Yes, Roland has ON BASS capability, but it is not the same thing.

Hi Ian, you're absolutely right on 'both' points. smile
I of course play root chords including their inversions as well, but rootless voiced chords simply adds more to the musical palette to pick and choose from and keep the music sounding "fresh & interesting",
especially when playing in full keyboard pianist mode or when the LH part is assigned to piano, organ, or EP, and of course with the LH keyboard part activated & heard.
Speaking of, go back & listen to Jimmy Smith and Tony Monaco cool They both include plenty of rootless chords & chord progressions when they play.
