Well there is enough to play with. Personally I am not waiting for a new arranger but software for my iPad is always welcome. Waiting for the Korg Triton for the iPad. It’s already there as a vst.
I am with you there, i really love the korg gadgets on the iPad, i really hope they will announce AUv3 support at Namm for all their synths ..
Ipad is the perfect affordable platform to expand your arranger..
Also there is a rumor of full Reason racks releasing for ipad, that would be great..
