You could use USB overdrive http://www.usboverdrive.com/USBOverdrive/News.html. It turns any usb device into a midi controller for only 17 euro... Works fine for me

My mistake, i ment the thunderbolt cinema display with 2 thunderboltports indeed. I second your comment but remain mac-fan because of some other features...

But: Macbook pro 17" could have 2 thunderbolt ports too because it has en expresscard slot wich can be converted to thunderbolt.

Unfortunatly not. Unless you use à MacBook pro 17" wich has 2 thunderbolt ports.

Any chance that fix will also be done for R3? Would be conveniant to use ipad as 2nd screen for preperations @ home.

and another +1

I have the same issue so would love te hear the results on that one! It's quit an expensive device so would like to be sure it works...

Tip for countdown: use a quartz countdown: that's connected to the internal clock of your computer so will never be off time even if you don't show it for a while...
