Here is a link to the VST at Sweetwater I am lookming into. It is a choir plug in so that when you record your voice into it, it creates the harmoy for you!

My goal is to have a VST that will help make it easier to harmonize with myself in the points through each song that I record.
Most of the other plug ins I have found are about @200 or so, one was $400! Yikes!!
