My opinion is if you pretend to play or sing it it's fraud. If there's no open deception that's simply using the tools available.
I sing the harmonies I can and many more are covered by a voicelive GTX. I don't move my lips and pretend to sing lol. That would be fraud.
Agreed 100% (I use a Voicelive Play myself). That said, while I think lip syncing (etc.) is fraud in general, I can sorta understand why the big boys/girls do it. I mean they're on nationwide/worldwide tours, performing night after night in different venues 'rain or shine'. People are paying $100's of dollars to see them perform their music exactly how the envision them performing it in their head. They simply can't have a bad/off night thanks to a sudden cold, hangover, etc.. Is it 'fraud' to 100% guarantee their fans get what they expected?
