Creating a Sidechain Effect for Synthesizers in Reaper Daw

by

Creating a sidechain effect for synthesizers in Reaper DAW is a popular technique used to make your sounds more dynamic and punchy. This effect is commonly used in electronic music to create a “pumping” sound, especially when mixing basslines with kick drums. In this guide, you’ll learn how to set up a sidechain compression for your synthesizer in Reaper.

What is Sidechaining?

Sidechaining is a process where the output of one track (like a kick drum) controls the compression of another track (such as a synthesizer). When the kick hits, it temporarily reduces the volume of the synth, creating a rhythmic pulsing effect. This technique helps to clear space in the mix and adds energy to the track.

Steps to Create a Sidechain Effect in Reaper

  • Insert a Compressor on your Synth Track: First, select your synth track and add Reaper’s built-in compressor or any third-party compressor that supports sidechain input.
  • Enable Sidechain Input: In the compressor settings, find the sidechain or “key input” option and enable it.
  • Set the Kick Drum as the Sidechain Source: Choose your kick drum track as the input source for the sidechain. This links the kick to control the compressor on the synth track.
  • Adjust Compression Settings: Tweak the threshold, ratio, attack, and release to achieve the desired pumping effect. A lower threshold and higher ratio will produce a more pronounced effect.
  • Test and Fine-tune: Play your project and listen. Adjust the compressor settings until the sidechain effect sounds natural and fits your mix.

Additional Tips

  • Use a dedicated sidechain bus if you want to control multiple tracks with the same source.
  • Experiment with different attack and release times to match the rhythm of your track.
  • Combine sidechaining with EQ to emphasize certain frequencies during the pumping effect.
  • Try different compressor plugins to find the character that best fits your style.

By following these steps, you can add professional-sounding sidechain effects to your synthesizers in Reaper, enhancing the groove and clarity of your mixes. Practice and experimentation are key to mastering this powerful technique.
