Q: I am trying to play a drumkit in GarageBand for iPad with the Keystation Mini 32, but can only trigger a few of the sounds.  How do I play the other sounds?

A: The Keystation can send the full range of 128 MIDI notes, you just need to make sure you're sending the notes that correspond with the sounds in GarageBand.  Press the Octave + and - buttons to locate the additional sounds for the selected drum kit.
