I really like the RealTracks Blues organ sounds but the 7th chords don't fit on many songs. I wish we had more Real Tracks organ sounds with the same tonality without the 7th's. As it is, I use the Background Pop sounds which are good, but sometimes I would prefer the other sound but can't use it because of those 7th's.

As far as I can see NONE of the "Organ B3 background" has a "simpler" check available. Many of the other Organ RTs do. Have to tried any of them to see if you can get a fit?
