Fran I had a G70 and I have to say it sounded great probably the best action and key size of any arranger. It's too bad the OS was so 20th century otherwise there was a chance I would have kept it. Korg's Songbook and OS was beyond it and I believe the new MFD system for creating gig playists ( something I use all the time) will be the same as what's on the s910. Very flexible and creating an MFD entry is simple.
