Nobby,
Yes, I control the whole 2000 with the Casio. It works great! Also, yes, the Casio chords are opposite the Yamaha's. I can do it both ways now after playing them both for a few months. It does become confusing at times but I will stick with the Casio way for now. If I figure out how to get the chords to play the Yamaha direction I will let you know.
The Casio WK-1800 is nothing fancy but the keys are a bit more rugged than the Yamahas and I just like having those extra keys! It was an inexpensive way of getting a 76 key board. The styles I play through midi out through PSR and they sound great. The Casio alone sounds pretty good anyways but it does not touch the sound quality of the Yamaha. The Casio has a great sound system with lots of bass and you can use DSP on it also. I only paid $365 for it.
Hope this helped. I had this at the end of my last message in the previous thread.
-Linda
