Don't you think the Linn Drum 2 would be a better comparison because it actually can sample as opposed to the Tempest and is therefore like an MPC? Still waiting for that shit, I hope when I am ready to move from my sp 404 to something bigger the Linn Drum II is out so I can cop that

As for the Tempest vs Ren debate, probably Tempest? It seems to be good at doing what it's supposed to do and appearently it has a lot of potential, the mpc on the other hand makes sceptical, they couldn't even get the Hardware OS right last time, how are they gonna make the jump to software without that shit being full of bugs?
Plus, the Tempest has a compact and sturdy build, the first thing I thought when I saw the new MPC was that it looks pretty cheap... even cheaper than the 2500.
