I'm mixing a guyz that is doing west coast funk gfunk electro , he's using a lot ovox (witch kills my session cpu lol) , pretty versatyle , for me sound wise i love vocal synth but it's really cpu heavy . Softube seems great if you're stricly about this sound .... in vocalsynth you can mlix diffrent type of algo witch is great , i love that airy breathy control for exemple to add to main lead to bring intelligibility to vocoded vocals ...
