I exchanged several emails with product support without much help. About the only thing they could tell me was to uncheck the "generate real chart" in the preferences. I had already done this before I contacted them and it does not stop the midi copy of the inserted rift. At this time I am using the track drop down and removing the track with the midi data.
I'm not sure they know what the issue is or maybe it's not a big issue for them.
Anyhow, I still love the version 2013 of Band in a Box and RealBand! The backup tracks that I make in my studio using Real Tracks, my telecasters, wife's piano and using a Boss BR1600 for the final mix, rivals anything that comes out of the big boys studios!! They must hate PG Music...or wait...they might be using Real Tracks!!
