multiple display on my pc

[bandinhand]

hi guys I am a music teacher and I started an ipad band with my students with a mix of ipad and andrioid tablets. when they perform on stage i am trying to find a way to give a multiple audio visualization display of all their tablets on a single screen with a multimedia projector and using apple tv is there an app that can allow me to do this?

I've never heard of one. If it exists it will probably be some kind of conferencing app, and will be tied to a web service. That's where I"d start looking at any rate.
