I picked it up 3 or 4 days ago and have found it not only simple to use, but simple to get an extremely good result in a very short time. I'm doing only female vocals at the moment, and so far, just wow. Find a preset you like, tweak away until your happy, and move on. It's almost that quick. Not sure about the harmony section. I wish they gave the power to pull the harmonies out to treat separately, but while you have the power to change every parameter of the harmonies, you cannot send it to a separate channel in your mix. A send function please Izotope !
In the last 2 months, I've added Neutron 2 and Ozone 8 advanced, and now this, including Vocal Synth, which I havn't looked at yet. I expect a version of Nectar is around the corner that will include a track assist function like Ozone and Neutron, which will makes things very interesting.
Lovin their stuff and so will you. It's a bargain at $99........
