meta-redundant you’re right.
I’ve read the post a lil bit faster. I’ll edit my answer in order to avoid mistake.
So the alesis io dock is allright for ipad 3 but would not be ok for ipad 4. You can use an adaptator, like it’s described here : http://community.alesis.com/alesis/topics/ipad4_and_existing_alesis_io_dock but the ipad wille not sit in the dock properly. Behringer istudio thunder is probably a better solution so.
One more for the apple connector policy…
