completely weird prob

[PaRaNoId]

First off- Using Sonar 3.0 w/ Aardvark Q-10 interfaces, PC is AMD athlon XP with all the necessary components, etc....

I had inserted OBerheim auto-tune on a vocal track within SONAR and tried to see what it would do. Decided not to use the effect, so I erased it from the "effects bin"(like the insert area in PT) and the track still sounds like the auto-tune is on it. I DID NOT apply the effect permanently to the track ever, just tried it as in insert. However after rebooting, disabling the effects bin, and even pasting the take to another track, the auto-tune is still there. I will never open that plug-in ever again now...Does anyone have any idea what may have happened? It makes no sense to me at all...The singer is p#ssed too! Now i think i'm starting to hear the "cher effect" on files that never even had any autotune applied!...BTW- My DAW never has been connected to the Net.
