diki,
i understand and agree a chord progression display would be very helpful for intro 3 on roland. right because the lack of it, i dont use that intro so much. neither the ending 3. i prefer doing a little bit of intro playing piano with no accompaniment and after that using intro 1, being so short.
the reason why the guys just relax and let the keyboard play 16 measures intro is simple: they have to show how easy is to "make" great music. remember, the non-pro market is much bigger than the pro. especially since tyros is targetted as a "home hobbist instrument".
