1. Lesson overview

Energetic, controlled send/return routing is one of the single biggest tools to glue a drum & bass track together while keeping the low end tight and the top end huge. In this intermediate lesson we’ll build a practical send/return workflow in Ableton Live tailored for rolling DnB / jungle — you’ll learn how to create multiple purpose returns (long ambience, short snare reverb, rhythmic echo, parallel crunch, and parallel compression), how to set them up with the right device chains and settings, and how to use them musically in arrangement and automation. Expect concrete device chains (using stock devices), exact workflow suggestions, and arrangement ideas for drops, fills, and breakdowns. 🎚️🔥

Software: Ableton Live (Live 10/11 recommended — Live 11 gives you Hybrid Reverb & Echo, but I’ll give fallbacks).

Tempo/culture: This tutorial assumes 170–175 BPM (classic DnB). Adjust delay sync values if you use other tempos.

2. What you will build

  • A set of 4–5 return tracks optimized for DnB:

    • - Return A: Long ambient reverb for pads/atmospheres

    - Return B: Short gated/plate reverb tailored for snares and percussion

    - Return C: Rhythmic echo/delay for breaks and rolling groove

    - Return D: Parallel distortion/saturation (grit for mid/high drums and midbass)

    - Return E: Parallel compressor for fattening drums (glue/compress)

  • A workflow: how to route groups (drum bus, percussion, snare, bass) to these returns, recommended send levels, pre/post usage, sidechain/ducking patterns, and automation strategies for arrangement (builds, drops, fills).
  • Device chains and specific starting parameter suggestions using Ableton stock devices (Hybrid Reverb / Reverb, Echo / Delay, EQ Eight, Compressor / Glue, Saturator / Overdrive / Redux, Utility, Beat Repeat).

    • 3. Step-by-step walkthrough

    Follow these numbered steps in Ableton Live. I'll assume you have a simple DnB template with a Drum Rack / break, a snare channel, a drum bus, a bass channel, and some pads.

    Setup basics

    1. Set project tempo to 174 BPM.

    2. Open the Return Tracks (View → Return Tracks if hidden). Create 5 returns (A–E).

    3. Rename them and color-code:

    - A: Long Reverb (blue)

    - B: Short Snare Reverb (pink)

    - C: Rhythmic Echo (green)

    - D: Parallel Distortion (orange)

    - E: Parallel Compression (red)

    Important mixing principle: keep returns at 100% Wet (their device wet/dry = 100%) where possible; control effect amount with the send knobs on source tracks. This keeps one place to control the wet/dry balance and avoids double-dipping.

    Return A — Long Ambient Reverb (pads, tails)

    1. Device chain (preferred Live 11): Hybrid Reverb → EQ Eight (HP filter) → Utility.

    - Hybrid Reverb settings: Mode = 100% Reverb, Size/Decay ~ 2.0–3.0 s (start 2.4 s), Pre-Delay 10–20 ms (12 ms), Diffusion moderate (20–40%), Damping/hf rolloff to taste.

    - Set Hybrid Reverb Wet = 100% (we will control amount with send knobs).

    2. EQ Eight after reverb:

    - Create a high-pass (shelf) at ~120–200 Hz (24 dB/oct) to avoid muddying subs.

    - Optionally switch EQ Eight to M/S mode (click the little “M/S” or right-click mode) and reduce the side-channel low frequencies below ~350 Hz by -6 to -12 dB so the reverb stays centered in the low end.

    3. Utility: Width ~ 40–60% (keeps low end tighter). Return fader start ~ -6 dB.

    Use: Send pads, atmos, and upper bass harmonics (see bass routing below) lightly. For breakdowns send more to create space.

    Return B — Short Snare/Drum Reverb (tight, snappy)

    1. Device chain: Reverb (or Hybrid Reverb short algorithm) → Gate (optional) → EQ Eight → Compressor (ducking).

    - Reverb settings: Decay 0.4–0.9 s, Pre-Delay 8–15 ms (tightens hit), Size small-to-medium. Diffusion high for short smear.

    - Set Dry/Wet = 100% on the return.

    2. EQ Eight: HP filter ~200–300 Hz (24 dB/oct). Tilt off low end.

    3. Compressor: Light sidechain setup (see below) or put the Compressor last to duck the reverb when the main snare/kick hits.

    4. Return fader start ~ -9 dB.

    Use: Send your snare and rim hits here. For jungle/swinging snare, use moderate send (send knob -10 to -7 dB). For snares in big breaks increase send to taste. For gated reverb: after Reverb put a Gate and set threshold to catch tail only — great for 90s-style gated snare hits in tunes.

    Return C — Rhythmic Echo (groove & fills)

    1. Device chain: Echo (Live 11) or Delay (Live 10) → Filter (Auto Filter / EQ Eight) → Utility.

    - Echo settings (174 BPM): Sync ON, choose note value 1/16 or 1/8T (try 1/16 dotted for rolling grooves), Feedback 20–45% for subtle repeats or up to 60% for rhythmic loops, modulation depth small for movement, Diffusion low if you want clearer echoes.

    - Delay/Sync values idea:

    - For 174 BPM, 1/16 = tight repeats for break chopping; 1/8T (triplet) = classic DnB swing.

    - Dry/Wet = 100% on return.

    2. Filter: Low-pass ~6–10 kHz, high-pass 200–300 Hz (so repeats are mid/high focused).

    3. Utility: Width reduced for low-mid to keep mono-ish or to create wide echoes for fills.

    4. Return fader start ~ -8 dB.

    Use: Send breakbeat hats, percussion, high toms, certain snare flams. Automate send during fills for rhythmic motion.

    Return D — Parallel Distortion / Grit (adds bite to midrange)

    1. Device chain: Saturator (or Overdrive) → EQ Eight → Redux (optional for bit crushing) → Utility.

    - Saturator: Type = Analog Clip or Tube. Drive start +6–10 dB. Soft Clip on. Output trim to unity.

    - EQ Eight: Low cut around 120 Hz. Boost mid-range frequencies lightly 800 Hz–2 kHz +2–4 dB if you want more presence.

    - Redux: bit reduction low amount (optional) for grime — keep subtle.

    2. Keep the chain Wet = 100% (use it as a parallel grit bus).

    3. Return fader start ~ -10 dB.

    Use: Route the Drum Bus or percussion to this return for aggressive midrange energy. For midbass, send only the mid/harmonic layer (not sub). Great on breaks to make snare top-end snap.

    Return E — Parallel Compression Glue (fat drums)

    1. Device chain: Compressor (or Glue Compressor) -> Saturator (optional) -> Limiter (optional).

    - Compressor: High ratio (6:1 to 10:1), Attack 1–5 ms, Release 50–150 ms (adjust to taste). Push 6–12 dB gain reduction for heavy parallel compression.

    - Put Gain/Make-up to bring level back.

    2. Send your Drum Bus to E. Keep the return wet 100%.

    3. Blend return under the dry track; typical send is subtle: -12 to -6 dB (or visually 20–40% send knob). Adjust for punch.

    Use: This adds body and sustain without flattening the transient attack from the dry drums.

    Routing and bass considerations (critical for DnB)

    1. Never send sub (below ~100 Hz) to wet long reverb returns. Sub tails = mud and phase problems.

    2. Two approaches to keep sub dry and still use reverb/echo on the higher bass content:

    - Frequency split on the bass: Duplicate the bass channel. On duplicate insert EQ Eight high-pass at ~120–150 Hz. Send the duplicate to Return A/C for atmosphere/echo. Keep the original dry with no sends.

    - Or use a Multiband approach inside the return: put an EQ Eight in the return set to M/S and cut side/bass below 120–150 Hz, or use an audio effect rack splitting by frequency sends (create chains with filters).

    3. Make low-end reverb mono: on the return add an EQ Eight in M/S mode and cut the sides under about 300–350 Hz, or use Utility with Width=0% on a low band.

    Sidechaining reverb/delay (to keep the low end punchy)

    1. Put a Compressor (or Glue) on the return with Sidechain enabled.

    2. Choose Kick+Snare Bus as the sidechain input and set the threshold to duck the reverb on hits (attack ~1–5 ms, release 80–200 ms for natural duck).

    3. This lets the transients cut through but keeps tails audible between hits.

    Pre-fader vs Post-fader sends (when to use)

    1. Default: leave sends post-fader (so volume automation affects send level).

    2. For performance/looper ideas or when you want consistent effect level regardless of track fader automation (e.g., a break loop whose dry volume changes but you want constant wet), right-click the send knob and select “Pre” to make the send pre-fader. Use sparingly.

    3. For DnB: mostly post-fader — when drop goes silent you usually want the reverb to die with it.

    Arrangement ideas and automation

    1. Drops: cut or drastically reduce reverb sends for drums and bass during the first hit of a drop. Automate returns or individual send knobs to “kill” ambience for large impact.

    2. Fills: automate a snare send spike to Return C (Echo) or throw more to Return D (grit) on a 1 bar fill.

    3. Build-ups: slowly increase send to Return A (Long Reverb) on atmos/pads; open feedback on Echo for more repeats as a transition.

    4. Breakdowns: raise Return E (parallel compression) and Return A a bit for extra sustain and space.

    5. Use return device automation (decay time, feedback amount) to build tension — e.g., increase Echo feedback and low-pass frequency sweep on the last bar of a build before the drop. This is more CPU-friendly than automating a plugin per-source.

    Useful Ableton device shortcuts and tricks

  • Set Wet/Dry = 100% on returns; control with sends.
  • Right-click send knob → “Pre” to change to pre-fader send.
  • Use EQ Eight in M/S mode to keep low-end mono (mode selectable in the device header).
  • Use Freeze/Flatten on a return track to freeze complex effect tails for CPU savings and to resample unique textures.
  • Put Utility at the end of returns for widening or monoing low end.

    • Practical start values (a reference you can tweak)

  • Long Reverb: Decay 2.4 s, Pre-Delay 12 ms, HP @ 120 Hz on return.
  • Short Reverb: Decay 0.6 s, Pre-Delay 10 ms, HP @ 220 Hz.
  • Echo: Sync 1/16 dotted or 1/16, Feedback 30–45%, Low-pass ~8 kHz, HP ~250 Hz.
  • Parallel Distortion: Saturator Drive +8 dB, Soft Clip ON, LP/HP to taste.
  • Parallel Comp: Ratio 8:1, Attack 2 ms, Release 90 ms, aim 6–12 dB GR (heavy).

    • 4. Common mistakes

  • Sending the sub bass to long reverb (creates mud and phase problems). Always HP the signal you send or split frequency.
  • Using return device Dry/Wet < 100% — now you control wet from two places. Put Wet = 100% and control with sends/return fader.
  • Too much reverb/echo in a dense section — leads to wash and loss of definition. Use automation and sidechaining.
  • Forgetting to mono low end of returns — stereo reverb on subs ruins translation to clubs.
  • Not grouping before sending — routing drums individually to various returns can get messy. Use Drum Bus / Perc Bus and send from group level when appropriate.
  • Overuse of pre-fader sends — can create confusing automated levels that don’t follow track dynamics.
  • Not using different returns for different timescales (short vs long). One big reverb for everything equals one-dimensional soundscape.

    • 5. Pro tips for darker/heavier DnB

  • Parallel Distortion for midrange weight: route percussion + midbass harmonics to Return D. Crush with Saturator -> Overdrive -> EQ (HP at 120 Hz), then lowpass back some highs. Blend subtly for aggression without destroying punch.
  • Use extreme sidechain on returns for claustrophobic drops: put a Glue or Compressor on Reverb and Echo returns sidechained to the kick/snare with quick release so tails breathe between hits but get slammed when hits land.
  • Lo-fi grit on fills: Put Beat Repeat on a return (Interval 1/16, Grid 1/32, Chance 30–50%, Gate off for stutters). Automate Chance up for a one-bar chaotic breakdown.
  • Use Erosion + Redux on a dedicated “salt & grit” return to add texture to breaks — keep the low-end filtered out.
  • Automate reverb damping / decay to shorten the tail right before a heavy drop (reduces masking) then snap it back on for the breakdown.
  • For a darker stereo image, automate return Utility width (reduce width slightly in main sections, open width in breakdowns for atmosphere).
  • Create a bespoke “sub-reflection” return: a micro short reverb (predelay 1–6ms, decay 40–80 ms) with an M/S EQ boosting a little low-mid to give bass a more “room” without adding long tails.

    • 6. Mini practice exercise

    Goal: Build 3 returns and use them on a basic DnB loop (4 bar loop: kick, tangent snare, roll break, bass stab, pad).

    Steps:

    1. Load a 4-bar drum loop (or program a simple kick + programmed break). Have a separate snare track and bass track.

    2. Create Return A (Long Reverb) and put Reverb / Hybrid Reverb. Set Decay = 2.4 s, Pre-Delay = 12 ms, Wet = 100%. Put EQ Eight after it and HP @ 120 Hz.

    3. Create Return C (Echo): add Echo, Sync 1/16, Feedback 35%, Wet = 100%. Add Auto Filter after with HP = 200 Hz and LP = 8 kHz.

    4. Create Return E (Parallel Comp): add Compressor, Ratio 8:1, Attack 2 ms, Release 90 ms. Push it to get 6–10 dB gain reduction.

    5. On the Drum Bus: send 25–35% to E, 10–20% to C, 6–12% to A. On the Snare track: send 30–40% to B (create B as a short reverb similar to Step 2 but decay 0.5 s).

    6. For bass: duplicate the bass track. On duplicate, high-pass at ~130 Hz. Send the duplicate 10–20% to A and 8–15% to C. Keep original dry with no sends.

    7. Play and adjust sends so the mix stays punchy. Then:

    - Automate the send knob to Return C on the snare: create a 1-bar automation spike during the fill.

    - Automate Return A fader: raise it by 3–4 dB over the breakdown bars.

    - Put a Compressor on Return A sidechained to Drum Bus with short release to get tails to duck on hits.

    Result: You’ll hear how long ambience creates space for pads, Echo adds rhythmic repetition and movement for breaks, and parallel compression glues the drums while preserving transient attack.

    7. Recap

  • Use multiple returns for different roles: long ambience, short hits, rhythmic delay, parallel grit, and parallel compression. This lets you shape space and grit without muddying your low end.
  • Always filter the returns (HP to remove subs), and use EQ Eight in M/S mode to keep low-end mono.
  • Put Wet = 100% on returns and control effect amounts from send knobs; use return fader for global wet level.
  • Sidechain and duck returns to keep hits punchy; automate send amounts and return parameters for transitions.
  • For DnB: split bass frequencies (duplicate + HP copy) so tails and echoes don’t destroy the sub foundation.
  • Use Ableton stock devices: Hybrid Reverb / Reverb, Echo / Delay, EQ Eight (M/S), Compressor/Glue, Saturator/Overdrive, Beat Repeat for creative fills.

Go build a few return templates with these chains and save them as a Template Set — you’ll thank yourself when you’re in the middle of a session and need big, tight-sounding DnB in minutes.

Hey — welcome. This is an intermediate Ableton lesson all about send and return workflow for drum and bass, focused on keeping the low end tight while making the top end feel huge. I’m going to walk you through a practical setup you can build in Live 10 or 11, give you concrete device chains and starting parameters, explain routing and automation strategies for drops and fills, and share pro tips and common mistakes so you don’t waste time troubleshooting later. Let’s get into it.

First, the big picture. Use multiple dedicated returns for different roles: long ambience for pads, a short snare reverb, a rhythmic echo for groove and fills, a parallel distortion bus for grit, and a parallel compressor to glue drums. Always set the effects on the returns to 100 percent wet and control the amount with the send knobs on the source tracks. That keeps one place responsible for the wet/dry mix and prevents accidental double-dipping.

Start by setting your project tempo to 174 BPM. Open the Return Tracks and create five returns. I’ll refer to them as Return A through E. Rename and color them so they’re instantly recognizable — for example, Return A Long Reverb, Return B Short Snare Reverb, Return C Rhythmic Echo, Return D Parallel Distortion, and Return E Parallel Compression.

Return A is Long Ambient Reverb for pads and atmos. If you have Live 11, use Hybrid Reverb. In Live 10 use Reverb and push decay. Set decay around 2.4 seconds to start, pre-delay about 12 milliseconds, diffusion moderate, and damp the highs to taste. Put an EQ Eight after the reverb and high-pass around 120 to 200 Hz, and consider using EQ Eight in M/S mode to cut the sides under ~350 Hz so your reverb doesn’t smear the low end. Add a Utility at the end with width around 40 to 60 percent. Set the return fader around minus six dB as a starting point.

Return B is the Short Snare Reverb — tight and snappy. Chain Reverb or Hybrid’s short algorithm, set decay between 0.4 and 0.9 seconds, pre-delay 8 to 15 ms, and Wet at 100 percent. After the reverb put a Gate if you want gated tails, then EQ Eight with a high-pass around 200 to 300 Hz, and a light Compressor last that you’ll use for ducking. Start this return around minus nine dB. Send snares and rims here at moderate levels — think around minus ten to minus seven dB on the send knob — and increase for big breaks.

Return C is your Rhythmic Echo. In Live 11 use Echo, in Live 10 use Delay. Sync on. For 174 BPM try 1/16 or 1/8 triplet for rolling grooves. Feedback is a useful parameter: 20 to 45 percent for subtle repeats, up to 60 percent for more looped rhythms. Put a filter after the delay — Auto Filter or EQ Eight — high-pass around 200 to 300 Hz and low-pass around 6 to 10 kHz so the repeats live in the mid/high band. Return fader start around minus eight dB. Automate sends to this for fills and rolling percussion movement.

Return D is Parallel Distortion for midrange bite. Chain Saturator or Overdrive, then EQ Eight to cut below around 120 Hz and boost presence around 800 Hz to 2 kHz by a couple of dB if needed. Optionally add Redux for subtle bit reduction. Drive around plus six to plus ten dB with soft clip on and trim output to unity. Set the return fader around minus ten dB. This is where you route drum bus or percussion to add aggression — but avoid sending subs. Send only the mids and harmonic content.

Return E is Parallel Compression for glue. Use Compressor or Glue with a high ratio like eight to ten to one, very fast attack around one to five milliseconds and release around 50 to 150 ms. Push it to get six to twelve dB of gain reduction and use make-up gain to bring level back. Keep this return Wet at 100 percent and blend under your dry drums — typical send amounts are subtle: think minus twelve to minus six dB, or visually 20 to 40 percent on the send knob.

Routing and bass considerations are critical in DnB. Never send sub below roughly 100 or 120 Hz to long reverb or echo. Two practical approaches: duplicate your bass track and high-pass the duplicate around 120 to 150 Hz, then send the duplicate to returns while keeping the original dry for sub energy. Or split frequencies inside a return using EQ Eight in M/S or an effect rack to keep subs out of the wet signal. Always make low end mono on returns — use Utility width or EQ Eight in M/S to collapse sides under 300 to 350 Hz.

Sidechaining returns keeps the low end punchy. Put a compressor on the return and sidechain it to your kick and snare bus. Fast attack like one to five ms and release around 80 to 200 ms usually sounds natural and lets tails breathe between hits. This is especially helpful on long reverb and echo returns so the transients cut through.

A quick word on pre-fader versus post-fader sends: leave sends post-fader most of the time so send levels follow track fader automation. Switch a send to pre only when you need the effect level independent of the track fader — for example, a live loop you want a constant echo on while you control dry level separately.

Now a few automation and arrangement strategies. For drops, kill or drastically reduce reverb sends for drums and bass on the first hit to make the drop hit harder. For fills, spike the snare send to the rhythmic echo or crank the distortion return for one-bar aggression. During builds, slowly raise long reverb on pads and open echo feedback; automate reverb decay or echo feedback on returns for tension rather than automating every source — it’s simpler and more CPU friendly. Treat returns as arrangement elements: create 1 to 2 bar automation lanes on return faders and trigger them like instruments.

Common mistakes to avoid: sending pure sub to long reverb, leaving return effects at less than 100 percent wet, overusing pre-fader sends, and forgetting to mono the low end. Also group tracks before sending where it makes sense — send from a drum bus rather than individually routing every drum unless you truly need that granularity.

Pro tips for darker, heavier DnB: use parallel distortion on midbass harmonics and percussion, employ extreme sidechain on returns for claustrophobic drops, and use Beat Repeat or Grain Delay on dedicated returns to create chaotic fills. If CPU becomes an issue, freeze and flatten a return or resample a stacked effect to audio.

A short practice exercise to put this into action: build three returns — Long Reverb, Echo, and Parallel Comp. Set Long Reverb decay around 2.4 seconds, pre-delay 12 ms, with HP at 120 Hz. Set Echo to 1/16 synced with 35 percent feedback and HP at 200 Hz. Make the parallel comp heavy enough for 6 to 10 dB GR. On your drum bus send roughly 25 to 35 percent to the parallel comp, 10 to 20 percent to echo, and small amount to the long reverb. Duplicate your bass, HP the copy at 130 Hz and send that copy to the reverb and echo while keeping the original dry. Automate a 1-bar spike to the echo send on a fill and raise the long reverb fader in a breakdown. Add a sidechain compressor to the long reverb keyed to the drum bus.

Some extra coach notes: solo-test returns by soloing the return track while the source plays and using Solo-In-Place to hear how the effect sits against the dry. Keep return faders near unity during setup and control gain with device outputs. Map Utility width to a macro for quick mono-checks and use Freeze/Flatten or resampling to manage CPU if chains get heavy. Organize returns with clear names and small text hints so collaborators know recommended send levels.

For homework, build a 32-bar section with an intro, build, drop, and breakdown, using at least three returns and resample one transition tail into a playable sample. Make sure no significant reverb energy sits under 100 Hz, transients stay punchy, and your resampled tail triggers cleanly at the drop.

Recap: use multiple focused returns, set wet to 100 percent, filter and mono low end, sidechain and automate returns for musical transitions, split bass frequencies to protect the subs, and save your return templates so you can recall them instantly. If you want, I can generate a concise checklist you can paste into your project or provide a .als outline with the exact device chains and starting parameters to drop into a template.
