Sidechaining and ducking are techniques that can be used to seperate two elements in a track that clash for frequency space. For example a kick drum and a bassline when played together at the same time, can fight for space within the mix. Sidechaining is a tool that can be used to elminate this clashing of frequencies.
Sidechaining is often added to a tune in the form of a compressor. With FL Studio you can create your own simple sidechain by following these steps.
1. Open up a kick drum and a 3xOsc.
2. Send the kick drum to effects channel 1 and the 3xOsc to effects channel 2. If you don’t know how to add effects to channels then read How to Add Effects in FL Studio.
3. Open up the mixer by pressing F9. On effects channel 1 add an instance of the Fruity Peak Controller. Now set the peak controller to roughly the same settings as in the picture below (make sure that the “mute” button to the bottom right is turned off).
4. In the mixer window go to channel two and right click on the volume slider. In the menu that appears select Link to Controller.
5. In the menu that appears, go to the Internal Controller section and hit the down arrow. Select Peak ctrl (Insert 1) – Peak. That’s it! Now hit play and you should be hearing the 3xOsc duck everytime the Kick drum triggers!
To make a sidechaining compressor just put a compressor on mixer channel 2, and link the gain knob to the Fruity Peak Controller. The Peak Controller will duck the gain knob whenever the Kick drum is triggered. This technique can be used with any combination of instruments to create new and unusual sound effects. Enjoy!
