a while back the propellerheads website did an artist showcase featuring a Guy Called Gerald. In the interview, GCG mentions he performs live with two laptops and basically DJ's with reason. I didn't really understand how that was possible, but thanks to Propellerhead guru James Bernard post today, I get it.
Its an interesting concept for being able to do a live show by effectively "DJing" with your own tracks. Of course you have to have a full range of completed trax, but this is pretty cool!
Update August 2010 :: James Bernard has done a video tutorial as part of his 52 weeks of Reason tips.
