I knew about that, but thanks, George, It is also where you hold other things like preferred fingering types.

Trouble comes when you want specific songs to have Bass Inv on, but your Performances all get stuck on Bass Inv off...

I am looking forward to the Session Manager software being updated for the BK's. It had the capability of batch writing your Performance parameters to any or all Performances you want. And leaving out the ones you didn't.
