Well, I don't really get how a program is emulation the registration.
Of course I can also use the OneTouch feature to have my favourite sounds always ready, in fact I do that also, but a registration changes in my case much more than just the right hand sound. It affects all kinds of settings, for example the equalizer. Which I find important because I use different kind of bass sounds or bassdrum sounds which sometimes need a little bass boost or in other times have to much bass freq. You see?
And anyway my concern is not so much the selection of the right hand sound, but more that: selecting the next piece is in my case is always equal selecting a registration and I find tht kind of "unpractical" how the X1 handles that. And I suppose that everybody uses mainly registrations, right???
