iPad/iPhone App and Server

I need an app and server developed that will display visual feedback on an ipad/iphone based on information received from a server on a mac. The server will receive midi information from music software and that will determine what visual feedback to send to the ipad/iphone app. I need to be able to customize the visual information being sent to the ipad/iphone and save that as templates or presets all within the server app. I also need to be able to have the server display the same information on multiple ipads/iphones simultaneously and in real time. All artwork/graphics will be needed as well. TouchOSC is a good app that will show you a general idea of what I'm aiming for. I want a similar level of professional look and feel.
