Thanks all. I am going to experiment with it. I will read all the documentation that Noel mentioned, and check out the videos pghboemike stated, as well. I have used John's tips of Keeping it simple, before. It works. One time I recorded a whole song, ready to harmonize, only realizing something was not plugged in, and got a message saying to record an audio, and you can harmonize it! It pays to check out a few bars first, and then go. . for sure.
DanL and others are getting good results from it, so I will study it for a while, with just some scratch tracks of no importance, until I feel I am getting somewhere. I do not sing well, (maybe about like Neil Young at best), and I can't harmonize. (Remember that Rolling Stones song,, " When you're down, on your luck, and you just can't harmonize. . . find the girl with the far away eyes")
Muzic Trax has me the most worried, he says, "use a clean, dry and in-tune mono vocal".. Oh well, two out of three ain't bad.

Thank you all, have a good weekend. It's Jose and Music time!!!!
