I am using Caustic 3, Korg Gadget, and Garage Band for some sequencing on the iPad but I am also experimenting with using the arranger functions of the KMA with the sounds of iPad programs like Galileo, Nave, iLectric and iGrand, Sound Canvas for IOS and DM1. It's all experimental so far but I hope to use this system for songwriting and creating backing tracks for my live act.
