I have the 2000xl.......And it is like the heart of my production. I have been producing for about 7 years and the only other peice of equipment that I have purchased for production is the Korg Triton Xtreme. I have never used the 1000 but I have used the 60 and the 4000. They are all very similar. That 4000 is mad complicated though so I just stuck to what I know.
