My comments assume that these are .kar files
If so try opening one in RB and see what happens. I used to use .kar file exclusively in RB to make all my cover tunes
Yes, I tried right now to open it in RB, and it was more "normal" there, except for every word that is over two or more notes was separated by space...
I hate using RB, because it NEVER EVER works without some strange problems for me.. Like this time, I tried to bring in Kontakt as VSTi to play the melody, but ALL of them was refused, saying it is not a valid VST.. I tried BOTH 32 and 64 bits... And one I was able to open, gave som strange sound that it NEVER gives in BiaB... So RB ONLY makes headache to me and has ALWAYS done...;)
