I'm looking to get a midi keyboard I can use with my ipad as well as my macbook pro and pc. Initially I was looking at the akai synthstation 49, as the ipad dock is cool. But as its not released yet, and looks to be expensive. I decided to go with a normal midi keyboard and camera connection kit combo. Can anyone recommend some good midi keyboards compatible with the ipad? I've been looking at the M-Audio Oxygen 49 - 3rd Generation, but was wondering if anyone had some other recommendations? Also, would other usb connection kits work (the cheaper ones), or would I need apples unnecessarily expensive one? Any help is much appreciated!
