Had a fiddle with this at a mates place (got it with a bundle or something) and after the tedious process of setting it up AND reading the manual i got some results. Point of the plug is to input one sound L and one sound R and then morph between the two (basically crossfade and bandpass) with a big old slider on a psychedelic background. Oh and theres a reverb. At first we thought it was just a reverb. But it wasnt. Anyway as always its down to the user to make it fly but after a whole day of screwing with my proteus the morph slider felt weak to say the least. Still, got some nice results from it.
