With Ableton Link, menubus, & internal MIDI, it's become an inspiration even if the tracks never make it into my work. I feel it's a lack of imagination on my behalf tho. I'll be exploring further as time allows but yeah-the iPad is now an instrument. A ton of 'em. I'll update w/ the instrument apps as I explore. Definitely not to be discounted, even if it's not your bag. Lord knows I never thought it'd be part of my stuffs.
