This is really a suprisingly great plugin. You can really get some great result if you put some effort into it. Try to use several plugins at once to create a choir, for a free VST this is amazing. Check out the video review: https://youtu.be/BvgAYGM1_Nk
It was the result after testing out the 'Alter Ego' VSTi plugin for the first time in my DAW about one year ago (in Zynewave Podium) :DD :-) Nothing special, but quite funny...attention, the lyrics are extremely dirty, in other words; Marie Ork acts very horny on her singing performance, so only watch it, if your sense of humor is compatible with stuff like that :D) Have fun watching/listening! :-).
