The Boomerang scratch is basically a continuous Aquaman. The trick is to leave the fader open at the end of the forward and reverse record movements. This turns the scratch into a 2 click pattern, starting from fader closed, over continuous babies.

The Autobahn scratch uses a similar record movement to the Aquaman/Boomerang but creates more notes by placing clicks in the middle of the sample rather than on the ends. Start with the fader closed and perform a slice to 1 click forward. Then on the pull back do another click but end with the fader closed - similar to a flare. Makes 6 notes total.
