Dng,
It certainly work for me also covering many style.

I did not think it could be as simple as the way the save was used.Hence I tried many more styles both customs and Preset.

The success with customs styles was consistent however the success with preset styles was not, not all,but a fair number.Which were the more complicated Styles.

Whether this has to do with the make-up of the pre-set styles I am really not sure.

Anyway it certainly needs to be looked at by Yamaha.
