The new Sounds and styles downloads

Hi I am struggling to get the new sounds in my Kn6500. I have downloaded the files for sounds to floppy disc but when I try to load them, the titles is there OK but it says the file is empty. I cannot of course download the styles file as this is far too big for a floppy disc. Does the Kn7000 have an SD slot.and if so does anyone know of an attachment where I can use an SD card or even a direct link to my computer. A further mystery is the HDSX6 hard drive which is fitted in my keyboard and it is only through this website that I have been able to find a copy of the instruction manual. On fiddling with this drive I find there are entries named Yamatech, which seems to be the name we are expecting for new downloads. All a big mystery to me and any comments would be greatly appreciated. Regards Carper26
