Thanks so much! All working now with your suggestions!

I did discover that equalizing tempo does not always do the right things to a song if the original performer had some speed ups that were stylistically correct. I also discovered that the chord wizard picked most of the chords off of the bass notes of this rock song I was using which were not always the root of the chord and thus the key was incorrect. I can see that one has to be very careful. The stems were very usable for me though as practice files for bass playing. I could solo the bass for learning and then mute the base for practicing over the rest of the track. I also noticed that the quality was not as good sonicaly as the Lalal.ai utility, but certainly usable and of course no extra cost! What an interesting adventure.
