i downloaded that thought i'd give it a try. not really worth it in my opinion. i loaded in a couple of songs i knew just to verify. the easy songs it got the chord progressions right, not so much the basslines. but then the song was so easy, so why would u need a program to do that anyway. i did a more difficult song, and it missed so much of the changes that you would play (not stuff that you would skip over or play around), that it was pointless. you would get more of the song just doing it on ur own.
i used the trial version so maybe its limited. but i think that the software is more geared to particular styles of music, gospel not being one of them. just my humble opinion.
