Make sure when you are doing some of this troubleshooting and copying and pasting etc. that you freeze the tracks that are right. There was an earlier post that had success generating it in A, then changing it to B and generating it again and getting the right sounding chords. If you do this, freeze them and save them naming them so you can keep track of what you are doing, then put it all together in one song with the frozen key of B parts where you want them. Realband can simplify this process if you export all the tracks to realband and then just do some editing to get it the way you want it. Just takes some time is all. You can save as many copies of the song as you need to get what you want, just by renaming them.
