The side-chain input on EXS24 and ES2 is strictly for modulation purposes.

These include the EXS24 sampler the ES1, ES2, and Sculpture synths and the EVOC PS polysynth-vocoder. Let's start with a look at the Logic instrument plug-ins that support side-chains. The drop-down menu under the Side Chain label allows you to select any Logic track, input, or buss as the source of the side-chain signal (as pictured above). When a side-chain input is available it is located at the right-hand end of the gray strip at the top of the plug-in's control panel.

With a synthesizer, on the other hand, Logic 's side-chain inputs are often used to process audio using the synth's filters and effects.Ī number of Logic and Audio Units plug-ins offer side-chain inputs. For example, feeding a separate audio track to a compressor side-chain allows you to create ducking effects. Side-chain audio is often used for some control purpose. So what can you do with them?Ī side-chain is an auxiliary audio input to a synthesizer or effects processor. Side-chains are usually associated with effects processing, but they are also available in many of Logic 's internal soft synths.

To assign any signal in Logic's mixer to a plug-in's side-chain, click on the Side Chain button which appears at the top of every suitable plug-in to access a drop-down menu.
