Compression plug-ins for electronic music production
The question Which compressor plug-in should I use for electronic music production?
Short answer
You probably don't need to buy a compressor to start. Logic users already have Compressor, with seven circuit types and a side-chain section, and anyone can add the free DC1A for quick, characterful compression.
Buy when you can name the job. The Glue is a focused bus compressor with a side-chain high-pass, Range and Mix controls. FabFilter Pro-C 3 covers every job on this page and can be triggered by MIDI or the host tempo as well as by a kick track.
This guide compares documented features. We have not run listening tests, so it does not rank how the compressors sound.
Know which job you are buying for
Editorial In electronic music, "compression" covers several different intentions. The right compressor depends on which one you mean, and most producers need more than one of these.
Editorial
- Dynamic control: evening out a bassline or vocal so it sits at a consistent level. Precise attack and release, and a side chain that ignores the low end, matter most.
- Bus glue: gentle compression across drums or a full mix so separate elements move together. Console-style bus compressors are the classic tool.
- Side-chain pumping: ducking pads or bass from the kick, for clarity or as an audible rhythmic effect. You need a side-chain input, and MIDI or tempo-synced triggering is a bonus.
- Character: using a compressor's saturation and behaviour as a colour, sometimes with heavy gain reduction or in parallel.
Do you need to buy one?
Editorial Probably not at first. A host compressor with a side chain covers dynamic control and kick-triggered ducking, and a free character compressor covers the rest. Buying makes sense when one of these is true:
Editorial
- You spend most of your compression time on drum and mix buses and want a tool designed for that. Look at The Glue.
- You want rhythmic ducking without routing a kick, for example during a breakdown where the kick is muted. Look at FabFilter Pro-C 3, which documents MIDI and tempo triggering.
- You keep fighting low end that over-triggers your compressor and want precise side-chain EQ. Pro-C 3 documents up to six side-chain EQ bands.
- Your host has no compressor with a side chain.[1][2]
The options
If you already use Logic Pro
CompressorApple
Logic's Compressor offers seven circuit types, from the clean Platinum Digital to VCA, FET and Opto models, plus a dedicated side-chain section. That covers dynamic control, bus compression and side-chain ducking without leaving the host.
Switching circuit types on the same material is also a free way to learn how compressor designs differ before paying for one.
Worth knowing
- It is only available inside Logic Pro and MainStage, so the time you spend learning it doesn't carry over if you change DAW.
From the manufacturer's documentation
- Selectable circuit types: Platinum Digital, Studio VCA, Studio FET, Classic VCA, Vintage VCA, Vintage FET and Vintage Opto.
- Threshold, Ratio, Knee, Attack, Release and Auto Release controls.
- Auto Gain options of Off, 0 dB and -12 dB.
Free, fast character compression
DC1AKlanghelm
DC1A reduces compression to input and output controls, with switches for Deep (a high-pass to reduce pumping on bass-heavy material), Relaxed (peak or RMS behaviour) and Dual Mono. Klanghelm also lists a Mix control and describes parallel (New York style) use. It is free.
It suits producers who want quick, musical gain reduction without setting attack, release and ratio by hand.
Worth knowing
- Its simplicity is also its limit: there are no attack, release or ratio controls to fine-tune.
- Neither the product page nor the manual lists an external side-chain input, so it is not a tool for kick-triggered ducking.
- Klanghelm doesn't state minimum OS versions or Apple Silicon support; see the product record.
From the manufacturer's documentation
- Two main controls: input and output.
- Deep switch engages a high-pass filter to reduce pumping on bass-heavy material.
- Relaxed switch toggles between peak and RMS behaviour.
- Dual Mono mode compresses left and right channels independently.
Dedicated bus compressor
The GlueCytomic
The Glue is modelled on the classic 1980s British large-console bus compressor, the design most associated with gluing drum and mix buses. Cytomic documents a Range control that caps the maximum gain change, a soft side-chain high-pass filter so the low end doesn't over-trigger it, a phase-accurate Mix control for parallel compression, external side-chain support and a Peak Clip option.
If bus compression is the main job you are buying for, this is the most focused tool here.
Worth knowing
- It is one compressor design. You will still want something else for transparent dynamic control.
- It is paid; Cytomic offers a trial. Oversampling can be turned off for zero latency.
From the manufacturer's documentation
- Modelled on the classic 1980s British big-console bus compressor.
- Range control that limits the maximum amount of gain change.
- Mix control that crossfades the dry and compressed signals in a phase-accurate way.
- External side-chain support.
Most flexible all-rounder
FabFilter Pro-C 3FabFilter
Pro-C 3 offers fourteen compression styles, from transparent to vintage and upward compression, so it can cover every job on this page. FabFilter describes its Bus style as suited to bus glue and its Pumping style as "great for drum processing or EDM".
Its side chain takes up to six EQ bands with mid/side targeting, and it can be triggered from an external side chain, from MIDI or from a host-tempo-synced pulse with sync, offset and pulse-length settings. That last option creates rhythmic ducking without routing a kick track at all.
Worth knowing
- It is a paid product with the most options to learn; FabFilter offers a 30-day trial.
- Lookahead (up to 20 ms) adds latency. The maximum can be lowered, or left off when you play live through it.
From the manufacturer's documentation
- Fourteen compression styles in three groups. Modern: Clean, Versatile, Smooth, Punch, Upward and TTM. Classic: Op-El, Vari-Mu, Classic and Opto. Utility: Vocal, Mastering, Bus and Pumping.
- The Pumping style is described by FabFilter as 'deep and over-the-top pumping, great for drum processing or EDM'.
- The Bus style is described as especially suited to bus processing, adding glue to drums, mixes or tracks.
- Character modes: Off, Tube, Diode and Bright.
- Side-chain EQ with up to six bands, including all-pass and brickwall shapes, with mid/side targeting.

Electronic music scenarios
These examples show how each compressor's documented features could be applied. They describe a method, not a result, and settings depend on your material.
How to choose
Editorial
- Start with your host's compressor. Logic's has seven circuit types and a side chain.
- Add DC1A for quick, free character and parallel compression.
- Buy The Glue if your priority is drum and mix-bus glue.
- Buy FabFilter Pro-C 3 if you want one compressor for every job, especially side-chain work triggered by MIDI or tempo.
- Whichever you consider, use the trial on a current project and check it solves a problem you could not solve with what you have.[3][5][1][2]
Questions
- What is side-chain compression in electronic music?
- A compressor on one sound (often a pad or bass) is triggered by another (usually the kick), so the first sound ducks each time the trigger plays. Some compressors, including FabFilter Pro-C 3, can also be triggered by MIDI or a tempo-synced pulse instead of audio.[2]
- Is a free compressor good enough?
- For most jobs, yes. Your host's compressor and DC1A cover dynamic control and character. Paid compressors mostly add flexibility (side-chain EQ, more styles) or a specific design, such as the console bus model in The Glue.[5][1]
- Why does my compressor pump on bass-heavy material, and how do I stop it?
- Low frequencies carry the most energy, so they drive the detector. A high-pass in the side chain reduces this: DC1A has a Deep switch, The Glue a built-in side-chain high-pass, and Pro-C 3 a side-chain EQ with up to six bands.[5][1][2]
- Do I need lookahead?
- Only if a compressor is missing the very start of fast transients. Pro-C 3 offers up to 20 ms of lookahead, which adds latency, so leave it off when you play live through the plug-in.[2]
