Was wondering the same.
I would like to know if steinberg/yamaha are planing to release a keyboard controller in the next months, because the ones on the market are pretty disappointing quality wise.
I would love to have an insight from them, I could wait a few month if I knew something is being preparee. But I dońt want to wait in vain.
The yamaha kx series seems good though, but i think it´s discontinued.
