Becuase it's old news ? Because no one admits using it ?
Tried others, but Auto tune is still leading. Especially when it comes to more critical situations when you DON'T want it to sound autotuned. Or when you insert it on a track to have it run in realtime. A kind of "set and forget".
Guilty as charged, I admit... I use it....but only a little, sometimes..
Only bad thing, wich keeps it from getting a 10, is that the current 64-bit version 7.5.4 crashed a lot in my Cubase 7. Looked around the net and found that others had the same problems. But no one had really gotten a real reply from Antares so far. I never had trouble with the old versions.
Important to add: had these problems the first weeks. All of a sudden it all started working just fine but I haven't got a clue why. So I rate it up from 5 to 7.
