Sweentech: thanks so much for trying the USB for me. That's great news. Your earlier posts about the differences between the GW8 (which I have) and the BK7m prompted me to compare the voice and styles lists of both instruments and it seems that the BK7m has so many more voices and styles in the categories that matter to me, so with this USB question now resolved, I'm definitely buying the BK7m now. Thanks again!
