Ummmmm.... this is big news for Logic and GarageBand users who want to work on an iPad.
Jason Snell reports that Logic X for Mac and GarageBand for iOS are getting an update today which will include many new features, notably the ability to transfer projects from Logic on Mac to GarageBand on iOS (and back again).
Logic updated with Touch Bar support; GarageBand also gets an update - Six Colors:
Most intriguing for people who switch between Logic and iPad is the ability to export a mixed-down version of a Logic project and sync it to iCloud as a GarageBand project. That project can be opened in GarageBand for iOS—and tracks added to the project on iOS will be synced back to the Logic Pro X project via iCloud.
