Apple announced and showcased a new update for its GarageBand iOS app today, which included the new Jam Session feature, which lets you invite up to three of your friends to band (pardon the pun!) together and wirelessly connect your iOS devices so that you can play and record as a group. Jam Session will automatically synchronize the tempo, key and chords of your Touch Instruments to ensure that everyone sounds fantastic together. After you’ve jammed up a storm, everyone’s tracks will be automatically collected on your iOS device so that you can edit and mix them. Also included in the GarageBand update is Smart Strings, a new Touch Instrument that enables you to play an entire string orchestra with just one finger, as well as Note Editor, which lets you fine-tune a Touch Instrument recording rather than just playing it from scratch. The app is fully integrated with iCloud, and you can share your finished songs directly via Facebook, SoundCloud and YouTube.
