I purchased my iPad primarily to use music production apps wherever I go. Of all the apps Ive tried, the Gadget comes across as the most full-featured and polished. Nothing about playing notes feels clunky, you can automate anything, you have full scene and track support, even extensive MIDI support! The built in gadgets remind me of those on the Korg Electribe 2, but better in that you can record 16 bars per track with more parameters to control. I havent tried out the sampler DLC but theres an incredible amount of power out if the box. The only 2 features Id say would make it better are audio tracks and external MIDI instruments, but theres something to be said for how tightly integrated everything is already.
