I have a video of a left-handed pianist who found trying to play the piano in the usual way became so frustrating, he had a piano especially made to accommodate lefthand playing. It is really fasccinating watching him play, but I hasten to say he is a professional and plays so well, it is a great pleasure to listen to him.

I'm wondering if it possible to purchase a left-handed Tyros keyboard? If so, this could be the answer for your friend. Mind you! I do think it would be cheaper and easier if there was an on-board dedicated button for him to be able to move the accompaniment chords wherever he wanted.

For now though, I would try moving the Split point and use the Harmony/Echo button (chords and/or octaves etc.) It can make a big difference to how the keyboard sounds. Interesting though!
