Thanks to both of you. I typically record vocals twice and edit them to get a particular sound. I have also done a good deal of double-tracking with Melodyne and have done the old school clone-track-and-shift-time-and pitch thing. (I also have a TC Helicon VoiceWorks+.)
So, no trouble getting doubled vocals. I just thought that if MicroShift were a great and easy solution it would be worth the price. From what I've heard, I am not impressed. The free VX_64 Vocal Strip in Sonar does as well on vocals, if not better.
Thanks very much for your kind offers to help. I was just curious if the tool was any good since it claims an Eventide heritage. Think I will pass.
