Not me. If I had the money I'd think about copping one perhaps, see if its all that its hyped up to be.. spending a G or more on a sequencer with some pads seems a little frivolous to me (in the 2xl's case- I understand the 4000 is a lot more than that). After banging on the 4000 in the store a little, I do like how the pads feel.
And I heard the 4000 is like a whole other machine.
Is it true that thing doesn't accept the same stuff as the 2000 or some kind of compatability issue if you wanted to go from using your 3000, or 2000 to using a 4000?
And.....doesn't the 2000 have the WORST sound? I heard those were the worst mpc's by far.
