I'll say "Clouds" from Mutable Instruments. Incredible module for sound design stuff, u have a lot of fuctions in this super cool module, u can also "freeze" the sound, and than u can play with it (changing pitch, adding reverb/delay, cut the greeze sample into small pieces and so on).
Yeah. I think that you really need a Clouds

And maybe, 4ms SMR.
