I would like to see a combination of the loop and arpeggiator features from keyboards like the MoXF combined with the normal arranger functions from the Tyros series. They are quite different in sound, and functionality, but I feel that unless we want to lose the younger generation to WS's altogether, at some point or another (the sooner the better, as far as I am concerned) we need to be more inclusive.

On the other hand, perhaps the arranger's directed loop flow paradigm could become better implemented in the WS's, and Yamaha can let arrangers slip further and further into tools for only the elderly to make music on...

You need to find whoever designed the original DJX (not the awful MkII) and have him design something using this century's synth and arranger technology. Then stand back while the orders flow in!
