Thanks,
I've tried the three adjacent key method. It does not work. Yes, it will stop the bass and chords but this is no help when trying to play "stop" chords like in Tutti-Fruitti, Great Balls of Fire or Do Nothing 'Till You Hear From Me, etc. I need for the bass and chords to stop immediately when I lift my left hand off the chord I just played as My X1 does. My Roland G1000 also did that but it was a menu item rather than a button.
