Logic Pro faces some stiff competition from the likes of Pro Tools, but Apple's hoping to bring a few more music professionals into its camp with a fairly major revision of the software. Available today for $200, Logic Pro X brings with it a whole new interface that Apple's Phil Schiller says is "designed to streamline the process of creating professional quality music," along with a number of new features. Those include Drummer, which draws on performances of some well-known session players and recording engineers to provide realistic drum tracks, as well as Waves Tune-style pitch editing with Flex Pitch, Track Stacks to collapse multiple tracks or create layered instruments, and the Arpeggiator MIDI plug-in. Also launching today is the free Logic Remote app for iPad, and a major update to the Main Stage live performance application (it will set you back $30). Additional details can be found in the press release after the break.
