real time pitch shifting vst's

None of the real time ones I know of (which isn't many) have a triggerable ADSR.
Does it have to be real time for actual live playing or could be an effect on a pre-recorded track?
Just saying cause Waves has an interesting pitch shifting tool but it requires full transfer of the audio file, like Melodyne used to.
Then again, if that kind of thing is ok for you you could probably also use Melodyne.

I'd really rather not have to load up a wave file and adjust the pitch it that way so yes, it needs to be real time.
I just want to be able to use it as an insert and then control the pitch using an envelope in sonar.
If you look at the one in AD you'll see what I mean if you're not familiar with it.
I really like the effect but would much rather use it with my BFD3 kits and cymbals in particular.
Skot at FXpansion said he wanted to include one with BFD3 and it's on his to do list but I've no idea how long that could take ?
