No, i'll not base my decision on the vocal harmonizer features alone, I already made up my mind on the Audya. I just want to know ahead the comparison between the two as I owned TC Helicons and also previously a PA800 which I'm happy with. I do not have experience with the Voicetron but only with MidJay optional vocalizer which is not a true harmonizer.
I'm happy to hear from Nitelife about the Voicetron.

I'm also waiting for the new MidJ Pro which supposed to be an ultimate all in one music box module. Rumors said it has full featured vocal processor/harmonizer.
