The second app Apple announced for the iPad 2 is GarageBand. It’s got touch instruments (but apparently you can plug in a guitar if you really want to), more than 250 loops and multitrack recording and mixing. Finally Apple has deployed its own app to turn the iPad into a music instrument, following the runaway success of music app developers in 2010.
An interesting detail: the piano demoed on stage recognize pressure on keys thanks to the iPad’s accelerometer. That’s very neat. The graphics looks really beautiful and you can switch between lots of instruments including organs and synths. You can toggle octaves and the sustain pedal on the piano. Engadget also reports you can tweak the vibrato with your finger as you slide on screen. Plus, drums!
