Hello dear music experts. I am planning on buying a half-professional key-board to instumentalize my songs and also hopefully to play as arranger with my sis. Well, first I saw that Casio board on sale and I was quite impressed. But my research led me to all this other key-boards where the features differ quite a bit.

I am not sure about Roland, but my comparison of Casio and Yamaha was as followed:

- Yamaha has a Vocal Harmonizer, Casio doesn't. So since I want to compose songs, I am probably better off with Yamaha!?

- Yamaha has a better compatibility, I heard.

- I heard, that Yamaha's customer service sucks though - that would be a killer for me, I will definitely need some support....... Casio has a great Manual for people like me.

Anything else, and the difference to the Roland??? Please give me some new ideas here, because I am really not sure what to buy! Thanks, jrudnitz
