Thank you all for your responses above. Most of the time (99%) the SD card will be for just Styles & Registrations, so it appears generally un-branded SD's are not a problem.

Interestingly at the recent 7 day Keyboard festival UK. Technics did an evening concert spot which included Sara Raybould singing to a SD Audio backing of Gospel Singers from one of the 2 accompanying KN7000.
