I had one but returned it. I wanted to use it the same as an aranger drum section, but I couldn't get it to work for me. Say you have a 4 bar pattern. if you press fill> in the middle it will wait till the 4th bar is over before changing to next pattern. 1 bar patterns were fine but I needed more variation and immediate next bar pattern changes. Maybe I'm missing something. anyways the drum sounds were good.
