Overview
Fundamentally, Pro Tools, like all Digital Audio Workstation software, is similar to a multi-track tape recorder and mixer, with additional features that can only be performed in the digital domain. The high-end version supports sample rates of up to 192 kHz and bit depths of 16 and 24 bit, opens WAV, AIFF, mp3, SDII audio files and QuickTime video files. It features time code, tempo maps, automation and surround sound capabilities. Order of products from lowest to highest are as follows: Essential, M-Powered, LE, HD, HD2 & HD3.[edit] History
Pro Tools was developed by UC Berkeley graduates Peter Gotcher and Evan Brooks. Both were double majors in electrical engineering and computer science at Berkeley. The first incarnation of Pro Tools started life in 1984 as Sound Designer, while the pair were creating and selling drum sound chips under their Digidrums label. Sound Designer was originally designed to edit sounds for the E-MU Emulator sampling keyboard[1]. Gotcher and Brooks discussed with E-MU Systems the possibility of integrating their renamed 'Sound Tools' software into the Emulator III keyboard released in 1987. E-MU rejected this offer and Gotcher and Brooks started Digidesign.[2]Sound Tools[3] was debuted on January 20, 1989 at NAMM (National Association of Music Merchandisers). At this stage Sound Tools was a simple computer based stereo audio editor. Although the software had the possibility to do far more it was limited by the hard drive technology, which was used to stream the audio and allow for the non-destructive editing that Sound Tools offered.[4]
The first version of Pro Tools was launched in 1991, offering 4 tracks and selling for $6000USD. Digidesign continued to improve Pro Tools, adding a sequencer and more tracks, with the system offering recording at 16bit 44.1 kHz. In 1997 Pro Tools reached 24bit, 48 track versions. It was at this point that the migration from more conventional studio technology to the Pro Tools platform took place within the industry.[5]
[edit] Pro Tools in Popular Culture
Ricky Martin’s "Livin’ La Vida Loca" was the first No. 1 single to be recorded, edited, and mixed completely within the Pro Tools environment by Charles Dye and Desmond Child.[6][7] Garbage's Version 2.0 was the first album to be nominated with Grammy for Album of the Year that had been entirely recorded and edited through Pro Tools.Miami is widely believed to be the first city to broadly adopt Pro Tools in professional recording studios, and is often referred to as the 'Ground Zero' for Pro Tools.[8]
Pro tools was used in the creation of the live stadium version of the Believe sound track of Sea World's Believe Shamu Show and was mixed live on Pro Tools inside Shamu Stadium.
Bob Clearmountain once expressed concern that people would acquire Pro Tools system with little understanding of the editing process.[9]
Some artists are now making a point of recording without Pro Tools. [10] Jack White of The White Stripes argues that "Pro Tools is highly inappropriate to record music... It's too easy to correct mistakes, it's too easy to fix things. We hear this sort of clean, plastic perfection that's been applied to all the tracks. That is not the kind of music we grew up loving and listening to and wanting to be a part of."[11]
The rapper GZA named his 2008 album after the program.
Pro Tools was used for creating the audio for the game DJ Hero and Guitar Hero, using the modelling plug-in Eleven for the guitar sounds.[12]
[edit] Interface
Most of Pro Tools' basic functions can be controlled within Edit or Mix windows. The Edit window displays audio and MIDI tracks, and provides graphical representation of the information recorded or imported. Here, audio can be edited in a non-linear, non-destructive fashion. MIDI information can also be manipulated. The Mix window displays each track's fader channel and allows for the adjustment of a channel's volume and pan, as well as being the usual place to insert plug-in effects and route audio to and from different outputs and inputs.The creation of Pro Tools 8 has now seen the addition of a MIDI edit window which enables the user to manipulate MIDI data in either piano-roll or score windows. It also includes the addition of MIDI edit lanes so that the user can see both note, velocity and other CC data in the same window. This move would take Pro Tools from the long held 2 edit window approach to now having 3 edit windows.
Effects processing and virtual instruments in Pro Tools are achieved through the use of plug-ins, which are either processed by the DSP chips as TDM plug-ins, or the host computer as RTAS (Real Time AudioSuite) plug-ins.
[edit] Systems
[edit] Pro Tools HD systems
When run from a host Apple Mac or Windows PC, HD systems perform most audio processing on DSP cards, and use external, rack mountable interfaces to handle incoming and outgoing audio. TDM, a proprietary interconnect based on time-division multiplexing, is used for communication between the devices.Pro Tools systems have long relied on dedicated DSP cards to handle most audio processing, due to the fact that at the time Pro Tools was first developed, consumer-level computers were not powerful enough to process high-end digital audio.[13] A HD Core PCI card or an Accel Core PCIe card is required in a HD 1 system; the inclusion of one or two additional Accel cards upgrades the system to HD 2 or 3 respectively, and increases the system's overall processing power, allowing for higher track counts and more plug-ins. An 'Expansion HD' product increases capability up to a total of 7 cards using Digidesign's PCI-X expansion chassis product, which is available with both PCI-X and PCIe host cards for the computer.
When Pro Tools HD was launched, HD Process cards were available, but owing to supply problems from DSP manufacturers Motorola[citation needed], the line was redesigned and rebranded HD Accel, which offers faster DSP chips and additional RAM. All cards contain 9 DSP chips. When Apple changed the expansion slot architecture of the G5 to PCI Express, Digidesign launched a line of PCIe HD Accel cards. The PCIe HD Core is now an 'Accel Core', whereas the original PCI-X Core remains 'non-Accel'. There are TDM plugins that require the presence of Accel chips to run and therefore cannot run on the earlier non-Accel HD systems.
[edit] Pro Tools LE systems
Consumer-level Pro Tools LE systems perform almost all data processing on the host CPU, with the exception of the Eleven Rack, introduced in September 2009, which includes on-board DSP via dual TMS320c6727b chips. A Digidesign audio card (bundled with the software) must be used for all audio I/O (recording and playback); Pro Tools LE will not run on a normal consumer-grade sound card. The hardware thus doubles as a copy-protection mechanism for the software, as the software will not function without the specialized Digidesign sound card.There are three families of external interfaces for Pro Tools LE systems. The original MBox (2002) and current MBox 2 family connects to, and is powered by a host computer through USB (except the FireWire connected MBox 2 Pro). All have a stereo audio output, and all but the MBox 2 Micro have two line inputs and at least one microphone pre amp. The Digi002 and, currently, Digi003 family is a series of FireWire connected interfaces with larger I/O capabilities, additional methods of inputing audio and four microphone pre amps. The Eleven Rack guitar processor combines in-box DSP processing that offloads the Eleven guitar amp/speaker emulation and guitar effects plug-in running from the host PC and allows those plugins to run standalone. Eleven Rack is Digidesign's first USB2.0 based product and also includes microphone and line-level I/O.
The Pro Tools LE software is essentially a limited version of the HD counterpart, with a smaller track count, no Automatic Delay Compensation (ADC), and lower maximum sampling rate. As no additional DSP cards (with the exception of the on-board DSPs in the Eleven Rack) are required or supported, only RTAS plug-ins can be used. There is a VST to RTAS adaptation software utility made by FXpansion[1]
that will allow VST plugins to be used as RTAS plugins. Time code based grid, import of OMF and AAF files and DigiBase Pro are not available in Pro Tools LE without the purchase of the DV Toolkit or Complete Toolkit software addons.
Also, Multitrack beat detective is not available without music production toolkit.
There are other options there are not available on ProTools LE series like capture or replace regions automatically.

[edit] Pro Tools M-Powered systems
M-Audio, formerly Midiman, was acquired by Avid Technology in 2004–2005, and in April 2005, Digidesign released Pro Tools M-Powered which brought almost all Pro Tools LE functionality to a subset of M-Audio USB, Firewire and PCI interfaces. M-Powered requires M-Audio hardware as an interface and an iLok licence to use Pro Tools M Powered. Mackie Onyx-i Series FireWire Recording Mixers are qualified by Mackie for use with Pro Tools M-Powered 8 on both OS, Mac and Windows.[edit] Pro Tools Essential
This is based on the standard version of the software and enables you to record on up to 16 audio tracks. Up to eight virtual instrument tracks can be used simultaneously, and the Structure Essential plug-in (which gives you more than 60 sounds) comes supplied. It comes bundled with 3 different M-Audio interfaces; Pro Tools Vocal Studio, Keystudio and Recording Studio which are bundles of microphone, keyboard or USB MIDI interface respectively. They are aimed at the starter market, and offer very limited scope including no 3rd party plugins & limited usb device support. No competitive upgrade path or discounts are available either, the next step up in the protools chain is the full retail purchase of one of the other versions.[edit] Control surfaces
Digidesign control surfaces attempt to bridge the gap between old style analogue desks and modern DAWs by providing physical controls for the Pro Tools software. The latest control surface is the C|24, successor to the Control|24, a 24 fader control surface with 16 built in Focusrite "A" Class Mic Preamps. A fairly new addition to the range is the ICON: Integrated Console Environment, combining a tactile control surface and a Pro Tools|HD Accel system in one unit. VENUE, a similar system, was released for live sound applications. These large control surfaces use an Ethernet connection to the host computer, but for Pro Tools users with smaller needs, the Command|8 is a small eight fader control surface which connects via USB.[edit] Related products and services
An official Pro Tools training curriculum and certification program, which includes a full range of Pro Tools–related courses in music and post production, was introduced by Digidesign in 2002. The curriculum is delivered by a number of schools and universities around the world.The Music Production and DV Toolkits increase the capabilities of non HD Pro Tools systems. Both increase the maximum number of tracks and highest possible sample rate to 96 kHz and include numerous additional plug-ins. The LE only DV Toolkit adds feet and frames and timecode timelines and functionality.
[edit] AIR (Advanced Instrument Research)
In August 2005 Avid acquired the German company Wizoo, developers of software based virtual instruments. They further announced the creation of AIR (Advanced Instrument Research) a strategic development which meant Avid would be developing virtual instruments and plug-ins for use in Pro Tools.[14]This was a move which saw the landmark redevelopment of Pro Tools in Pro Tools 8, which relied heavily on the inclusion of AIR plug-ins to bring it closer to its competitor Logic Pro. This was the first version of Pro Tools to see the inclusion of an entire virtual instrument library to assist those composing music[15] and included:
- Structure FREE, a sample playback instrument.
- Boom, a beat box
- Xpand2, a multi-timbral sound playback module.
- DB33, a Hammond Organ emulator
- Vacuum, a monophonic vintage synth.
- Mini Grand, Piano.
