It really does what it promises. With a couple of clicks I had got a more interesting sound for vocals.
However, it's a kinda black box and I don't understand what kind of effect the settings have on the sound. Just have to go with my ear which of course is in the end the only correct way. And in fact I love and hate this simplicity at the same time.
This, I see, is a very early version, so I'm eagerly waiting to see what kind of advancement it will accumulate during the time.
