feedback loop with behringer xenyx internal effects (machinedrum)

YouTube via 909techno
"picked up this very cheap (err... i mean inexpensive) mixer to test out.

running machindrum into it and the feeding the internal effects back onto them self. pitch shifting, delays, reverbs, flanges.

And yes, I know the Behringer is not the nicest mixer. I've got better - my whole pointing in buying this (big time sale!) was to check out the latest round of Behringer's and see how they are coming along. I've really not messed with it yet much to give a full impression."
