Thanks Scott! I know the new Roland LX-17 has a Leslie effect built into their organ and I was really hoping the Casio Grand Hybrid series had it too. For me it comes down to finding a Casio Hybrid and the LX-17 to try. Both pianos sound really good online and their features are very similar. The Kawai CA97 sounds a little to compressed for my tastes with its pianos. With the MP10 that I "had"; its sampled sounds were to compressed in the recording process and I hear some of the same effects of this compression in the CA97. I don't hear much, if any compression being applied to the GP-500's samples. I hope to play both the GP-500 and LX-17 soon and will report back here my impressions. Thanks again!
