Just can't find anything like this.

That's because it's not very easy to make (decent) real-time pitch shifters in Max. It takes some time.

On the other hand, you could look at [gizmo~].

But if you are willing to be more adventurous, [fiddle~], [sigmund~], and [pitch~] could help you, as well as a lot of math!

You can also do some real-time pitch shifting with [phasor~] and [tapin~]/[tapout~] --- [ http://www.youtube.com/watch?v=uyzY_ZP54pA ].

However, it may take some time to make a 'successful' real-time pitch-shifter this way.

Thanks, I'll try it.
Isn't grainstretch~ only for Mac?

I also found that Grain Delay gives pretty similar effect.

there is a windows version of the external in the package as i see. i will def. try that out too. the video looks promising (realtime pitchshift at the end of vid) i used gizmo~ in an fft patch so far but it adds latency.
