Here is a link to the thread at Roland-arranger.com for the new BK-7m OS... BK-7m v1.06

It adds many new features, fixes several bugs and operational missteps, one of the most important (for me, anyway!) is the ability to write your own OTS settings.

Kudos, Roland!

It seems that some of the BK5 OS features are being migrated over to the BK-7m. Outstanding!
