Hi arcadia,

Not sure if this well help , but the Tyros 2 as well as the S900 , both have what Yamaha calls AI Chord voicing.

In other words you can do f/x chords with your right hand in the AI mode.

It really is a very good way to play chords on a Yamaha , don`t go with "fingered" just stick to AI and it will work fine.

Also in handles all the inversions that you can think of !!

Take care,
