Marck, I guess this might help. I work a lot with both traditional styles of music and more synthesized, electronic groove oriented material. It sounds like I'm trying to have my cake and eat it too by finding one all-inclusive keyboard. It sounds as though the 9000 is better for traditional styles whereas the MOTIF might be a better choice for the other stuff. If so, my concern would be whether or not the 9000's audio quality is suitable for the studio as the MOTIF is. Also coming more from the PSR tradion, I wonder which of the two would be easier for me to learn.
