Hi bharris

I do not use JABB anymore since RealTracks/Drums but I think that you do it in JABB - someone will know here

But I do remember this happening and it is because of the difference in JABB which was not GM compatible - in other words channel 4 in BIAB may be channel (say) 7 in JABB - you just have to locate whateaver channel it is but do not change it to 4 - EXAMPLE BIAB melody channel 4 - this plays another channel in JABB say 7 - as long as you save the correct "mismatch" setting it is easy
