How do I use sidechain compression in Ableton Live 12?
Founder & CEO, Futureproof Music School
To set up sidechain compression in Ableton Live 12, start by loading the Compressor device on the track you want to duck (like a bassline or pad). Click the arrow in the Compressor's top-left corner to reveal the Sidechain section, then enable it and select 'External' as the source. Choose the track you want to trigger the compression (usually your kick drum) from the Audio From dropdown menu, and adjust the threshold, ratio, attack, and release to taste until you get that signature pumping effect.
Frequently Asked Questions
What's the best ratio setting for sidechain compression on bass and kicks?
Start with a 4:1 or 6:1 ratio for clean ducking that doesn't sound overly aggressive. If you want more dramatic pumping effects common in house and techno, push it to 8:1 or higher.
Should I use Ableton's Compressor or Glue Compressor for sidechaining?
Use the standard Compressor for precise control and faster attack times on individual tracks like bass. The Glue Compressor works better for subtle group sidechaining across multiple elements since it adds analog-style warmth.
How do I sidechain to a ghost kick instead of my actual kick drum?
Create a new MIDI track with a simple four-on-the-floor kick pattern, mute its output by setting the track's Audio To to 'Sends Only,' then use it as your sidechain source. This gives you complete control over the ducking rhythm without affecting your actual kick sound.
