Auto Pan as a chopper effect and more, from Liveschool. You've probably used Auto Pan for stereo effects in Ableton Live, but did you know that it can also be used for chopping effects and even cutting between two tracks? In this tutorial, Certified Trainer and Liveschool Instructor Adam Maggs shows you how to make the most out of Auto Pan. The Autopan Modulator is an effects processor designed to work around the stereo field of any given audio source. It can be programmed to make your tracks bounce from side to side of the audio field with several modulation options at your choice. If anyway you want to keep it simple, it will allow you to do so manually.
