You will need to check in the manual about what the BK9 stores and sends over Midi, (Hopefully Diki will chime in as he is familiar with the BK9) as every arranger manufacture is different.

NOTE: As arrangers are designed to be self-contained their Midi capabilities are usually limited, thus an external Midi keyboard is handy to have as they can control everything.
