A classic sound, loud, techno, boom boom. I like it, easy to program, easy to use, expressive enough. OK, if you want variation you need to turn knobs, but the (meanwhile > €2000) original also has that as a strength. With this machine you get an original, with more control, and some FX, and full midi controllable triggers. Behringer did a good job on this one.
One minor remark on the "keyboard style" programming knobs. They are rubber pad contact ones, and on my particular machine, the last four knobs have a slightly different feel. For the rest, I'm fully happy with the machine.
