Are you joking? The P2000 has one of the most singularly fiendish patch architectures in existence. Trying to keep track of sound and map parameters and how they interact, the map modes, which sound you're editing at any given moment, and then editing all of it with three LCD digits, a single pot and a button... It's one of the single most tedious machines I've ever used - even editing the MKS-7 in its numerical "engineer mode" is a masterpiece of human-machine interfacing by comparison.
Having used this for a bit yesterday, I can see it's going to be a lifesaver. Being able to go to the "Map'" tab and see every single parameter transform at a glance is going to save hours of frustration - not to mention being able to bring up ADSR displays to see exactly how the sound+map envelopes are interacting. Sample mapping is still relatively impenetrable, but being able to see what samples and how much space is in each bank makes multisampling a lot easier. One thing I like is that you can build a whole multisampled patch entirely in the editor, and then just hit "Transfer to Prophet" and away you go.
Even if you're just using factory samples, you should grab this to back up your disks - just click on "Transfer to PC", wait for the informative progress window to finish, and then save it to disk as a single handy file.
