The Roland morphing didn't impress me that much although in theory its a good idea....I prefer Ketrons SD-1's approach
http://www.ketronus.com/sd1.html

which worked better for my needs at the time & still today wish It was included in every arranger KB on the market.....
Bass Lock, Drum Lock, Manual Bass, Jump, Arrange Lock.
These powerful real time controls will let you combinate styles in so many ways to accommodate your songs on the fly...Yamaha should take a lesson from them on adding these features, plus allowing Registration setups save & transpose to the MFD which would put them in another Stratosphere!!.
