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 had the option of running in 64-bit mode, which allowed 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 were still compatible, but would run from a 'wrapper' inside Logic Pro itself. On December 9, 2011, Apple announced that Logic
