Roland haven’t released a new pro arranger for about eight years, so styles for newer, more contemporary music genres are a bit scarce. Plus, the most recent pro arranger (EA-7) utilizes a bunch of kits not in the BK7m, so may not sound correct.

Another issue is that the BK series’ data structure had no direct access to the ROM styles (G/E series had direct computer access to the ROM styles, BK series does not). So to get the ROM styles, somebody had to have saved them all individually as User Styles. Quite a lot of work!
