Welcome. In this lesson we’ll build a Breakage-style comb-filter bass from scratch in Ableton Live 12, using Session View to perform and then capture into Arrangement View. You’ll design a two-layer bass, create a delay-based comb-filter effect, build an effect Rack with expressive macros, perform multiple variations in Session, and record that performance into Arrangement to create a tight, evolving edit.
Lesson overview first: keep a small Drum & Bass loop running at about 170 to 176 BPM so you hear the bass in context. Name your tracks so you don’t lose them. The goal is a chunky sub plus a harmonically rich mid layer, a comb-filter chain using a short delay and feedback, and an Audio Effect Rack mapped to macros for live control. We’ll make Session clips—full, filtered, stuttered, and peak-comb variations—and record those live into Arrangement to form a Breakage-style edit.
What you will build:
- A two-layer bass patch: a clean sub and a harmonically rich mid layer in Wavetable or Operator.
- A delay-based comb-filter chain, available as an insert or as a parallel send-return.
- An Audio Effect Rack with macros for comb intensity, delay time, feedback, and cutoff.
- A set of Session clips and scenes that you can launch and capture into Arrangement.
Step-by-step walkthrough.
A — Create the bass source.
Create a new MIDI track and load Wavetable or Operator.
- For the sub layer: use a sine or low-band-limited waveform. In Wavetable choose basic sine partials or a simple sine oscillator. Drop one oscillator an octave, keep the filter off, set a fast amp attack, medium decay, and a slight sustain for fullness.
- For the mid layer: use a richer wavetable—Basic Shapes saw with a light wavetable position works well—or a noisy table. Add subtle FM or filter modulation for harmonics, a little detune, and a lowpass filter in the 2 to 5 kHz range with some drive.
You can place these on separate MIDI tracks or use one Instrument Rack with two chains: Sub and Mid. Map chain volume and a low cut on the mid chain to macros for quick control.
B — Tighten and glue for DnB.
On the mid chain add a light Saturator—Soft Sine or Analog Clip—with 2 to 5 dB of drive to taste. Follow with an EQ Eight:
- High-pass the mids around 30 to 40 Hz if the sub is separate.
- Optionally boost a narrow band around 200 to 700 Hz for presence.
- Cut any nasty resonances.
Add a Glue Compressor as the last insert: roughly 4:1 ratio, medium attack, fast release to glue the mids. Sidechain from the kick if you need the bass to duck during hits.
C — Make the comb-filter effect using delay.
Ableton doesn’t have a dedicated comb device, but you can create comb resonances with a very short delay plus feedback. We’ll build a flexible Audio Effect Rack.
Create an Audio Effect Rack on the bass track, or on a return for parallel control. Inside the rack create two chains:
- Chain A: Dry chain with a Utility for level control.
- Chain B: Comb chain with Simple Delay (or Echo), then EQ Eight, then Saturator. You can also use an Auto Filter after the delay for musical sweeps.
Configure Simple Delay for comb behavior:
- Turn Sync off and work in milliseconds.
- Set delay time to a short value: start between 2 and 12 ms. Try 3.5 ms for brighter combs, 6 to 12 ms for thicker low combs.
- Feedback around 60 to 85 percent gives strong resonances; be careful—feedback can run away.
- Set the device Dry/Wet to 100% on this chain and control balance via chain volumes or macros.
EQ the comb chain to shape resonant peaks. High-pass under 40 Hz to protect the sub and use narrow boosts where you want the comb peaks to sit. Optionally add Auto Filter for cutoff sweeps after the delay.
Map the rack macros:
- Macro 1: Chain B volume — “Comb Intensity.”
- Macro 2: Simple Delay Time — “Comb Pitch / Shift.”
- Macro 3: Simple Delay Feedback — “Comb Feedback.”
- Macro 4: EQ or Auto Filter cutoff — “Comb Filter Cutoff.”
D — Create performance variations in Session View.
Duplicate your bass track so you can experiment without losing the original. On Track A create a 1–4 bar looped MIDI clip with your bassline and name it “Bass — Full.”
Create more clips under that clip:
- “Bass — Filtered”: automate Macro 4 down and raise Macro 1 slightly to emphasize comb energy while dulling the highs.
- “Bass — Stutter”: create a MIDI clip with repeated short notes or apply the clip volume envelope for 1/16 gating to get a stutter.
- “Bass — Peak Comb”: set Macro 3 high and nudge Macro 2 for a different comb resonance emphasis.
- “Bass — Sparse”: shorten notes and reduce comb intensity.
Use clip envelopes to record parameter moves per clip. In the Clip view under Envelopes, pick the Audio Effect Parameter or the Macro and draw the automation you want recalled when that clip launches.
E — Performance and capturing into Arrangement.
Organize your scenes vertically: Intro (sparse), Build (rising comb and mids), Drop (full bass), Breakdown (filtered and stutter), then Return.
Practice launching scenes in time. You can use Follow Actions for quick automated variations. When you’re ready to record to Arrangement, enable Arrangement Record, then use the Session record button and launch your scenes and clips in real time. Live will record audio or MIDI and automation into Arrangement View.
If you prefer, you can drag Session clips to Arrangement to copy clip content, but remember that clip automation is only preserved if it was recorded into the clip or you actually recorded the performance into Arrangement.
During recording perform macro moves—comb intensity, delay time sweeps, cutoff changes—and capture scene transitions and stutters. After recording, switch to Arrangement View, tidy clip edges, and consolidate (Cmd/Ctrl+J) to clean things up. Edit automation lanes to smooth or quantize macro moves as needed.
F — Finalize: bounce and glue.
In Arrangement, solo the bass region and render in place or freeze and flatten to print the comb effect as audio—this is useful for resampling stutters or reducing CPU. Add a final EQ or low-shelf and use Utility to mono the sub below about 120 Hz. If you need to shape transients, use a transient shaper or a fast-attack compressor.
Common mistakes to avoid.
- Too much feedback: high feedback settings cause runaway resonance and masking. Watch levels.
- Using sync instead of ms: short, synced delay times won’t create useful comb behavior—use milliseconds.
- Forgetting to protect the sub: HP the comb chain under 30–45 Hz or keep the sub layer dry.
- Not routing for parallel control: placing the comb only as an insert makes low-end control harder.
- Over-automation clutter: don’t record every minor knob move. Plan major moves and keep clips tidy.
- Ignoring phase: duplicating bass layers can produce cancellations. Check phase and adjust timing or use Utility to invert phase if needed.
Pro tips.
- Comb time relates to perceived pitch: spacing in hertz is roughly 1000 divided by delay milliseconds. Use that to pick delay times that sit musically.
- Try two parallel comb chains with slightly different ms values, mapped to different macros for richer motion.
- Resample favorite performances as audio to slice and stutter without heavy CPU use.
- Smooth automation with Bezier curves or a finer grid when needed.
- Use transient sidechain on the comb chain from the kick to keep hits tight.
- Save your Audio Effect Rack as a preset with clear macro labels and mapping ranges.
Quick parameter ranges to start with.
- Comb Delay Time: 2.0 to 12.0 ms. Map Macro 2 min to 2 ms and max to 12 ms.
- Feedback: 50 to 80 percent for strong combs; use a limiter if you push past 75 percent.
- HP on comb chain: 30 to 45 Hz.
- Keep the comb chain device Wet at 100 percent and use chain volume or macro for wet/dry balance.
Troubleshooting short fixes.
- Harsh metallic ringing: reduce feedback, cut the offending frequency with a narrow EQ, or slightly detune the delay time.
- Phase cancellation thinning: invert phase on one chain or nudge timing by a few samples.
- Automation not recorded: enable Automation Arm and use Arrangement Record while performing.
- Runaway feedback: map a macro to an emergency kill or to the chain volume so you can mute instantly.
Mini practice exercise — 30 minutes.
1. At 174 BPM make a 2-bar Wavetable bass loop.
2. Build the comb Audio Effect Rack with Simple Delay and map four macros: Intensity, Time, Feedback, Cutoff.
3. Make three Session clips: Full, Filtered Sweep (automate Macro 4 down over two bars), and Stutter (1/16 gating).
4. Launch the three clips in sequence while arm-recording Arrangement. Perform a Macro 2 sweep during the second clip for a pitch-y comb sweep.
5. Stop recording. In Arrangement trim and consolidate into a 6-bar edit, then render that region to audio and compare the printed audio to your live performance.
Recap.
You’ve created a Breakage-style comb-filter bass by designing a two-layer source, making a delay-based comb Audio Effect Rack, mapping expressive macros, and using Session View to perform variations which you captured into Arrangement. Key takeaways: short ms delays with feedback create comb resonances; parallel routing and HP filtering protect the low end; macro mapping plus Session performance is a fast, musical workflow for edits; and printing or resampling your performance makes aggressive edits and stutters reliable and CPU-light.
That’s it. Save the Rack as “Comb Bass Rack — Breakage Edit,” keep your macro mapping notes, and use this template next time you want to make fast, expressive comb edits in Live 12.
