Logic Pro is a hybrid 32 / 64 bit digital audio workstation and MIDI sequencer software application for the Mac OS X platform. Originally created by German software developer Emagic, Logic Pro became an Apple product when Apple bought Emagic in 2002. Logic Pro is part of Apple's Logic Studio bundle of professional music applications.

A consumer-level version based on the same interface and audio engine but with reduced features, called Logic Express, is also available at a reduced cost. Apple's GarageBand, another application using Logic’s audio engine, is bundled in iLife, a suite of software which comes included on any new Macintosh computer.

History

In the mid-to-late 1980s, Gerhard Lengeling and Chris Adam developed a MIDI sequencer program for the Atari ST platform called Creator (the ST was an early favorite among MIDI users during the mid- and late-80s). When musical notation capabilities were added, this became Notator, and later Notator SL. For simplicity these three are collectively referred to as Notator.

Unlike most software sequencers (including its main rivals at the time Performer, Vision & Cubase), which presented a song as a linear set of tracks, Notator was a pattern-based sequencer: a song was built by recording patterns (which might represent for example Intro, Verse, Chorus, Middle-8, Outro) with up to 16 tracks each, and then assembling an Arrangement of these patterns, with up to 4 patterns playing simultaneously at any one point in the song. This more closely resembled the way that hardware sequencers of the 1970s and 1980s worked.

In its time, Notator was widely regarded (by musicians and the musical press of the time e.g. International Musician) as one of the most powerful and intuitive sequencing and notation programs available on any platform, but subsequently Cubase's popularity increased and track-based sequencing prevailed over pattern-based, resulting in the eventual greater integration and hybridization of the two methods in later versions of both Cubase and Logic.

The C-Lab programmers left that company to form Emagic, and in 1993 released a brand new program, Notator Logic, which attempted to fuse both track- and pattern-based operation (but looked much more similar to track-based sequencers than to Notator). Whilst very powerful, early versions of Logic on the Atari lacked the intuitiveness and immediacy of either Cubase or Notator, and never achieved the same degree of success. However, by this time the Atari was becoming obsolete, and part of the reason why it had been written from scratch was to make it easier to port to other platforms. The Notator brand was dropped and the software became known as simply Logic.

As subsequent versions of the software became available for Mac OS and Windows platforms, and acquired ever more sophisticated functionality (especially in audio processing) to take advantage of increased computing power, Logic gained popularity again.

Audio recording

In the early 1990s, with Logic version 1.7 Emagic added the ability to record and mix audio into the sequencer tracks, along with its existing MIDI capabilities that had continued to be expanded as well. At the time, computers were not fast enough to record audio in "native mode", so additional hardware was needed to make it work, usually in the form of sound cards or DSP cards plugged into the computer's internal bus slots, such as the NuBus slots on Macintosh computers. Among the systems that worked with Logic 3 were Digidesign and Motu audio interfaces.

In the mid 1990s, Emagic released the Logic version 4, and their Audiowerk audio interface, introducing the ability for Logic to record and mix audio without requiring additional hardware, although the track counts and processing possibilities were significantly limited by the speed of the computers of those times, which were very slow relative to current systems.

Further developments

Logic 5 featured significant improvements in user interface, and increased compatibility with more types of computers, operating systems, and a wide range of audio interfaces.

With Logic 6, Emagic added the availability of separately packaged software products that were closely integrated add-ons developed specifically for use with Logic, including software instruments, the EXS sampler and audio processing plug-ins. The Logic 6 package also included the stand-alone program Waveburner, for burning redbook audio CD standard-compliant CDR masters for replication, however, that application was considered a free bonus feature; it was not advertised as part of the package and did not include printed documentation. PDF documentation was included on the installer disc.

Apple’s acquisition

Apple acquired Emagic in July 2002. Shortly thereafter, they released Logic 5, which was the final version to support Windows.

In late 2004, Apple released version 7 of Logic Pro, consolidating over 20 different Emagic products, including all instrument and effect plug-ins, Waveburner Pro (CD Authoring application), and Pro Tools TDM support, into a single product package. Apple also released a scaled down version of Logic called Logic Express, replacing two previous versions that filled that position called Logic Silver and Logic Gold. Apple began promoting Logic Pro as one of its flagship software ‘Pro’ applications for the Macintosh platform. Logic was also used as the basis for a modified application titled GarageBand, included as a part of OS X iLife.

Additions to Logic Pro 7 included: the integration of Apple Loops, Distributed Audio Processing (an innovative technology for combining the power of multiple computers on a network), 3 new instruments including Sculpture (a sound modeling synth) and Ultrabeat (a drum synth and sequencer), and 9 new effect plug-ins including Guitar Amp Pro (guitar amp simulator), and a linear phase corrected version of their 6 channel parametric equalizer. In total, Logic Pro 7 now included 70 effect plug-ins and 34 instrument plug-ins. Pro-Tools TDM compatibility, which had been a feature of Logic since version 3.5, was not supported by Logic 7.2 on Intel-based Mac computers; TDM support returned with the release of Logic 8.

Logic 8 and 9

On September 12, 2007, Apple released the Logic Studio suite that included Logic Pro 8. Logic Pro was no longer a separate product, although Logic Express 8, which was released on the same day, remained a separate product.

Significant changes were made for Logic 8. Logic Pro 8 was now mainly Cocoa code, but still included some Carbon Libraries. Alongside changes such as the new processing plug-in (Delay Designer), Apple included features such as Quick Swipe Comping, similar to Soundtrack Pro 2, and multi-take management.

Apple also made changes to ease of use. These include the discontinuation of the XSKey dongle, and a streamlined interface. Each plug-in used in the channel strip opens in a new window when double-clicked. Many the features found in Logic 7 have been consolidated into one screen. Other additions to the new interface included consolidated arrange windows, dual channel strips, built in browsers (like that in GarageBand) and production templates.

On July 23, 2009, version 9 of the product was announced. A major new feature included "Flex Time", Apple's take on "elastic" audio (a function which almost all competing audio applications had at this point). A version of the pedalboard from GarageBand was included, together with a new virtual guitar amplifier where the modeled components could be combined in different ways. There were also a number of improvements to audio editing, fulfilled user requests such as "bounce in place" and selective track and channel strip import, as well as an expanded content library including one more Jam Pack. Some of the bundled software, including MainStage 2 and Soundtrack Pro 3, was also improved. Logic Pro 9 is Universal Binary, although support for use on PowerPC computers is deprecated.

Logic 9.0 and 9.01 had a major issue regarding 32bit RAM memory limitations (also known as "Logic 9 , "Memory bug from hell") but largely magnified compared to Logic Pro 7 and Logic Studio 8. Users around the world have illustrate the issue on every major forum about music production, seeking for a solution. It is now a historical fact that Apple has promoted 64bit computing since year 2003 with the launch advert of the PowerMac G5 but still on 12/2009 did not offer real-life 64bit audio host applications for the end users. From Spectrasonics website: "...At the moment, the only 64 bit host on the Mac is AULab 2.0.1..." 12/15/09.

On 12 January 2010, Apple released Logic Pro 9.1. The majority of its code is 64-bit, addressing 32-bit limitations. The release included Apogee's UV22HR dithering algorithm.

Features

The Space Designer plugin attempts to emulate the characteristic echo and reverberation of a physical environment, using a technique called convolution.

Logic Pro provides software instruments, synthesizers, audio effects and recording facilities for music synthesis. It also supports Apple Loops – royalty-free professionally-recorded instrument loops. Audio effects include distortions, dynamics processors, equalization filters, and delays. The Space Designer plugin simulates the acoustics of audio played in different environments, such as rooms of varying size, or producing the echoes that might be heard on high mountains. Logic Pro can work with MIDI keyboards and control surfaces for input and processing, and for MIDI output. It features real-time scoring in musical notation, supporting guitar tablature, chord abbreviations and drum notation.

Logic Pro and Express share much functionality and the same interface. Logic Express is limited to two-channel stereo mixdown, while Logic Pro can handle multichannel surround sound. Both can handle up to 255 audio tracks, depending on system performance (CPU and hard disk throughput and seek time).

The application features distributed processing abilities, which can function across an Ethernet LAN. One machine runs the Logic Pro app, while the other machines on the network run the Logic node app. Logic will then offload the effects and synth processing to the other machines on the network. If the network is fast enough (i.e. gigabit Ethernet) this can work in near-real time, depending on buffer settings and CPU loads. This allows users to combine the power of several Macintosh computers to process Logic Pro’s built-in software instruments and plug-ins, and 3rd party processing plug-ins.
