I need a little help finding the right rack mount. I have a Yamaha Motif that is now virtually unplayable because of the keys popping out of place. I bought one of those new Casios with the 88 weighted keys. It's very nice to carry around but it's basically a toy. The sounds are really not that good. Anyway, I'm looking for a really good rack mount to midi thru that Casio. I am looking at the Motif modules and I know what they can do. Is there anything out there better than the Motif module? Here's what I'm looking for: I need to be able to split the keyboard into 4 sections with a different sound on each section, I need a really good piano sound, a really good B3 sound and some decent horns. A sampler would be a big plus too. Any help would be greatly appreciated. THANKS!!!
