Logic Pro is a digital audio workstation and Musical Instrument Digital Interface MIDI sequencer software application for the Mac OS X platform. It was originally created in the early 1990s as Notator Logic, or Logic, by German software developer C-Lab, later Emagic. It became an Apple product, eventually known as Logic Pro, after Apple bought Emagic in 2002.
A consumer-level version based on the same interface and audio engine but with reduced features, called Logic Express, was 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. On December 8, 2011, the boxed version of Logic Pro was discontinued, along with Logic Express, and Logic Pro is now only available through the Apple App Store at the price of $199 in the United States, which used to be the price of Logic Express.
Logic Pro provides software instruments, audio effects and recording facilities for music synthesis. It also supports Apple Loops – royalty-free professionally recorded instrument loops. Logic Pro and Express share many functions 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). 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.
The software instruments included in Logic Pro X include:Drum Kit Designer, Drum Machine Designer, ES, ES2, EFM1, ES E, ES M, ES P, EVOC 20 PolySynth, EXS24 mkII, Klopfgeist, Retro Synth, Sculpture, Ultrabeat, Vintage B3, Vintage Clav, Vintage Electric Piano. These instruments produce sound in various ways, through subtractive synthesis (ES, ES2, ES E, ES M, ES P, Retro Synth), frequency modulation synthesis (EFM1), wavetable synthesis (ES2, Retro Synth), vocoding (EVOC 20 PolySynth), sampling (EXS24 mikII, Drum Kit Designer), and component modeling techniques (Ultrabeat, Vintage B3, Vintage Clav, and Vintage Electric Piano, Sculpture). As of version 10.2, Logic Pro X also includes Alchemy, a sample-manipulation synthesizer that was previously developed by Camel Audio. The software instruments are activated by MIDI information that can be inputed via a midi instrument or drawn into the midi editor.
Audio effects include amp and guitar pedal emulators, delay effects, distortion effects, dynamics processors, equalization filters, filter effects, imaging processors, metering tools, modulation effects, pitch effects, and reverb effects. Among Logic's reverb plugins is Space Designer, which uses convolution reverb to simulate the acoustics of audio played in different environments, such as rooms of varying size, or emulate the echoes that might be heard on high mountains.
The application features distributed processing abilities (in 32-bit mode), 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. As of version 10.0.7, Logic can access 24 processing threads, which is inline with Apple's flagship 12-core Mac Pro.
Creator and notator
In the mid-to-late 1980s, Gerhard Lengeling and Chris Adam developed a MIDI sequencer program for the Atari ST platform called Creator. When musical notation capabilities were added, this became Notator, and later Notator SL. For simplicity these three are collectively referred to as Notator.
Its main rivals at the time included Performer, Vision & Steinberg 16. Most MIDI sequencers presented a song as a linear set of tracks; however, Notator and Vision were pattern-based sequencers: songs were built by recording patterns (which might represent for example Intro, Verse, Chorus, Middle-8, Outro) with up to 16 tracks each, then assembling an Arrangement of these patterns, with up to 4 patterns playing simultaneously at any one time in the song. This more closely resembled working principles of hardware sequencers of the 1970s and 1980s.
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 afterward the popularity of Steinberg's Cubase 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 new program, Notator Logic, which attempted to fuse both track- and pattern-based operation (but looked much more like track-based sequencers than Notator). While rich in features, early versions of Logic on the Atari lacked the intuitiveness and immediacy of either Cubase or Notator, and never achieved the same success. However, by this time the Atari was becoming obsolete, and part of the reason why Notator Logic had been written from scratch with an object oriented GUI (though it shared the same nomenclature as its predecessor) was to make it easier to port to other platforms. The Notator preface was dropped from the product name and the software became known as simply Logic.
As later versions of the software became available for Mac OS and Windows platforms, and acquired ever more sophisticated functions (especially in audio processing) to take advantage of increased computing power, Logic, together with the rise of the PC, gained popularity again.
Apple acquired Emagic in July 2002. The announcement included the news that development of the Windows version would no longer continue. This announcement caused controversy in the recording industry with an estimated 70,000 users having invested in the Windows route not wishing to reinvest in a complete new system. It is unknown how many users may have abandoned Logic upon its acquisition by Apple.
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. Logic 5.5.1 was the last version to be released for Windows. From Logic 6 onwards, the software would only be available on Mac OS.
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.
In March 2004 Apple released Logic Pro 6, which consolidated 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 Pro 7
Logic Pro 7 was released September 29, 2004. Most notably, Apple modified the interface of Logic 7 to look more like a product that was developed by Apple.
Additions to Logic Pro 7 included: the integration of Apple Loops, Distributed Audio Processing (a 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 Pro 8
On September 12, 2007, Apple released the Logic Studio suite that included Logic Pro 8. Logic Pro was no longer a separate product, although a limited version Logic Express 8 was released on the same day, and 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 of 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.
Logic Pro 9
On July 23, 2009, Logic Pro 9 was announced. A major new feature included "Flex Time", Apple's take on "elastic" audio, which allows audio to be quantized. 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 not officially supported for use on PowerPC computers. SoundDiver, which had been quietly bundled with previous versions, was dropped, eliminating support for arguably the world's most popular synthesizer editor/librarian. As Apple has bundled so many software instruments with Logic, it is not likely that we'll see the return of integration with external synthesizer hardware to the Logic platform.
On January 12, 2010, Apple released Logic Pro 9.1, an Intel only release, thereby officially discontinuing Logic for the PowerPC platform. Logic Pro 9.1 has the option of running in 64 bit mode, which allows the application to address more memory than in the past. Says Apple "With 64-bit mode, the application memory is not limited to 4GB as with 32-bit applications, so there is essentially no practical limit by today's standards." Third party plug-ins that are 32 bit are still compatible, but will run from a 'wrapper' inside Logic Pro itself.
On December 9, 2011, Apple announced that Logic Pro Studio 9 would no longer be available on DVD, and would only be sold via the Mac App Store. The price was reduced from $499 to $199.99 for the Logic Pro app, and $29.99 for MainStage. The download was just over 400MB, and 19GB of optional loops were available as in-app downloads.
This version of Logic Pro Studio 9 no longer allows users to access any microtunings in scala format other than those provided with the software by Apple.
Logic Pro X
Released as successor to Logic Pro 9 on July 16, 2013, Logic Pro X (10.0.0) included a new, single-window customizable interface, with a design in line with Final Cut Pro X, as well as new features. New tools in this release are Drummer, a virtual session player that automatically plays along with your song in a wide variety of drumming styles and techniques, and Flex Pitch, a Flex Time equivalent for pitch editing in audio recordings. Also, a new "Smart Controls" feature allows users to map parameters from an array of plugins to a single, convenient control interface. Redesigned keyboards and synths were included, together with new stomp boxes, bass amp and drum kit designers, and a chord arpeggiator. A completely rebuilt sound and loop library was introduced, along with a new Patch architecture. Logic Pro X has also improved track organization by allowing users to group multiple tracks into 'folder' like categories (e.g., acoustics, synthesizers, vocals, percussion, etc.). In addition to this organization, Logic Pro X allows individuals to trigger 'solo,' 'mute,' and 'volume' controls for each group. Further improvements were made to score editing, exporting (now compatible with MusicXML format), and introduces MIDI plug-in compatibility. Coinciding with the release of Logic Pro X was the release of a companion iPad app called Logic Remote, which allows wireless control of Logic Pro X, including Touch Instruments for playing and recording software instruments as well as tools for navigating, making basic edits and mixing.
Since this release, Logic Pro X runs in 64-bit mode only and no longer works with 32-bit plug-ins. Logic Pro X is capable of transferring most data from previous projects saved in Logic Pro 5 and later, though the transfer to 64-bit only means older 32-bit plugins will no longer work.
