Hello all, im looking for a piece of software that preferably runs in OSx but will settle for windows based if i have to that is capable of a stand alone real time auto tuning (pitch correction) software for a side project of mine that will use a usb mic as the audio input.

All iv be able to find are drivers or add ons for host programs like Cuebase and financially most of the host programs are out of my price range =(, if anyone has heard of anything id greatly appreciate any input.
