has anyone used the pitch correction software oberheim OB-Tune with Sonar? If so, have you gotten it to work on windows 8.1?

I try to steer clear of pitch correction software. Of course, I'm sure there are many who think that I should get better acquainted with it.

Do a search on OB-tune and you'll find plenty of responses. But, bear in mind it's about 10 years old, is simply a lite version of Auto-Tune, requires iLok, works only on mono tracks, and is a DirectX 1.0 plug-in...so I wouldn't get my hopes up that it would work with Windows 8.1.
