Pat, i used Melodyne, both as a stand alone, and as a plug in inside both Sonar, and Reaper. It worked well as long as you did not push it to far, where it crashed either program. AS A stand alone it is great as you know. I also used the pitch correction plugs in both Reaper, and Multitrackstudios. Both worked, Reapers was a bit confusing for me personally. The one in MTS worked very well, no graphical GUI, but the results were very good. The TC Helicon inside BiaB. PT, and RB works pretty good for harmonies if you use it lightly.
