Doepfer

I've always been interested in doepfers Frequency Shifter module but 
after been dissapointed with the A-119 module wasn't sure about 
getting one without hearing it first.
All this recent talk about the module has made me want one again.

Does anyone know any websites where I can hear DOEPFERS frequency 
shifter in action?
Or if someone could upload an mp3 to this site would be cool.

Thanks
