Thanks for the info guys.
It makes sense to just drop video clips on the beat but I always thought that was no good because it doesn't 'snap' automatically to the exact position of an audio transient, or simply drop at a bar position, I should probably give it another go.
Wow @ Resolume, this is cool I need to look into this some more. With a program like this and Reason's soon to be midi-out capabilities or even SDK 2.0 surely soon something really interesting will be possible, maybe even in a few weeks!
Thanks again, off to look into Resolume some more.
