It could be in a new OS, it could come out on the NEXT G-series, it could come from another manufacturer, I don't care!

The frustrating thing is, Roland already have the code! It's not something they need to develop. They even have four well placed buttons (the Mark/Jump buttons for SMF play) that could do double duty and not even change the form factor. It is entirely a marketing decision, rather than a player decision.

Why pull a feature OFF of a keyboard if it was A) unique B) worked perfectly and C) you already have the code and controls?
