How to Sidechain in Ableton (Step by Step for Beginners)
By Omar Meho, 4 November 2026
Sidechaining is the reason dance music pumps. It is also the quickest way to stop your kick and bass fighting each other. Once you learn it in Ableton you will use it on nearly every track, so here is how to do it properly.
What sidechain compression actually does
Normally a compressor reacts to the sound on its own track. With sidechain, it listens to a different track instead. Put a compressor on your bass, tell it to listen to the kick, and every time the kick hits, the bass ducks out of the way. The result is a cleaner low end and that classic pumping feel.
How to set up sidechain in Ableton
- Add a Compressor to the track you want to duck, for example your bass or pad.
- Open the sidechain section by clicking the small triangle at the top left of the Compressor.
- Switch Sidechain on, then in the Audio From menu choose your kick track.
- Set the ratio high, around 4:1 or more for an obvious pump.
- Pull the threshold down until you see the gain reduction meter moving on every kick.
- Set the attack fast, close to 0 ms, so the duck happens right on the kick.
- Adjust the release until the bass swells back in time with the groove.
Release is the setting that makes or breaks it. Too short and the bass clicks back in harshly. Too long and it never fully recovers before the next kick. Play the track and move the release slowly until it breathes with the tempo.
How much sidechain should you use?
It depends on the genre. In house and tech house you often want a noticeable pump on pads and bass. In techno it is usually subtler, just enough to keep the low end tidy. Watch the gain reduction meter. A few dB of reduction is a gentle clean up, while 8 dB or more is the obvious, pumping sound.
The best test is to switch the Compressor off and on while the track plays. If you can't hear any difference, push it further. If the bass sounds like it is gasping for air, back it off.
The ghost kick trick
Sometimes you want the pump to keep going when the kick drops out, like in a breakdown. That is where a ghost kick helps.
- Create a new track with a short kick playing on every beat.
- Set its Audio To output to Sends Only so you can't hear it.
- Point your sidechain Compressor at this ghost kick track instead of the real kick.
Now the ducking stays consistent all the way through the track, whatever your real drums are doing.
Other ways to sidechain in Ableton
The Compressor is the classic method, but it is not the only one.
- Glue Compressor has a sidechain section too and gives a smoother, more musical pump.
- Auto Filter can be sidechained, so the filter reacts to the kick instead of the volume.
- Gate with sidechain lets one sound open and close another, great for rhythmic pads.
- Volume shaping with an LFO or envelope device gives you a perfectly repeatable duck without a trigger track.
Common sidechain mistakes
- Sidechaining everything to the kick. Pick the sounds that clash: bass, pads and big chords. Leave hats and vocals alone unless you want an effect.
- Forgetting the threshold. If the threshold is above the kick level, nothing happens, even with sidechain switched on.
- Using a kick with a long tail. A boomy kick triggers a long duck. A shorter ghost kick gives you more control.
- Judging it solo. Always set sidechain with the full mix playing, because that is how people will hear it.
Sidechain is one of the first things I show new producers because it instantly makes a loop sound more professional. Pair it with a good bassline (my guide on how to write a house bassline will help) and your low end will feel tight and controlled.
Try it on your current project now. Set it up once, save the Compressor as a preset, and you will have it ready for every track you make from here on.
