I started won a 2kx and evetually got the 3000.
To me, all these people grabbing and tossing out MPs is rediculous. It would drive me nuts, not to be sure my setup is done and ready for anything.
The key to happy ownership is research my friend. Long before I had a 3k I knew I wanted one...turned onto the looks, sound, reputation.... the usual things.
However, I did my research. Plus I tried as many MPs at other places as I coould find.
So before going 3000 I tried the 1000, 4000 (there were no 500 and 2500 then). No need to cop everything right away.
Knowing the 2000xl inside-out, backwards in the dark with a blindfold on, just a few things suprised me at first when I made the switch to 3k. Let me remind you I had read the manual before I got the machine to get an idea, followed by research etc.
First thing that I knew before I got it but still is kind of a bummer, is the the fact that you can have only 1 PGM at a time, and the only half way helpfull solution is adding a 2nd program and record a pgm change into your beat. Not really the same thing.
A thing that any 2kxl user will ask is: WHERE IS MY UNDO BUTTON?!?
Well there is sequence edit. But to be honest with you. I never use it eventhough it provided pretty much the same thing as the 2k undo, just that you have to set it up manually.... I just realtime erase notes or go into step edit.
Use your brain and you need no undo
Also the copy to zone function is pretty ancient if youre not working with rohans OS.
Makes chopping up a break pretty annoying, for a 2k head.
As others already said I adapted my workflow to this machine as well, and I feel its alot more musical and less mechanic as on the 2k xl. Still I kinda miss the thing I had with the 2kxl. Its kinda like a first love

If only I could fly over the buttons in the same tempo using the 3k. Its all about practice ... So keep in mind what dude posted above. Take your time with a machine. Sometimes it takes one or two years to fully get into it.
Now befo I get out of here let me just give you one hint: The 3000 means : work, patience and concentration. Even more than on other machines imo. Become the Teacup, and everything will follow grasshopper
