Like simple pitch correction, it's just a crutch for the talentless until someone starts misusing it. Which is where techno comes in. The rhetoric may be futuristic, but when it comes down to it, techno was constructed with technology left around after it went out of fashion in the mainstream.
As for Celemony Melodyne -- so far all the software they've done has been very well done. Antares Autotune was the pioneer, Melodyne finally got it right. It's a blast to play around with. The company has a reputation for delivering what they promise. I'm a little skeptical about the claims for sound quality. It might pass muster in a full mix, but any time you muck around with recorded audio, especially something that listeners are highly familiar with, like the human voice, piano, etc, even minute changes in timbre are noticed. And then there's the 'uncanny valley' from animation. If you change a vocal part to something too far from what is naturally singable, or give a guitarist the ability to play 10-note chords, it's going to sound weird, even if there are no audible artifacts in the processing. And by and large, it has f*ck all to do with Detroit Techno.
