The pro can afford more than the home user (often!)...

I see no reason why something at the top end of the price spectrum can't give us what we want. That shouldn't scavenge sales at the lower end.

In the meantime, I think we need more and better tabletop arranger modules. Most WS's are sophisticated enough to be able to task their buttons and knobs/sliders to control a really good arranger module. I really like my BK-7m, but would go ape for a BK-9m! Run that from a Kronos or a MotifXF, wow! What a combo!
