Hi,
thanks for the answers. I hoped with this occasion it was goint to work (they asked 2500-3000euro). It is to expensive to upgrade the mac, and then this is ex an upgrade to v4.
I need three 42" plasma's to run video's sync and they need to be triggered by midi. I'm going to look for an other sollution, catalyst looks great to work with. Maybe some on some other project I run in to it.

I'm from amsterdam, the netherlands by the way.
