Seems they are trying to s-t-r-e-t-c-h the basic model to satisfy two markets...home and pro, or semi-pro.

It still is a quick and dirty and fairly inexpensive) way to get that Roland sound in your kit...but, I would find the lack of style part swapping quite limiting.

Strange, because they included such great features like ON BASS, which makes them quite enticing to a pro.

Maybe they have another update in the wings?
