OK... a quick look at the Tone table in the SD-2 reveals that only CC00 is used, so whatever CC32 gets sent by the BK-9 is ignored.

Bank A uses CC00=0, so that means the Capital sounds in the BK-9's bank send this code. So Bank A is 100% addressable.

Bank B uses CC00=1 which most BK-9 PC's have a version (but not all)

Bank C uses CC00=10 which is a lot rarer.

The Presets Bank uses CC00=2, which quite a lot of BK-9 PC's use.

If you compare the SD-2 codes ( http://www.ketron.com/pdf/SD2%20Manual%20English.pdf ) with the BK-9 MIDI implementation chart BK-9Tone&DrumKitList_e2_W.pdf (available at Roland http://www.rolandus.com/support/owners_manuals/ ) you should be able to pin down exactly how many you can address for the RH side of the BK-9.

You can insert PC/00/32 codes into BK-9 styles using the Style Creator software, so the total soundset should be available for style/smf use...

Hope this helps.
