The Glue Compressor in Logic: the closest equivalents
Updated July 2026
Ableton's Glue Compressor is a Cytomic-built model of the classic SSL 4000-series (G-series) bus compressor — the console unit that gave "glue" its name. Logic Pro has no device called Glue, but it has the same hardware modelled: the stock Compressor's Vintage VCA circuit type is Logic's SSL-style bus VCA, and it does the same job on a drum bus or mix bus. In other words, the answer is one menu click, not a plugin purchase. This guide translates each Glue control to its Logic counterpart, gives you a bus-glue recipe to start from, and is honest about the few things that don't carry across.
What you're actually replacing
The Glue is deliberately simple — nine controls, and every one earns its place. Threshold sets where compression starts. Ratio is stepped to three positions — 2:1, 4:1 and 10:1 — like a switch on the hardware. Attack is stepped too, from 0.01 up to 30 ms, and Release runs 0.1–1.2 s plus an Auto position that follows the programme. Makeup restores the level you took away. Then the three that make it feel modern: Range caps the maximum gain reduction the compressor is allowed to apply, Soft Clip rounds off peaks at the output, and Dry/Wet blends for parallel compression without building a rack.
The character matters more than the feature list. Used as intended — slow attack, Auto release, and only 1–3 dB of gain reduction — the Glue makes the whole bus rise and settle together, a slow breathing that turns eight drum tracks into one instrument. That behaviour comes from the bus-VCA design it models, which is exactly why the equivalent in Logic is a specific circuit type, not just any compressor with similar knobs.
Logic's Compressor is seven compressors
Logic's stock Compressor hides the answer behind one control. Its circuit-type menu switches the plugin between seven distinct models: Platinum Digital (the clean, uncoloured one), Studio VCA, Studio FET, Classic VCA, Vintage VCA, Vintage FET and Vintage Opto. Same knobs on the outside, different knee, timing and colour inside each one.
The one you want for Glue duties is Vintage VCA — Logic's SSL-G-flavoured bus VCA, the same family of hardware Cytomic modelled for Ableton. Select it first, before touching a knob, because the circuit type changes how every other control responds. And skip the urge to audition all seven on the drum bus "just to be sure": the others are good compressors for other jobs, but only Vintage VCA is this compressor.
Control-by-control translation
- Threshold → Threshold. Same job. Don't copy the printed number across, though — the two plugins scale and meter differently, so match by watching gain reduction, not knob positions.
- Ratio (stepped) → Ratio (continuous). The Glue snaps to 2:1, 4:1 or 10:1; Logic's ratio sweeps freely. For glue work, set 2:1 and treat it like a switch you don't touch again.
- Attack (stepped) → Attack (continuous). On the Glue you were probably parked at the slow end of its 0.01–30 ms range. In Logic dial 10–30 ms so transients pass before the compressor grabs — the fast settings are for taming a source, not gluing a bus.
- Release / Auto → Release + Auto Release. The Glue's Auto position is half its magic; Logic has the same idea as an Auto Release switch. Turn it on and let the release track the material instead of holding one fixed time.
- Makeup → Gain. Logic also offers Auto Gain; for bus glue, leave the automatics off and set makeup by hand — an auto-boosted signal always wins the A/B for the wrong reason.
- Dry/Wet → Mix. Logic's Compressor has a Mix control, so the Glue's built-in parallel-compression trick survives: compress harder than tasteful, then blend it under the dry signal.
- Soft Clip → the Distortion stage. Logic's Compressor ends in an output Distortion section with Soft, Hard and Clip modes. Used gently, Soft does the Glue's Soft Clip job of shaving peaks; pushed hard, it's an effect in both plugins.
- Range → nothing. The honest gap. Range caps how many dB of gain reduction the Glue may apply, and Logic's Compressor has no such ceiling. Translate the intent instead: back off the threshold and keep the ratio at 2:1 until the loudest section can't drive the meter past the reduction you would have capped.
One thing Logic adds rather than lacks: the Compressor's side-chain filter section can high-pass the detector so kick and bass stop pumping the whole bus — the fix Glue users rig with a sidechain-EQ trick in a rack is a built-in filter here.
A bus-glue recipe to start from
- Insert Logic's Compressor on the bus, set the circuit type to Vintage VCA and the ratio to 2:1.
- Set attack around 10–30 ms — slow enough that drum transients punch through before the clamp closes. If the bus loses its snap, slow the attack further before you touch anything else.
- Switch Auto Release on. Bus glue wants the release breathing with the arrangement, not holding a number.
- Pull the threshold down until the loudest sections show 1–2 dB of gain reduction, with the meter returning to zero in the gaps. If you're seeing 4–6 dB, it's a compressor now, not glue.
- Set makeup gain by ear and bypass-compare at equal loudness. If the processed bus only wins because it's louder, it hasn't won yet.
What won't translate
Three things, honestly. First, the fine print of the models differs: the Glue is Cytomic's rendering of the circuit and Vintage VCA is Apple's, so the knee, the exact release curves and the behaviour when pushed hard won't null against each other. At the gentle 1–2 dB this job calls for they're close relatives; at 8 dB of reduction they're different characters, and you should re-decide by ear. Second, the Range workflow: if you built habits around setting the Glue deep and letting Range enforce restraint, that safety net doesn't exist in Logic — the restraint has to move back into the threshold and ratio. Third, muscle memory: stepped attack and ratio switches made Glue settings repeatable by feel. Logic's continuous knobs land wherever you leave them, so save the setting that works as a preset instead of trusting your hands.
Moving a whole Ableton project?
If the Glue sits on the drum bus of a Live set you're taking to Logic, you don't have to rebuild the session around it by hand. Doseedo converts the .als into a native Logic .logicx: tracks arrive in order with names and colors; audio clips keep their fades and clip gain; MIDI notes, CC and pitch bend come across; tempo and time-signature maps, markers, volume, pan and breakpoint automation lanes, and buses and sends all carry over. On plugins, the honest picture: stock compressor, reverb, and delay settings map to the destination DAW's native devices with their core controls intact; other plugins arrive placed on the right track as device slots to re-fill — third-party preset state isn't reconstructed. The Glue is the happy case here: it is a stock compressor, so its threshold, ratio, attack, release and makeup land on Logic's native Compressor, on the right bus — set the circuit type to Vintage VCA, confirm by ear, and you're back where you left off. The full spec is on the what-carries-over breakdown.

FAQ
Does Logic Pro have the Glue Compressor?
No — the Glue Compressor is Ableton's device, built by Cytomic, and it ships only with Live. But Logic's stock Compressor models the same SSL-style bus hardware: set its circuit type to Vintage VCA and you have Logic's version of the same idea, with threshold, ratio, attack, release, makeup and a Mix control to match.
Which Logic compressor is best for bus glue?
The stock Compressor with the circuit type set to Vintage VCA. Start at a 2:1 ratio, a slow 10–30 ms attack and Auto Release on, then pull the threshold until the loudest sections show 1–2 dB of gain reduction and match the makeup gain by ear so the bypass comparison is at equal loudness.
Do Glue Compressor settings transfer when I convert a project?
Yes — the Glue is a stock compressor, so Doseedo maps its settings — threshold, ratio, attack, release, makeup — onto Logic's native Compressor with those core controls intact. Treat the circuit-type character as a starting point to re-check by ear: confirm Vintage VCA is selected and A/B the bus before you call it done.
Is there a Range knob in Logic's Compressor?
No. The Glue's Range caps the maximum gain reduction; Logic's Compressor has no equivalent cap. Translate the intent instead: ease the threshold and keep the ratio low so the loudest sections can't push the meter past the reduction you would have capped — for glue duties that usually means 1–2 dB.
