Hi Bernie,
KN7 aren't the easiest styles to convert.

I've had more success with some of the earlier ones like KN2,3,5 (to korg as I haven't had Roland in years)

See how you go with the styles James has kindly offered to convert for you.

This may be of interest to you also.
Don't know if you ever bothered collecting Technote Style Disks for your KN's,
but it appears Technote has recreated the styles for Roland Keyboards.
I have no idea how good they sound as they haven't done them for korg.
I was nearly tempted to buy a Roland when I first read about it a couple of years ago.
I miss some of those great old Technics styles & unfortunately a lot of my old disks got damaged over time. Years of storage, the data got corrupted.

Maybe someone who's got some can tell you whether they're worthwhile or not.

I was almost tempted to buy one of the downloads to see if Roland format converted better to korg, than the original Technics.
