I get great results with my Personal TC Electronics "Voice One" and also thier "Voice Prism" it runs about MSRP about $700.00 for the Voice one. and $1,500.00 for the Voice Prism. I'm sure it's much less in the Big discounter's stores or mail orders.. mine cost me a major fraction of that, Because we bought 5 units plus several products like it that were year end models such as effect units all from the same manufacturer in the same order to save shipping. We have had alot of problems with the "Antares" Auto-tune (ATR-1 ATR-3 & Pro Producer) products and sold all of them except the plug-ins for our recording pc's we still use just for comparasion. Not for tuning.
On the "Other Side of the coin" Kid Rock used it on "Only God Knows Why"
in the studio as an Effect. If you listen closely you can hear the intonator kicking in and releasing. That was an Antares ATR-1 Vocal Tuner.
EVERY CD released.. No matter what anyone tells you in the major industry has vocal tuning done to it before pressing whether the artist thinks they are perfect in pitch or not, because NOBODY is exactly dead on pitch perfect. If they think they are.. Have them walk on water for me in front of my eyes.
Send me the CD if they are. I definately want to hear and meet them.
Hope this helps.
