You MIGHT suggest they take a look at re-voicing ALL their styles to avoid the 'jumpy fill' problem, much discussed...

In fact, upping the fills from a meager three might be the main thing to get them above the competition...

Oh, and while you are at it, how about them bringing back the Chord Sequencer they USED to have in the i-series, or even better, take a look at how Roland implemented it...

And how about a Karma arpeggiator?
