Bachus..., sorry, but I don't think you are really understanding this. Yes, the MXZ has some new features aimed at drawing in the younger generation, but what you fail to grasp is that even though there are new EDM kits, and a few new modern styles using them, the traditional styles GREATLY outnumber the modern ones. The realty is that it's more traditional than modern when you look at the actual number comparison.
Casio took a traditional arranger (left AlL the traditional styles in.., along with the recording and editing tools), but pushed their traditional arranger up the ladder by adding the pads and a sampler. Yes, they added Hex Layering.., but this isn't really anything extraordinary when you look at the comprehensive sound editing available on Korg's arranger line.
You're completing missing the point of the MZX, and your claims about it are just flat out wrong in many cases. Granted, it may not be to your liking in the traditional area.., but all the traditional content is there.
