You still don't get it. The ACW will give you a layout of all the chords in the song so then you can add RTs, RDs or midi parts. It also generates a tempo map.The parts you add will play along perfectly with the original audio file.I've done this many, many times. I produced a commercial CD for a band recently and used the ACW to add RTs after the fact. Here's a link to the CD.Tell me which tunes I doctored up using the ACW.
