Donny.., I think that's a great idea.., but "ignorance" will destroy this entirely. The problem is actually on both sides of the fence too. You'll have di-hard synth/workstation buyers saying "ain't no way.., no style or auto accomp on my workstation". On the other side there are even arranger players who'll say "no arps, pattern sequencers, and deep synth engines with fully expandable sampling.., no no, not on my arranger".
Could you imagine the cost of that unit alone as well. The pro arrangers already greatly surpass the average price of a workstation. We're bitching now about a $5,000 Ketron. Get a company to merge the two and $5,000 will be the price for the BASE model.
