6/5 for this one. What a blast the Trigger Riot is. Without the slightest hint of doubt the most fun "drum machine" I've used to date (and there's been a few). The experimentalist's dream, I'd say.
Doesn't ever let me down. An absolute breeze to program too, in my opinion, as it's all very logical. The only down side being that the space between the knobs and the cables on the right side is a bit small, but it's really nothing major.
