Although it was a bit complicated to do, you COULD change your ROM styles on the G/E series into edited ones, so you could call them up with the front panel knobs. But on the BK series, EVERYTHING you do gets stored on the USB and you call them up from there.

It is simply one more thing that makes the old 'Free Panel' system of playing a thing of the past. Mind you, with an iPad, calling the User styles up from USB is quick and convenient, but without one, it's either scroll, scroll, scroll, press, or call them up numerically. Neither is as good as calling them up from the Rhythm Family front panel buttons.

But this is something other manufacturers make you do too (except Korg, at least), and I think they need to reconsider... What's the POINT of all those lovely style selector buttons, if the only thing you can call up with them are the bare, raw ROM styles? Most of us tend to want to edit the factory styles at least a BIT. Which promptly turns them into a waste of front panel space.

Time for a rethink, Roland.
