A few weeks ago a utility for the BK-7M called BK-7M Editor was brought to my attention in the forum. Since then I have secured same and have been using it for a number of weeks. My only regret is that I did not have it months ago and it would have saved me hours and hours of time putting together my lists and renaming songs, and this is only part of what it is capable of doing !!
It is really a fantastic time saving program for anyone with a BK-7M and well worth the 15 Euro. I would support in full other complementary comments made in the forum and is well worth having. Have a look at it here; http://www.gfssoft.de/
