digital signal processing tools for profes­sional audio production.
This guide explains the use of each of the plug­ins currently available from Digidesign.
These plug-ins include:
Bruno™ & Reso™ cross-synthesis plug-ins
D-Fi™ creative sound design plug-ins
DINR™ intelligent noise reduction
Maxim™ peak limiter/sound maximizer
Reverb One
SoundReplacer™ drum and sound replacement
plug-in
SurroundScope

System Requirements

To use Digidesign plug-ins you need:
A Digidesign-qualified Pro Tools system
– or –
A third-party software application that sup­ports the Digidesign TDM, RTAS, or AudioSuite plug-in standard
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 our Web site (www.digidesign.com/compato).
For more information on using plug-ins during mixdown with Pro Tools, see the Pro Tools Reference Guide.
Chapter 1: Getting Started With Plug-Ins
1

Plug-In Formats

Plug-ins are special-purpose software compo­nents that provide additional signal processing functionality to Pro Tools. There are three for­mats of plug-ins:
• TDM plug-ins (real-time, DSP-based)
•RTAS plug-ins (real-time, host-based)
• AudioSuite plug-ins (non-real-time, file-based processing)

TDM Plug-Ins

(TDM Systems Only)

RTAS Plug-Ins

RTAS (Real-Time AudioSuite) plug-ins provide features and functionality similar to their TDM counterparts, but unlike TDM plug-ins, they rely on and are limited by the processing power of your computer. The more powerful your com­puter, the greater the number and variety of RTAS plug-ins that you can use simultaneously.
Because of this dependence on the CPU or
processing
currently in a session, the greater the impact on other aspects of system performance, such as available track count, edit density, and automa­tion latency.
, the more RTAS plug-ins you use con-
host
TDM (Time Division Multiplexing) plug-ins function as track inserts, are applied to audio during playback, and process audio nondestruc­tively in real time. TDM plug-ins are designed for use on Pro Tools TDM systems, and rely on the processing power of Digidesign DSP cards.
The number and variety of TDM plug-ins that you can use simultaneously in a session are lim­ited only by the amount of DSP available. You can increase available DSP by installing addi­tional HD Accel, HD Process, MIX Farm, or DSP Farm cards in your computer. This power­on-demand aspect is a significant advantage of TDM-based systems.
MIX Farm and DSP Farm cards are not supported on Pro Tools|HD-series systems. HD Accel and HD Process cards are not supported on Pro Tools|24 MIX-series sys­tems.
RTAS plug-ins can be used on both Pro Tools TDM and LE systems.

AudioSuite Plug-Ins

Non-real-time AudioSuite plug-ins are not used during playback, but are instead used to process audio files on disk, creating new, rewritten audio files with the effect permanently applied. Audio­Suite plug-ins can be used on all Pro Tools sys­tems.

Installing Plug-Ins

The Digidesign Plug-In Installer CD-ROM lets you install and use not only the plug-ins which you have purchased, but also a demo version of other Digidesign plug-ins. Demo versions of plug-ins can be used for the length of their demo period, after which they will expire. Once the demo version of a plug-in has expired, pur­chase the plug-in and authorize it, or remove it (see “Removing Expired Plug-Ins” on page 4).
Digidesign Plug-Ins Guide
2

Demo Plug-Ins and Authorization

Some plug-ins require an iLok USB Smart Key present in order to run in demo mode. Demo au­thorization for such plug-ins can only be in­stalled over the internet from Digidesign’s Web site (www.digidesign.com) while you launch Pro Tools. Make sure that your Pro Tools­equipped computer is internet-ready and that your iLok USB Smart Key is inserted in an avail­able USB port before you launch Pro Tools to complete this automated process. This is a one­time-only procedure for plug-ins that require it.

Updating Older Plug-Ins

Because the Plug-In Installer CD-ROM contains the latest versions of all Digidesign plug-ins, you can use it to update any plug-ins you already own by installing the desired plug-in from the CD-ROM. If the installed iLok is already autho­rized, or there is already a valid authorization key on the destination hard disk, you will not be prompted for a new one.
Digidesign plug-ins for Pro Tools 5.3 and lower are not supported in Pro Tools 6.0 and higher.
Installation
To install a plug-in:
1
Insert the Plug-Ins Installer CD-ROM in your
CD-ROM drive.
6 Repeat steps 3 through 5 for additional plug-
ins that you want to install.
You will be prompted to authorize the plug-ins when you launch Pro Tools.

Digidesign Registration

Make sure to complete and return the registra­tion card included with your Digidesign plug-in. Registered users will receive periodic software update and upgrade notices. Please refer to the registration card for information on technical support.

Authorizing Plug-Ins

Digidesign plug-ins are authorized using the iLok USB Smart Key from PACE Anti-Piracy. The iLok is similar to a dongle, but unlike a dongle, it is designed to securely authorize multiple soft­ware applications from a variety of software de­velopers.
One iLok USB Smart Key is included with Pro Tools|HD core systems. This key can hold over 100 authorizations for all your iLok-en­abled software. Once a software authorization is added to an iLok USB Smart Key, you can use the iLok to authorize that software on any com­puter. (For more information, see the iLok Usage Guide.)
2 Open the Digidesign Plug-Ins directory.
3 Locate and double-click the Install file on the
Installer CD-ROM for the plug-in you want to install.
4 Follow the on-screen instructions.
5 When the installation is complete, click Fin-
ish (Windows) or Quit (Macintosh).
Authorizations are added to an iLok using Li­cense Cards that have a small punch-out GSM plastic chip. License Cards are specific to each plug-in. You will receive the appropriate License Cards for the plug-ins that you purchase.
Chapter 1: Getting Started With Plug-Ins
3
To add an authorization to an iLok:
1 Insert the iLok into an available USB port on
your computer.
2 Launch Pro Tools. You will be prompted to au-
thorize any installed unauthorized plug-ins.
If you are already using a demo version of the plug-in, launch Pro Tools before you in­sert the iLok, then insert the iLok into any available USB port when prompted by Pro Tools.
3 Follow the on-screen instructions until you
are prompted to insert the License Card into the iLok.
4 Separate the License Card—the smaller GSM
cutout—from the larger protective card by pull­ing the cutout up and out with your thumb.
5 Insert the License Card into the iLok. Visually
verify that the License Card makes contact with the iLok’s metal card reader.

Removing Expired Plug-Ins

If you let a demo version of a plug-in expire, you should remove it from your system. Otherwise, each time you open Pro Tools you will be prompted with a message that the plug-in has expired.

Windows

To remove an expired plug-in:
1 From the Start menu, choose Settings > Con-
trol Panel and double-click Add or Remove Pro­grams.
2 Select the expired plug-in from the list of in-
stalled applications and click the Change/Re­move button.
3 When removal is complete, click OK to close
the window.

Mac OS X

To remove an expired plug-in:
1 Locate the Library/Application Sup-
port/Digidesign folder on your Startup drive.
iLok with License Card
6 Follow the on-screen instructions to complete
the authorization process.
7 After authorization is complete, remove the
License Card from the iLok. (If you have to re­move the iLok to remove the License Card, be sure to re-insert the iLok in any available USB port on your computer.)
Digidesign Plug-Ins Guide4
2 Open the Plug-Ins folder or Plug-Ins (Unused)
folder and drag the expired plug-in to the Trash.
3 Empty the Trash.

Mac OS 9

To remove an expired plug-in:
1 Open the DAE folder inside your System
Folder.
2 Open the Plug-Ins folder or Plug-Ins (Unused)
folder and drag the expired plug-in to the Trash.
3 Empty the Trash.

Allocating Additional Memory to Pro Tools

(Mac OS 9 Only)
If you plan to use a large number of TDM plug­ins in addition to the DigiRack TDM plug-ins in­cluded with Pro Tools, allocating additional memory to Pro Tools will help ensure reliable system performance.
If enough RAM is available in your computer, al­locate 1–2 megabytes of additional RAM to Pro Tools for each non-DigiRack plug-in in­stalled on your system.
To allocate additional memor y to Pro Tools:
1 Start Pro Tools so that it can calculate its basic
memory allocation.
2 Go to the Finder and choose About This Com-
puter from the Apple menu.
8 Close the Get Info dialog.
The next time you start Pro Tools, it will use this new memory allocation.

Working with Real-Time Plug-Ins

Real-time plug-ins process audio nondestruc­tively in real time. They do not alter the original source audio, but only apply their effect during playback.

Processing Power Requirements of TDM and RTAS Plug-Ins

There are two formats of real-time plug-ins:
TDM Plug-Ins Rely on the processing power of Digidesign DSP cards. TDM plug-ins run only on TDM-equipped Pro Tools systems.
RTAS Plug-Ins Rely on the processing power of your computer. RTAS plug-ins run on Pro Tools TDM and LE systems.
TDM and RTAS plug-ins differ in their process­ing power requirements.

TDM Plug-Ins

Each real-time TDM plug-in that is inserted in a Pro Tools session uses a portion of your system’s total available DSP resources. Since these DSP re­sources reside on the cards that make up your particular Pro Tools hardware configuration, the amount of DSP available depends entirely on the number and type of DSP cards in your system.
You can add more mixing and processing power to your system by installing additional DSP cards, provided you have unused PCI expansion slots in your computer or use a Digidesign-ap­proved Expansion Chassis.
Chapter 2: Working with Real-Time Plug-Ins 7
The System Usage window (Windows > Show System Usage) shows how much DSP is available on your system and approximately how it is cur­rently being used.
For more information on the System Usage window, see the
System Usage window
Pro Tools Reference Guide.
See Appendix A, “DSP Requirements for TDM Plug-Ins” for the number of instances of each Digidesign TDM plug-in that can be powered by a single DSP chip. DSP usage differs according to card type.
DSP Sharing Between TDM Plug-Ins
With Digidesign’s MultiShell II technology, dif­ferent types of TDM plug-ins can share the same DSP chip at the same time. This lets you simul­taneously use a greater variety of plug-ins by ef­ficiently managing the DSP available on each chip in your system.
In order to take advantage of this capability, plug-ins must be MultiShell II compatible.
The following Digidesign plug-ins are Multi­shell:
• Maxim
• D-Fi
• SurroundScope
SoundReplacer is an AudioSuite only plug-in.

RTAS Plug-Ins

RTAS plug-ins rely on and are limited by the pro­cessing power of your computer’s CPU. The more RTAS plug-ins you use concurrently in a session, the greater the impact it will have on other aspects of your system’s performance, such as maximum track count, the density of edits possible, and latency in automation and recording.
The CPU meter in the System Usage window (Windows > Show System Usage) shows how much of your computer’s processing power is currently being used by Pro Tools, and how much is still available.
For more information on the System Usage window, see the
Digidesign Plug-Ins Guide8
Pro Tools Reference Guide.

Improving RTAS Plug-In Performance

You can increase the number of RTAS plug-ins your system can use concurrently by increasing the Hardware Buffer Size and CPU Usage Limit.
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.
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 response 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. (On dual-processor Mac­intosh computers, this setting controls the allo­cation of a single processor.)
2 From the H/W Buffer Size pop-up menu, select
the audio buffer size, in samples.

Delay in Digital Signal Processing

DSP processing in digital audio systems incurs signal delay of varying amounts. Such delays can vary from as short as a few samples to as long as several hundred samples, depending on the type of processing applied.
If you have recorded an instrument on multiple tracks using multiple microphones (a drum kit for example) and process the different tracks with different plug-ins, the tracks may go out of phase. You will then need to compensate for these delays to avoid phase correlation prob­lems.
See Appendix B, “DSP Delays Incurred by TDM Plug-Ins” for information on delays inherent in specific Digidesign TDM plug­ins. See the guide to calculating DSP-induced delays.
Pro Tools Reference Guide for a

Plug-Ins as Inserts

Real-time plug-ins are available as in-line inserts on audio tracks, Auxiliary Inputs, and Master Faders. A maximum of 5 real-time plug-ins can be used per track.
When more than one insert is used on a track, they process the audio in series, each effect be­ing added to the previous one, from top to bot­tom in the Mix window.
If you are using both TDM and RTAS plug­ins on the same track, RTAS plug-ins must occur first in the signal chain, followed by TDM plug-ins. You cannot place TDM plug-ins before RTAS plug-ins.
Inserts can be used in two ways:
On Single Tracks An insert can be applied to an individual audio track or Auxiliary Input using the Insert Selector on that track.

Compensating for Delay with TimeAdjuster

(TDM Systems Only)
You can compensate for TDM plug-in-induced delays by using the TimeAdjuster plug-in. This plug-in lets you apply a specific number of sam­ples of delay to the signal path of a Pro Tools track. TimeAdjuster provides settings files that apply the correct compensation time in samples for delay introduced by one or more plug-ins. See the DigiRack Guide for information about the Time Adjuster plug-in.
Digidesign Plug-Ins Guide10
With in-line inserts, you control the level of ef­fect by adjusting the controls of the plug-in.
As Shared Resources An insert can be used as a shared resource in a send-and-return arrange­ment by bussing signals from several tracks to an Auxiliary Input, and applying the insert to the Auxiliary Input track. With such an arrange­ment, you can control the send level for each track and the overall level of the effect can be controlled from the Auxiliary Input track.
Shared arrangements let you make more effi­cient use of your system’s processing power.
On TDM systems, RTAS plug-ins can be in­serted on audio tracks only. For Auxiliary Inputs or Master Faders, use TDM plug-ins.

Pre-Fader Operation

Real-time plug-ins function as pre-fader inserts (except on Master Fader tracks, where inserts are post-fader), meaning that their input levels are not affected by a track’s volume fader.
Real-time plug-ins are pre-fader, but post-disk. This means that if you record to disk with a plug-in inserted on the record track, you will hear the effect of the plug-in, but the effect will not be recorded to disk.
To record with a plug-in effect, create an Auxil­iary Input, insert the desired effect on the Aux­iliary Input track, then route the Auxiliary Input to the audio track to which you want to record. Alternatively, bounce the audio track with the plug-in after recording in order to write the ef­fected audio to disk.

Mono, Multi-Mono, and Multichannel Plug-Ins

Plug-ins can be used in mono, multi-mono, or multichannel formats, depending on the type of plug-in and whether the destination is a mono or multichannel track.
Mono Plug-Ins Used on mono tracks. Some mono plug-ins let you generate a stereo output from a mono channel. Plug-ins that occur on a track after a stereo plug-in are used in stereo as well.
Multi-Mono Plug-Ins Used on stereo or greater­than-stereo multichannel tracks when a multi­channel version of the plug-in is not available. Multi-mono plug-ins will analyze and process each channel independently without regard to each other. Controls for all channels are linked by default so that you can adjust them in tan­dem. You can unlink controls for independent adjustment using the Master Link button. See “Linking and Unlinking Controls on Multi­Mono Plug-ins” on page 16.
Multi-mono plug-ins, such as dynamics­based or reverb plug-ins, may not function as you expect. Use the multichannel version of a multi-mono plug-in when available.
Multichannel Plug-Ins Used on stereo and greater-than-stereo multichannel tracks. On greater-than-stereo multichannel tracks, the controls for all channels are always linked to­gether.
In general, when working with stereo and greater-than-stereo tracks, use multichannel plug-ins. If a multichannel version of a plug-in is not available, use a multi-mono version.

Using a Key Input for Side­Chain Processing
Some plug-ins feature side-chain processing ca­pabilities. With side-chain processing you can trigger a plug-in from a separate reference track or external audio source. The source used for triggering is referred to as the Key Input. Key in­puts are monophonic.
A typical use for this feature is to control the dy­namics of one audio signal using the dynamics of another signal (the Key Input). For example, a kick drum track could be used to trigger gating of a bass track to tighten it up, or a rhythm gui­tar track could be used to gate a keyboard pad.
RTAS plug-ins do not provide side-chain processing when used on TDM-based sys­tems. If you want to use side-chain process­ing, use the TDM versions of plug-ins on TDM-based systems.

Key Input Filters

Some plug-ins feature key high-pass and low­pass filters. These controls let you define a spe­cific frequency range in the Key Input signal with which to trigger the plug-in effect. A com­mon production technique is to use these con­trols to filter a drum track so that only specific high frequencies (a hi-hat, for example) or low frequencies (a tom or a kick, for example) trigger the effect.
To use a Key Input for side-chain processing:
1 From the Key Input menu, choose the input
or bus carrying the audio you want to use to trig­ger the plug-in.
Choosing a Key Input
2 Click External Key to activate side-chain pro-
cessing.
3 To hear the audio source you have selected to
control side-chain input, click Key Listen.
4 To filter the Key Input so that only specific fre-
quencies trigger the plug-in, use the Key HPF and Key LPF controls (if available) to select the frequency range.
5 Begin playback. The plug-in uses the input or
bus that you chose as a Key Input to trigger its effect.
6 Adjust the plug-in’s Threshold control (if
available) to fine-tune Key Input triggering.
7 Adjust other controls to achieve the desired ef-
fect.
Digidesign Plug-Ins Guide18

Automating Plug-Ins

You can automate changes to plug-in controls. Because Pro Tools creates a separate playlist for each plug-in control that you automate, you can later edit and modify each automated control individually. This lets you build up complex au­tomation in stages.
To create automation for a stereo plug-in with separate controls for each channel, record the automation for one channel then copy and paste it to the other channel.
To enable plug-in controls for automation:
1 Open the Plug-In window for the plug-in you
want to automate.
2 Click the Automation button in the Plug-In
window.
