I have never and never will, write a review about something without knowing what I am talking about

I always test for several days if I am going to give an opinion..

And I always do a comparison as a benchmark.

It will take more than a new Roland to persuade me..
I have owned every Roland arranger and still pass over the BK9 and for that matter the EA7..(available).

My opinion of the SX900 is based on the comparison to the Genos.. As folks want to compare the two.
The Genos is clearly the top model and the SX is no match.. Compare to other keyboards in the same class... we will soon see.
