Rejoice, musicians and audio mavens: Apple unveiled a new version of Logic Pro today. Logic Pro X includes a new drummer feature that'll play drums along with your song. There's also a Flex Pitch feature to easily edit the pitch of an audio recording, and a remote control feature that lets you control Logic Pro via your iPad.
Apple also updated MainStage to version 3. MainStage 3 is a live performance companion app for Logic Pro; the new version features a fresh, new UI and compatibility with Logic Pro X.
Logic Pro X and MainStage 3 will be available today from the Mac App Store for US$199.99 and $29.99, respectively. Logic Remote for the iPad will be available for free from the iOS App Store. Apple has a page with what's new in Logic Pro X here.
