Have you taken a look at the PC/32/00 codes for sounds on the SD-2 and BK-9? I would be very surprised if there isn't a fair amount of overlap...

At the very least, you'll be able to call up the Capitol Tone (which one HOPES is the best variation of the sound) and quite likely, some of the more established Variations (these have been standardized over a decade).

Will you be able to call up ANYTHING using existing Roland PC/32/00 codes? Doubtful, but you should still be able to call up quite a few...
