I had one when they 1st came out in 97 and I made my 1st EP for Kne' Deep and a EP for High Octane on it. They can be a bit tricky at 1st but once you get your head around the idea of hardware sequencers rather than computer software then it's a doddle. They are really stable and quite well built but when your looking at a tiny screen for hours on end it can get a little straining on the eyesand neck. I know that Mark Hawkins uses one when he does his live set and that's pretty full-on Techno.
