I used RB and pulled in a midi file.......worked great only issue is when it did the chord chart it pulled it from the honky tonk piano so the chords were all over the place. When I tried to use a guitar real track using the chord chart it sounded way too complicated. I had to simplify the chords and this seemed to calm down the guitar. When I used ACW with the original song it got the chords closer than the midi file I used. So I guess the jury is still out on which way works the best.....I guess it depends on the midi file. Thanks again for all the advice I am really starting to get some great backing tracks.
