The first thing to do is open up the ARX slot compartment and flip a dipswitch there to put it in upgrade mode. Then you can load new firmware over USB in it, after that you have to do the same for the rack processor itself. I think it would have been nice if Roland had put these dipswitches on the back of the unit so you don't have to take it out of the rack. Well after this the VS-700C itself (the controller) has to be upgraded as well. But for this you have to install it stand-alone (without the processor) with special drivers. Again some dipswitches on that back and new firmware. Well it took some time but luckily it all worked out.
