Editing Logic Pro (section)

==Features==
Logic Pro provides software instruments, audio effects and recording facilities for music synthesis. It also supports Apple Loops&nbsp;– [[Royalties|royalty-free]], professionally recorded instrument loops. Logic Pro and Express once shared many functions and the same interface. [[Logic Express]] was limited to two-channel stereo mixdown, while Logic Pro can handle multichannel [[surround sound]]. Logic Express only handled up to 255 audio tracks, depending on system performance ([[CPU]] and [[hard disk]] [[throughput]] and [[seek time]]), while, as of version 10.4.5, Logic Pro can handle up to 1,000.<ref>{{Cite web|date=2019-06-14|title=Logic Pro X 10.4.5 update raises the track count into the thousands|url=https://www.gearnews.com/logic-pro-x-10-4-5-update-raises-the-track-count-into-the-thousands/|access-date=2020-08-29|website=gearnews.com|language=en-GB}}</ref>

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 (music)|chord]] abbreviations and drum notation. Advanced MIDI editing is possible through Logic Pro's MIDI Transform Window,<ref>{{cite web | url=https://www.midi.com.au/logic-pro-x-midi-files/ | title=Edit MIDI Files in Logic Pro X }}</ref> where velocity, pitch, pitch-bends, note length, humanize, and precise note positioning can be edited.<ref>{{cite web |last1=Ialuna |first1=John |title=Author |url=https://www.midi.com.au/logic-pro-x-midi-files/ |website=Hit Trax MIDI Files |publisher=John Ialuna |access-date=2018-08-09 }}</ref>

===Software instruments===
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, Sampler, Quick Sampler, Step Sequencer, 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 (Sampler, Quick Sampler, 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 input via a MIDI instrument or drawn into the MIDI editor.<ref name="The Logic Pros: A look at Logic’s new heavy weight sample manipulation synth Alchemy">{{cite web | url=http://9to5mac.com/2015/08/30/logic-pros-alchemy-update/ | title=The Logic Pros: A look at Logic's new heavy weight sample manipulation synth Alchemy | date=2015-08-30 | access-date=2015-09-01 }}</ref>

===Audio effects===
{{stack|[[Image:Space Designer Logic Effect.png|thumb|250px|The Space Designer plugin attempts to emulate the characteristic echo and [[reverberation]] of a physical environment, using a method called [[Convolution reverb|convolution]].]]}}
Audio effects include amp and guitar pedal emulators, delay effects, distortion effects, [[dynamics (music)|dynamics]] processors, [[Equalization (audio)|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 [[Echo (phenomenon)|echoes]] that might be heard on high mountains.{{fact|date=April 2022}}

===Distributed processing===
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., on the order of [[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 aligns with the capabilities of Apple's flagship 12-core Mac Pro.{{fact|date=April 2022}}
