Here is a post I wrote to Richard on the Roland arranger site..

Richard, there is a problem with the BK's that bothers me....and I need to have a hands on the BK9 before I consider it...I do have a BK5 now..

When I edit on my G70 (SMF) and save common edits via make up tools, and try them in any BK , it will play, but drums are piano...(same problem with earlier models like the E600)..The biggest problem it causes the make up tools in the BK from recognizing it as a SMF...so we can not edit on the BK..

I know the problem..I can remove specific system ex files via the G70 and resave the file for the BK...Too time consuming for something that works fine on other previous models..G and E series(E50,E60)...I call it a bug...and it needs to be fixed...Here is a file you can test on the BK9...Freeze feature does not fix it...
