I have exactly the same problem as the previous posters in this thread so I think that there really is a serious problem in the 2010.5 version of one or both programs. Here is a description of my problem.

First, I load a demo song in Band in a box that uses only realtracks, no midi at all. I generate the tracks by chosing play and it plays fine. I then save it with another name. I load this song in Realband. The bass is in MIDI along with a guitar. The other guitar which should be a fuzzy electric becomes an acoustic guitar. The guitar track that should be a realtrack is there but completely empty. I then play the song which sounds completely different that the original in Band in a box. When I use Band in a box 2010 as the source, this problem does not happen. What gives? Any suggestions anyone? Thanks. By the way, I use Windows 7.

The instruments in the original BB file are All RealTracks: <Guitar, Electric, Rhythm HardRockLAFuzzySync Ev 120>, <Bass, Electric, HardRockLA Ev 120>, Pop Organ & Ac. Guitar. RockHardLA variation 1 RealDrums. I get a midi finger bass 34 instead of the Realbass and a midi guitar and bass. I hope that a patch is posted soon. Thanks.

Mike.
