looking for a VSTi that reacts to audio

["Michael Peters" <mp@mpeters.de>]

I've already included an audio-2-midi vst in some of my setups, but what 
I'm
dreaming of in the moment is a VSTi (say, a drum machine) that takes your
audio (not your midi), tries to find rhythmic elements, and creates a 
groove
based on them. Something like a virtual drummer. Rayzoon has a "virtual
drummer" VSTi but it needs a midi pulse for speed. I want something that
only reacts to audio patterns.
