Yesterday, after its iPad event, Apple released an updated version of GarageBand for iOS that includes a few new features. First is Smart Strings. Similar to the other smart modes, Smart Strings makes it easy to control a set of string instruments and to have them work together to create music on the fly. There's also a new note editor, as well as iCloud integration that allows you to push a track to iCloud so you can then access it from your other iOS devices. Lastly, Jam Sessions allows multiple iOS devices to all play together, mimicking a live jam session. Pretty neat. You can download the update now from the App Store, or buy it for $4.99.
