The Auto Pan device included with Ableton is a very simple device but can be applied in various ways to achieve initially unexpected results.
The Auto Pan is used initially to demonstrate ways to add stereo width and movement to a synth part . The same technique can also be employed when working with pad sounds.
The second demonstration involves creating a rack containing several Auto Pan’s acting as tremelos in order to pump a sine wave and create a rhythmic, pulsating bass line. The sound is then pushed through the dynamic tube device to add harmonics to the loudest parts of the signal.
The next Ableton Live tutorial will cover the Beat Repeat effect.
