Of particular interest, the new MS-60B+.  Bax have the guitar version, listing here. I imagine the operational description will be common to all the new + units. If those 'scroll' buttons do what I'm hoping they do, they will be a massive improvement on the current unplussed version - its patch cycling is its real Achilles' heel. @Dood, if you can get your hands on one of these for review, I will be all ears. Eyes. Whatever.
