1. Lesson Overview

This intermediate Sampling lesson shows how to create a Ray Keith comb-filter bass: design and arrange in Ableton Live 12 for 90s-inspired darkness. You’ll sample or resample a Reese-style source, route it through an Ableton-based comb-filter effect chain (using stock devices), tune resonances, animate movement, and arrange the bass across a drop so it drives that sinister, late‑90s Drum & Bass vibe.

2. What You Will Build

  • A layered, sampled bass patch (sub + mid/texture) in Simpler.

  • A comb-filter effect implemented with Ableton’s Simple Delay (short‑ms delay + feedback) on a Return track to produce metallic resonances and notches like Ray Keith’s dark basses.
  • A processing/automation scheme (Saturator, EQ Eight, Compressor/Sidechain, Utility) and mapped Macros to morph the comb for arrangement and transitions.
  • A 16–32 bar loop demonstrating arrangement techniques that push the comb-filter into the mix for "dark" sections and pull it back for clarity.

    • 3. Step-by-Step Walkthrough

    Note: keep Ableton Live 12’s stock devices in use (Simpler, EQ Eight, Simple Delay, Saturator, Compressor, Utility, Glue/Compressor, Send/Return workflow).

    A. Prepare or create your sampled bass source

  • Option A (sample): Find a short Reese/dirty saw bass sample (1–2 seconds). Drag it into a MIDI track’s Simpler (Classic mode), enable Loop, trim start, set Transpose to match your key.
  • Option B (resample): Create a bass in Operator or Wavetable (sine sub + detuned saw), record 1–2 bars to an audio track (arm + record), crop one cycle or a looped phrase, then drag that audio into Simpler. Sampling your own sound gives more control.

    • Simpler settings:

  • Loop on, Loop Mode: Forward.
  • Filter: lowpass ~ 8–12 kHz for taming top end (we’ll add dirt later).
  • Amp ADSR: short attack, sustain 0.8–1, release ~100–200 ms for body.

    • B. Basic bass processing chain (on the bass track)

  • Insert Saturator (Drive 2–5 dB, Soft Clip), choose "Analog Clip" or medium curve.
  • Place EQ Eight after Saturator: Low cut at ~30 Hz (safety), gentle dip at 200–400 Hz if muddy, slight boost around 80–120 Hz for sub presence.
  • Add Compressor (optional) for glue or use Glue Compressor on group. Keep minimal attack to preserve transients.

    • C. Create the comb-filter return (this is the core)

  • Create a Return Track (R1) named "Comb".
  • On R1 insert Simple Delay (disable Sync — use ms). Key starting values:

    • - Left/Right Delay: 3.5 ms — 7.5 ms (try 3.2, 4.1, 6.8 ms; small adjustments change resonance pitches).

    - Feedback: 70% — 92% (higher feedback = stronger, more metallic resonances).

    - Dry/Wet: 100% — this return will be the delayed signal you sum with the dry bass.

    - Ping‑Pong off (keep mono stereo consistent to avoid phase weirdness), unless you want stereo movement (use slightly different L/R ms).

  • After Simple Delay add EQ Eight on the return:

    • - High cut around 6–8 kHz to avoid shrillness.

    - A narrow band boost (Q high) to emphasize a particular resonance if you want formant-like peaks (e.g., 300–800 Hz for vocal-ish metallic tone or 1–2 kHz for mid bite).

  • Add Saturator after EQ on return to add grit to the resonances (Drive minimal — 1–3 dB).
  • Optional: add Utility on the return and reduce Width to 60–80% or mono the low end with the main bass.

    • D. Routing and sound: summing dry + comb

  • On the bass track, raise Send A (to R1) to taste (start ~ -6 to -3 dB). The dry bass plays on the track; the delayed return mixes back in. The interference between dry and delayed copies produces comb filtering (notches & peaks).
  • Keep the return volume under the bass to avoid over-saturation of the mix. Use the channel fader on R1 to control the prominence.

    • E. Sculpting the character (automation & macros)

  • Macro 1: Map Simple Delay Time (ms) on R1. Automate/Map to change resonance pitch. Small changes (0.1–1 ms) move the spectral comb.
  • Macro 2: Map Simple Delay Feedback. Increasing feedback makes the comb harsher and longer.
  • Macro 3: Map EQ Eight narrow boost frequency on return to sweep a formant.
  • Macro 4: Map Send from bass to R1 (so a single turn brings the comb in).
  • For movement: automate delay time slowly over a section (16–32 bars) or create short clip automation for quick stabs (e.g., boost Send for 1/4 bar hits). Use clip envelopes for per‑bar stutter.

    • F. Layer sub + comb

  • Keep a pure sub (sine) underneath if your sampled source lacks low-end consistency. Create a second Simpler with a sine one‑shot, low pass to 150 Hz, and route through Utility > Mono below 120–150 Hz. Sidechain this sub to the kick for clarity.
  • The comb-return should be more audible in the mid/upper bass region; on R1, use EQ Eight to notch sub frequencies (<100 Hz) so the comb doesn’t cancel the sub.

    • G. Arranging for 90s-inspired darkness

  • Intro (bars 1–8): sub-only or muted comb (Send low) to build tension.
  • Pre-drop (bars 9–12): slowly open Macro 1 (delay time sweep) and increase Send to introduce metallic movement.
  • Drop/Heavy section (bars 13–20): send up, feedback high, narrow EQ boost to emphasize the “growl.” Use stuttered MIDI bass hits (shortened Simpler Release) with the comb engaged on offbeat hits to create ghosting and menace — Ray Keith often used sparse but heavily textured bass hits.
  • Breakdowns: automate the comb time to move slowly, or map the comb feedback to kick stabs to create rhythmic modulation.
  • Use resampling: freeze & flatten the section with comb engaged, then chop the resample to create aggressive stabs or looped dark textures.

    • H. Mixing touches

  • Use a compressor (sidechain) on the comb return keyed to kick to keep low-end clear.
  • Apply Utility on bass to mono below 150 Hz.
  • Use EQ Eight to clean overlapping resonances—if comb creates a peak around 500 Hz clash with vocals or hats, notch it narrowly.
  • Limiter on master is fine; avoid pushing feedback so much that the bus overloads.

    • 4. Common Mistakes

  • Feedback runaway: setting Simple Delay feedback too high (>95%) can self-oscillate. Keep an emergency limiter or lower feedback.
  • Too much wet return: making the return louder than the dry source removes punch and can collapse sub. Balance subtlety vs effect.
  • Ignoring phase/sub cancellation: combing can cancel sub frequencies if delay times create phase inversion. Always check mono and use a pure sub layer if needed.
  • Over-automating delay time dramatically: big jumps in ms cause clicks or pitch artifacts. Use small ms sweeps or resample and edit when big changes are needed.
  • Forgetting to filter the return: the comb builds harsh harmonics; without EQ or high-cut, the mix will be muddy or shrill.

    • 5. Pro Tips

  • Multi-return trick: create two Comb returns with slightly different delay times (e.g., 3.4 ms and 4.7 ms) and different EQ boosts to build a multi-formant Ray Keith style bass bank.
  • Resample your best comb riffs into one-shots and map them in Sampler for precise per-note control and easier arrangement.
  • Use short clip automation for the Send knob to create rhythmic bursts — much more CPU-friendly than automating device parameters all the time.
  • For live morphing, map Macros to an external controller and assign smoothing (in Macro Map) so delay changes feel organic.
  • To find resonant pitches quickly: switch Simple Delay to ms and, while playing a sustained note, nudge the ms value and listen for strong harmonic peaks; match those ms settings to musical notes by ear.
  • Save CPU: Freeze/Flatten the comb-heavy track, then re-import as audio to continue processing.

6. Mini Practice Exercise

Goal: Make a 16-bar loop where the comb-filtered bass rises into the drop.

Steps:

1. Create a 4-bar sampled bass loop in Simpler (looped sustain).

2. Add Saturator + EQ on the track, then create Return R1 with Simple Delay set to 4.1 ms, Feedback 82%, Dry/Wet 100%.

3. Send bass to R1 at -6 dB. Add a narrow boost at ~700 Hz on R1 EQ Eight.

4. Map Macro A to R1 Delay Time, Macro B to Feedback, Macro C to Send amount.

5. Arrangement:

- Bars 1–4: Macro C = 0 (comb off).

- Bars 5–8: slowly raise Macro A by +0.4 ms.

- Bars 9–12 (pre-drop): Macro C to -3 dB (comb present).

- Bars 13–16 (drop): Macro C to 0 dB, Macro B +6% (more feedback). Add staccato cuts on bars 14 & 15 (clip envelope shortening).

6. Export 16 bars and compare with a reference Ray Keith-era drop — focus on darkness (resonant mid-bass) and sub clarity.

7. Recap

This lesson taught how to create a Ray Keith comb-filter bass: design and arrange in Ableton Live 12 for 90s-inspired darkness using stock devices. Core ideas: sample or resample a Reese-like source in Simpler, build a comb using Simple Delay on a Return (short ms + high feedback), shape the resonances with EQ and Saturation, automate delay time/feedback/send for movement, and arrange the comb to come in during pre-drops/drops while preserving sub. Practice the small loop exercise, watch for phase & feedback pitfalls, and resample your best comb patches for aggressive 90s-style stabs.

Explain this lesson in a simpler way for a beginner.
Absolutely — here’s the lesson in a much simpler, beginner-friendly way. # The basic idea You’re making a **dark 90s-style DnB bass** by doing this: - start with a **simple bass sample** - keep a **clean sub** underneath - send the bass into a **very short delay** - blend that delayed signal back with the dry bass That short delay creates the **metallic, hollow, growling comb-filter sound**. Think of it like this: - **dry bass** = body and weight - **very short delayed copy** = dark texture and movement - **together** = Ray Keith-style menace --- # What “comb filter” means in plain English A comb filter happens when: - you hear the original sound - and a tiny delayed version of it at the same time Because the delay is so short, the two sounds **cancel and boost different frequencies**. That gives you: - hollow tone - metallic resonance - growl - moving “dark” texture In this lesson, we fake that using **Ableton’s Simple Delay**. --- # What you’re building You only really need 3 parts: 1. **Bass sound in Simpler** 2. **Sub layer** for clean low-end 3. **Comb Return track** using Simple Delay --- # Super simple setup ## 1) Make your main bass ### In Ableton: - Create a **MIDI track** - Drag in **Simpler** - Drop in a **Reese-style sample** or dirty bass sample - Turn **Loop** on - Use **Classic** mode ### Good beginner settings: - **Attack:** very short - **Sustain:** high - **Release:** around 100–200 ms - **Filter:** lowpass around 8–12 kHz This gives you a playable bass that can hold notes. --- ## 2) Add basic processing to the bass track After Simpler, add: ### Saturator - **Drive:** 2–5 dB - Turn on **Soft Clip** This adds dirt and weight. ### EQ Eight - Cut below **30 Hz** - If muddy, dip a bit around **200–400 Hz** That keeps it cleaner. --- ## 3) Make the comb filter on a Return track This is the key part. ### Create a Return track - Use an empty Return track - Rename it **Comb** ### On that Return, add: 1. **Simple Delay** 2. **EQ Eight** 3. **Saturator** 4. optional **Utility** --- # The important Simple Delay settings On the **Comb Return**: ### Simple Delay - Turn **Sync off** - Use **milliseconds** - Set delay time to around: - **4.1 ms** to start - Set **Feedback** to about: - **80–85%** - Set **Dry/Wet** to: - **100%** - Turn **Ping Pong off** Why? - the bass track already gives you the dry signal - the Return should only give you the delayed copy --- # Why this works When you send your bass to that Return: - the dry bass plays normally - the delayed copy comes back from the Return - the two combine - you hear the comb-filter tone So you’re not inserting the effect directly on the bass. You’re **blending it in with a send**, which gives you more control. --- # 4) Shape the comb Return ## EQ Eight on the Return Do this: - **High cut** around **6–8 kHz** - **Cut lows below 100–120 Hz** This is very important. Why? - you want the comb sound in the **midrange** - you do **not** want it messing up your sub You can also try: - a small narrow boost around **600–800 Hz** That often brings out the vocal/metallic growl. ## Saturator on the Return - add just a little drive - around **1–3 dB** This roughens up the resonances. --- # 5) Blend it in Go back to your bass track. Raise the **send** to the Comb Return. ### Start here: - Send amount around **-6 dB to -3 dB** Then listen. If it sounds: - **too subtle** → raise the send - **too harsh** → lower the send or feedback - **too thin** → the Return is too loud, or it has too much low-end --- # 6) Keep the sub clean This part matters a lot in Drum & Bass. The comb sound is cool, but the **sub should stay solid**. ## Easy beginner method: Make a second MIDI track for sub. ### On that sub track: - use **Simpler** or **Operator** - choose a **sine wave** - play the same bass notes - keep it simple and mono ### Add: - **EQ Eight** lowpass around **120–150 Hz** - **Utility** set narrow or mono Now you have: - **sub track** = clean low-end - **main bass track** = character - **comb Return** = dark texture That is a very solid dark DnB setup. --- # The main controls you should learn You only need to focus on 3 things at first: ## 1) Delay Time Example: - 3.5 ms - 4.1 ms - 5.0 ms Small changes make a big difference. This changes the **tone** of the comb. ## 2) Feedback Example: - 75% = lighter - 82% = stronger - 90% = aggressive This changes how intense and ringing it is. ## 3) Send Amount This controls **how much comb** you hear. This is the easiest thing to automate in arrangement. --- # A very easy beginner recipe If you want the fastest path, do exactly this: ## Bass track - Simpler with a dirty/Reese sample - Saturator: **Drive 3 dB** - EQ Eight: - low cut at **30 Hz** - small dip at **300 Hz** if muddy ## Comb Return - Simple Delay: - Sync **Off** - Time **4.1 ms** - Feedback **82%** - Dry/Wet **100%** - EQ Eight: - cut below **100 Hz** - high cut at **7 kHz** - small narrow boost at **700 Hz** - Saturator: - Drive **2 dB** ## Blend - Send from bass to Return: start at **-6 dB** That alone gets you into the right zone. --- # How to arrange it in a DnB track The lesson’s arrangement idea is simple: ## Intro - mostly **sub** - little or no comb ## Pre-drop - slowly raise the **send** - maybe slightly move the **delay time** This creates tension. ## Drop - more send - slightly more feedback - shorter, punchier bass notes That gives you the dark, aggressive hit. --- # Easy 16-bar arrangement example ## Bars 1–4 - bass dry - comb off or very low ## Bars 5–8 - slowly increase comb send ## Bars 9–12 - move delay from **4.1 ms to 4.4 ms** - keep send moderate ## Bars 13–16 - raise send more - raise feedback a little - make bass rhythm more staccato This makes the drop feel like it opens up and gets more sinister. --- # What to listen for You’re aiming for: - **clean sub** - **midrange growl** - **dark metallic movement** - **not too much top-end fizz** - **not too much mud** If the bass feels: - **cool but weak** → add or fix sub - **big but messy** → reduce return lows - **sharp and annoying** → high cut the Return more - **flat and boring** → automate send or delay time slightly --- # Common beginner mistakes ## 1) Too much feedback If feedback gets too high, the Return can scream or ring out too much. Stay around: - **75–90%** ## 2) Too much Return level If the comb Return is too loud, the bass loses punch. The effect should support the dry bass, not replace it. ## 3) Letting comb into the sub If the Return has low-end, it can cancel or blur the sub. Always cut lows on the Return. ## 4) Big delay-time jumps If you automate the delay time too wildly, it can click or sound broken. Use **small moves**. --- # Best beginner workflow If I were teaching this from scratch in Ableton, I’d tell you: ## Step 1 Get a bass loop working first. ## Step 2 Add the comb Return and make it sound good on one long note. ## Step 3 Blend in just enough for darkness. ## Step 4 Add a clean sub underneath. ## Step 5 Automate the **send amount** across 16 bars. That’s enough to learn the core idea. --- # If you want it darker For this Ray Keith / dark 90s vibe: - use **less bright top end** - use **more low-mid growl** - try delay times around **3–6 ms** - push a narrow EQ boost around **500–800 Hz** - use **short, sparse bass phrases** - leave space around the bass hits Dark DnB often feels heavier because it is **simple, threatening, and controlled**, not super busy. --- # Simplest possible version of the whole lesson ## One-sentence version: Make a bass, send it to a Return with a very short delay, blend that delayed copy back in, and automate how much you hear during the drop. ## 5-step version: 1. Put a Reese sample in **Simpler** 2. Add **Saturator + EQ Eight** 3. Make a **Return** with **Simple Delay at about 4 ms** 4. Send the bass to that Return 5. Keep sub clean and automate the send in the drop --- # Beginner checklist - [ ] Load dirty bass sample into **Simpler** - [ ] Turn **Loop** on - [ ] Add **Saturator** - [ ] Add **EQ Eight** on bass track - [ ] Create Return track called **Comb** - [ ] Add **Simple Delay** on Return - [ ] Set delay to about **4.1 ms** - [ ] Set feedback to about **82%** - [ ] Set Dry/Wet to **100%** - [ ] Cut lows below **100 Hz** on Return - [ ] High cut Return around **7 kHz** - [ ] Send bass to Return - [ ] Add separate **sine sub** - [ ] Keep sub mono and clean - [ ] Automate comb send in pre-drop and drop --- If you want, I can also turn this into a **super easy Ableton Live 12 step-by-step session build** you can follow exactly from an empty project.

Title: Ray Keith comb-filter bass — design and arrange in Ableton Live 12 for 90s-inspired darkness.

Welcome. In this intermediate Sampling lesson you’re going to build a Ray Keith–style comb-filter bass in Ableton Live 12. We’ll start from a Reese-style source, route it through a comb-filter effect chain built with Live’s stock devices, tune resonances, animate movement with macros and automation, and arrange a 16–32 bar loop that brings that late‑90s Drum & Bass darkness into the drop.

What you’ll end up with:
- A layered sampled bass patch in Simpler: a sub layer plus a mid/texture layer.
- A comb-filter implemented on a Return using Simple Delay with short milliseconds and high feedback to create metallic resonances and notches.
- A processing and automation scheme — Saturator, EQ Eight, Compression, Utility — with mapped Macros to morph the comb during arrangement.
- A short arranged loop where the comb is introduced for dark sections and pulled back for clarity.

Step-by-step walkthrough

A — Prepare or create your sampled bass source
You have two options. Option A: use a short Reese or dirty saw sample, one to two seconds long. Drag it into a MIDI track’s Simpler in Classic mode. Enable Loop, trim the start to taste, and transpose so the sample matches your key.

Option B: resample your own bass from Operator or Wavetable. Make a sine sub plus detuned saw, record a bar or two to an audio track, crop a cycle or a looped phrase, and drag that audio into Simpler. Sampling your own source gives you more control.

Simpler settings to start with:
- Loop on, Loop Mode forward.
- Lowpass filter around 8 to 12 kilohertz to tame top end — we’ll add dirt later.
- Amp ADSR: short attack, sustain around .8 to 1, release between 100 and 200 milliseconds for solid body.

B — Basic bass processing chain
On the bass track insert Saturator first. Drive around 2 to 5 dB with Soft Clip and choose a medium curve or Analog Clip setting. Follow Saturator with EQ Eight: a low cut at about 30 Hz for safety, a gentle dip between 200 and 400 Hz if it’s muddy, and a small boost around 80 to 120 Hz for sub presence. Add a Compressor or Glue Compressor if you want more glue, but keep attack moderate so transients remain.

C — Create the comb-filter return
Create a Return track and name it “Comb” or R1. On R1 insert Simple Delay and switch off Sync so you work in milliseconds. Start with short delay times in the range of roughly 3.5 to 7.5 ms — try values like 3.2, 4.1, or 6.8 ms; small changes move the resonance pitches. Set Feedback high, somewhere between 70 and 92 percent — higher feedback gives stronger metallic resonances. Dry/Wet should be 100 percent on the Return because you’ll be summing this delayed signal with the dry bass.

Keep Ping‑Pong off for a mono-consistent comb unless you deliberately want stereo movement. If you do, offset left and right ms slightly on a second return.

After Simple Delay, add EQ Eight on the return: high cut around 6 to 8 kHz to avoid shrillness, and a narrow band boost with a high Q to emphasize a resonance — anywhere from 300 to 800 Hz for vocal-ish metallic tone or 1 to 2 kHz for mid bite. Add a little Saturator after the EQ for grit — 1 to 3 dB drive. Optionally use Utility and reduce Width to 60–80 percent or mono the low end.

D — Routing and summing dry + comb
On the bass track, raise Send A to R1 to taste — start around -6 to -3 dB. The dry bass plays on the track and the delayed return mixes back in; their interference creates the comb filtering, producing notches and peaks. Keep the Return fader under the dry bass so the comb textures enhance rather than overpower.

E — Sculpting the character with automation and macros
Map and automate to make movement musical:
- Macro 1: map R1 Simple Delay Time (ms) to shift resonance pitch. Small changes of 0.1 to 1 ms produce musical movement.
- Macro 2: map Simple Delay Feedback to control comb harshness and decay.
- Macro 3: map the narrow EQ boost frequency on the return to sweep a formant.
- Macro 4: map the Send amount from the bass to R1 so one knob brings the comb in and out.

Use slow automation over 16 to 32 bars for evolving motion or short clip automation for quick stabs and stutters. Short Send bursts are CPU-friendly and tight for rhythmic ghosting.

F — Layer sub + comb
If your sampled source lacks consistent low end, add a dedicated sub. Make a second Simpler with a sine one‑shot, lowpass to ~150 Hz, Utility to mono it below 120–150 Hz, and sidechain it to the kick for clarity. On the comb Return, notch or cut everything below about 100 Hz so the comb doesn’t cancel or interfere with the sub.

G — Arranging for 90s-inspired darkness
A simple arrangement idea:
- Intro (bars 1–8): sub-only, comb send low to build tension.
- Pre-drop (bars 9–12): slowly open Macro 1 for a delay time sweep and increase the Send to introduce metallic movement.
- Drop/Heavy section (bars 13–20): Send up, feedback higher, narrow EQ boost to emphasize the “growl.” Use staccato, shortened bass hits with comb active on offbeat hits for ghosting and menace — sparse but textured, like Ray Keith’s style.
- Breakdowns: automate delay time slowly or tie comb feedback to kick stabs for rhythmic breathing.
Resample your best comb riffs, then chop them into stabs and re-use them for aggressive textures.

H — Mixing touches
Sidechain the comb return to the kick to keep low-end clarity. Use Utility to mono below 150 Hz on the bass. Use EQ Eight to clean overlapping resonances — notch narrowly where the comb clashes with other elements. Put a limiter on the master if needed, and don’t push feedback so far that the bus overloads.

Common mistakes to watch for
- Feedback runaway: feedback above ~95 percent can self-oscillate. Keep a limiter or cap feedback with Macro mapping.
- Too much wet return: if the return is louder than the dry source you’ll lose punch and sub presence.
- Phase and sub cancellation: combs can cancel sub frequencies if delay times create phase inversion. Always check in mono and use a dedicated sub layer if needed.
- Dramatic ms jumps: big changes in delay time can create clicks and pitch artifacts. Use small sweeps or resample then edit audio when you need big shifts.
- Forgetting to filter the return: the comb builds harsh harmonics — use EQ and gentle Saturation on the return to control shrillness.

Pro tips and practical math
- Quick conversion: approximate resonant frequency in hertz ≈ 1000 divided by delay_ms. So 4.0 ms → ~250 Hz, 3.3 ms → ~303 Hz, 2.0 ms → 500 Hz. Use that to find where the comb will emphasize or notch relative to your root note.
- Multi-return trick: create two Comb returns with slightly different ms values and different EQ boosts to build multi-formant banks for a classic Ray Keith complexity.
- Resample your best comb riffs into one-shots and map them in Sampler for per-note control and easier arrangement.
- For performance morphing, map Macros to a hardware controller and set safe min/max ranges to avoid runaway feedback.
- Macro mapping: limit delay ms to a narrow range (for example ±0.8 ms) and set feedback max to around 92 percent. Steeper macro curves near the top let you go from subtle to aggressive quickly.

Mini practice exercise — make a 16-bar loop
1. Create a 4-bar sampled bass loop in Simpler with looped sustain.
2. Add Saturator and EQ on the track. Create Return R1, Simple Delay at 4.1 ms, Feedback 82 percent, Dry/Wet 100 percent.
3. Send bass to R1 at -6 dB. Add a narrow boost at about 700 Hz on R1’s EQ Eight.
4. Map Macro A to R1 Delay Time, Macro B to Feedback, Macro C to Send amount.
5. Arrange:
   - Bars 1–4: Macro C = 0, comb off.
   - Bars 5–8: slowly raise Macro A by about +0.4 ms.
   - Bars 9–12: Macro C to about -3 dB to introduce comb.
   - Bars 13–16: Macro C to 0 dB, Macro B +6 percent for more feedback. Add staccato cuts on bars 14 and 15 with clip envelope shortening.
6. Export and compare the result to a Ray Keith-era reference, listening for dark resonant mid-bass and clean sub.

Recap
You’ve learned to build a Ray Keith comb-filter bass in Ableton Live 12 using stock devices: sample or resample a Reese-like source in Simpler, create the comb on a Return with Simple Delay set to short ms and high feedback, shape resonances with EQ and Saturator, automate delay time, feedback and send for movement, and arrange the comb to accent pre-drops and drops while protecting the sub. Practice the 16-bar loop, watch for phase and feedback pitfalls, and resample your best sounds into one-shots for classic 90s control.

Final coaching note
Be intentional with the comb: small, well-placed movements and controlled feedback are what make this effect musical. Find ms settings that line up with your bass harmonics, keep the sub pure and stable, and resample your best moments into tight one-shots to capture that classic Ray Keith darkness.
