I haven't had a chance to give it a hand's on demo. Every demo I've heard from them has been so cheesy and unnatural, I have to wonder if it's a big joke. I should check one out. I just need the simplest of things- an octave up, an octave down, that sounds pretty damn close to my (or any real human) voice.
I really don't understand TC Helicon's line of pitch correction, effects, bla bla bla (beyond obvious financial incentives)... every singer I know would buy a box that let them access clean octaves up, down, a realistic double, and just maybe a hold feature... with a clean split to the soundman so that he had a dry vocal to fall back on if anything went crazy. It would be revolutionary. Anyone who needs a tuning pedal for their voice.......... I don't know. You might have other things to work on before getting into vocal effects. I have been singing my ass off for 21 years and have a lot of control... now I have bad ass special FX (and a decent double) from the eclipse and pro compression from a distressor... I just *have* to find a passable octave effect.
