I had the opposite experience! I had a 3000, sold it for Maschine and MPK49, then just could not stand the Maschine's inability to perform live without a computer.

Despite my MacBook's great specs, I would literally experience software issues involving a crash during a performance 1/5 times to the point where my bandmates said they'd help me buy the 3000 back. Based on what I've heard from other touring electronic bands, there's a lot of the same. Which makes all the sense in the world, as we're literally talking about a dedicated piece of hardware with integrated firmware, vs. a VST, in a DAW, on an Operating System. That's three levels of abstraction.
