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.
