Logic Pro 是一款Mac平台的数字音频工作站于MIDI音序器软件。Logic Pro最早由德国软件开发商Emagic开发，并随着2002年苹果公司对Emagic的收购成为苹果的产品，并作为苹果的专业级音乐软件套装Logic Studio的一部分。

另一款消费级的音频软件Logic Express由Logic Pro缩减而来，与Logic Pro有想同的音频处理引擎和交互界面。作为随售出的Mac附赠的软件、iLife套件的一部分，苹果的另一款名为GarageBand的软件也是采用了相同的音频处理引擎。2011年12月8日，苹果不再提供盒装版的Logic Pro和Logic Express软件，Logic Pro只能从App Store购买，价格位199美元，与先前的Logic Express价格相同。

特性

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

Logic Pro提供软件乐器、合成器、音效和录音工具，还支持Apple Loops（在全球范围内免权利金的、专业录制的乐器乐句循环）。音效包括失真、Dynamics processors、Equalization Filters和Delays。Space Designer插件可以模拟各种不同的声学环境，例如尺寸变化的房间，或产生在高山里能听到的回声。Logic Pro能够与MIDI键盘和控制器协同工作（输入和输出）。 It features real-time scoring in musical notation, 支持吉他 tablature, 和弦 abbreviations and drum notation.

Logic Pro与Logic Express共用许多功能和同样的界面。Logic Express仅支持2轨道的立体声，而Logic Pro能够处理多轨道的环绕声它们都可以支持最多255个音轨，具体取决于系统性能（CPU与硬盘的速率、寻道时间).

Logic Pro以分布式处理功能为特色（在32位模式下）, which can function across an Ethernet LAN. 一台电脑运行Logic Pro网络中的其他电脑运行Logic node。 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. Logic can access up to 16 processing threads, compared to 24 threads available on Apple's flagship 12-core Mac Pro computer.

历史

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 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 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.

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). 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 degree of success. However, by this time the Atari was becoming obsolete, and part of the reason why it 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 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, in conjunction 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.

版本

早期版本

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 for the Apple Mac system.

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.

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.

Logic Pro 8

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 (a function which almost all competing audio applications had at this point), 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 in physical form, 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.
