I am a bit confused by the SD7 file system. As far as I can see, if you have a style to save it can only be placed in one of the ten places, ie User/Ballad User/Pop etc. So if I want to save styles as follows :- User/Latin/Fast - User Latin Medium - User Latin Slow it cannot be done unless using the Media button but then everytime a you finish playing a style pressing the media button takes you back to the first style in that folder. If there are lots of files in that folder then it can take some time to get back to where you were originally.
On the Yamaha system it is so simple. Create a Latin folder then a sub folder Latin Slow etc. and when you finish playing a style by pressing the style button on the screen (option D if anyone is familiar with the Yamaha Tyros) it takes you straight back to the style you were playing. No messing, total continuity.
I can create sub folders within the main ten folders on the SD7 but they do not show when selecting styles.
I hope you can understand the problem and I welcome any input whatsoever.
