FL Studio 20 is the most advanced version of Image Line's popular DAW to date, and brought full Mac support among many other updates and improvements. A legendarily flexible environment, it has long been capable of sidechaining its effects - and sidechain compression is one of the most creative and useful ways to take advantage of these capabilities. In this short video from the course FL Studio 301: Advanced Production Workflows, Rishabh Rajan shows you how to set it up.
Rishabh uses a practical example to demonstrate one of the most common uses of sidechained compression - making a track "duck" when a kick drum sounds. The kick is routed into the sidechain compressor applied to the pad track, meaning that when kick signal is received, the compressor pulls the pad track down, resulting in the classic "pumping" effect heard on so many electronic tracks. The same applies to bass tracks, another popular use for this routing technique.
You'll see that sidechaining is quick and easy to set up in FL Studio 20 thanks to its intuitive design, and the results sound great! Be sure to check out the full course for a complete guide to advanced production techniques in FL Studio 20.
