Actually I do things like this all the time, and Andrew, I mostly do it with your beloved Vortex!!! I have one synched to an EDP (using the Grob Cable) but instead of sunthing the tap tempo, i trigger the morph AB.. with wildly different settings on A and B patches I get that squarewave mod thing.. I tell ya thats from Glitchingtonville Arizona...
