[PD] searching Time Stretch. vst-fx

[Lazzaro Nicolò CIccolella]

Hi,
someone can suggest where i can find a (free, or better, a *gpl) vst
plug-in that run well in PD for perform a (realtime) basic
time-stretching ?

I have found various vst-fx pitch-schifting stuff but nothing for
time-stretching.

p.s. The accuracy does NOT import me, the project dont is sound
designers related,
but regard a demo (educational) performance for cildren.

thanks
