I have a Motif 8 and I love the sounds! The Motif Rack gives you more polyphony than the keyboard models. Thats the biggest difference. One of the big complaints about the Motif is that the user interface is a little difficult to navigate and manipulate. If I could do it over, I would have got the Triton Studio, and a Motif Rack. I think you will be happy with this unit. The Piano, Rhodes, Organ, and Drum sounds are some of the best "out of the box" of any sound module on the market. Check out
