Dub Techno Track

Deconstruction of an archetypal 8-minute dub techno track — the chord/delay feedback system, the soft kick, the hiss bed, every element as a Live 12 recipe, and a 10-step rebuild.

The blueprint: 122 BPM, 8 minutes, 240 bars, A minor, in the spirit of the Basic Channel / Chain Reaction / Echocord lineage. Dub techno is not a drum track with chords on it — it is a delay feedback system with a kick keeping time underneath. Three decisions make it work: (1) the chord stab and its delay are one instrument, performed live via feedback and filter automation, and the dry stab is often quieter than its echoes; (2) the whole mix sits inside a constant bed of hiss and vinyl noise that glues every element into one surface; (3) the kick is soft and long, almost a sub pulse, so the chord’s low-mid warmth at 150–400 Hz is never fighting a knock. Nothing has a hard edge. Movement comes from feedback, not from new notes.

BPM
122 (one bar = 1967 ms, 1/4 = 492 ms, dotted 1/8 = 369 ms, 3/16 = 369 ms, 1/16 = 123 ms)
Key
A minor — kick and sub on A0 (55 Hz), chord voiced Am9 around A2–B3
Length
240 bars ≈ 7:52
Mood
Submerged, warm, foggy. A long slow tide. The peak is when the delay almost runs away.
Stereo image
Kick, sub and hiss centre. Chord dry at 70% width, chord delays hard-panned with offset times. Ride and shaker ±40%.

Arrangement

240 bars with no drop and no silence. The track is a single long arc: hiss first, then kick, then chord echoes before the chord itself, then percussion arriving one piece every 16 bars. The centre section (96–160) is the "swell": chord delay feedback pushed to 80–90% in 16-bar waves, each wave pulled back just before self-oscillation. The release (160–208) removes the percussion but leaves the chord and delays running, and the outro is 32 bars of kick + hiss + fading echoes — long enough for a DJ to mix out of.

Energy curve. Dub techno energy is measured in density, not loudness. The hiss bed sets a floor from bar 0 so the kick entry at 16 feels like it is surfacing from something rather than starting. Chord echoes arrive at 48 before the dry chord at 64 — the listener hears a filtered, reverberated memory of a chord for 16 bars and then the chord itself lands as a confirmation. Percussion is one voice every 16 bars: shaker 40, rim 56, closed hat 72, ride 96. By the swell the drum kit is complete and the delay feedback does the rest. The release strips percussion in reverse, leaving the chord with the dry signal filtered darker each 16 bars, and the outro is a long exhale.

Transitions. No risers, no snare rolls, no silence. Every 16 bars one of: the Echo feedback nudged up 10% for 2 bars then back, the chord LP cutoff opened a half octave for a bar, or a 2-bar reverb swell (the chord sent 100% into a 12 s Hybrid Reverb with the dry muted). At 95–96 and 159–160 the reverb swell is the whole transition.

Frequency layering

The structural idea is that the chord is wide in the dry signal (110–500 Hz, warm) but its delays live in a narrower, higher band (300–1800 Hz). Because the Echo’s filter sits inside the feedback loop, each repeat loses low end and high end — the fifth echo is a 600–1200 Hz band-passed ghost. That is why 90% feedback does not become mud: the loop is self-cleaning. The kick is a long soft sine that overlaps the chord’s bottom (110–160 Hz) only when the chord sustains, and a gentle sidechain handles that. The percussion is sparse enough to each own a band: rim 1.2–3.5 kHz, shaker 3–8 kHz, hat 4–10 kHz, ride wide but 6 dB under the hat. Nothing is bright: the mix has a natural roll-off from 8 kHz, and the hiss bed supplies "air" instead of any element having it.

Element by element

The chord — Analog Am9 stab, pulse waves, filtered dark

Instrument: Analog · Level: intermediate · Genres: dub techno, deep techno

One voicing for the entire track: Am9 as A2-E3-G3-B3 (root, 5th, b7, 9th — no 3rd, the ambiguity is the point). Analog with two pulse-wave oscillators, slow PWM, a 12 dB low-pass at 700 Hz, short decay. It is a dull thud of a chord on its own; the delay makes it sing.

  1. Analog: Osc 1 Pulse, pulse width 40%. Osc 2 Pulse, −12 st, Detune +5 cents, pulse width 60%. Osc mix 50/50. Noise off.
  2. LFO 1 triangle 0.15 Hz → both oscillators’ pulse width, 20%. This slow PWM is the "breathing" inside every chord.
  3. Filter 1 LP 12 dB/oct, cutoff 700 Hz, resonance 20%, Filter env amount +25%, env A 0, D 300 ms, S 0. Amp env A 3 ms, D 450 ms, S 0, R 350 ms. Set Quick Routing to one filter / one amp (both oscillators through Filter 1).
  4. Chorus-Ensemble Vibrato mode, rate 0.5 Hz, amount 15% — a pitch wobble, not a widening.
  5. Saturator Soft Sine Drive 3 dB. EQ Eight HP 100 Hz, LP 3.5 kHz.
  6. Velocity 110 for and-of-2 hits, 70 for the beat-1 hit in bar 2. Note length 1/8.
Pulse waves with slow PWM produce a shifting comb of harmonics — the chord timbre changes on each hit even though the notes and the filter do not. The ear perceives "life" without any new musical information, which is the entire aesthetic.
Record 8 bars of the chord with its sends into a new audio track, then run it back through the same Echo. Stacked re-dubbing is how the classic records got echoes that have their own echoes.

The delay system — Echo in the feedback loop, filter and feedback as the performance

Device: Echo, Roar, EQ Eight · Level: advanced · Genres: dub techno, dub reggae

This is the track’s lead instrument. Echo on a return, dotted-eighth left and quarter right, filter inside the loop, soft saturation inside the loop, and the Feedback and HP/LP parameters mapped to Push encoders. Everything the listener hears as "the chord" after bar 96 is this return.

  1. Echo: Sync on, Left 3/16, Right 1/4, Stereo link off (that mismatch is the stereo movement), Ping-pong off, Feedback 60% as the resting state. Dry/Wet 100%.
  2. Filter section on, inside the loop: HP 300 Hz, LP 1.8 kHz, resonance low. Every repeat gets narrower — this is what makes 90% feedback usable.
  3. Modulation: rate 0.3 Hz, Delay mod 20% (pitch drift on the repeats), Filter mod 10%. Character: Wobble 15%, Noise 10%, Reverb 25%, Duck 30%.
  4. After Echo: Roar Single, Soft Sine, Drive 4 dB, post-filter LP 2.5 kHz. Then EQ Eight with a −3 dB dip at 350 Hz so stacked repeats do not pile up at the chord’s fundamental.
  5. Map Feedback (50–95%) and LP cutoff (800 Hz–4 kHz) to two Push encoders. The swell section is performed: four 16-bar waves to 70, 80, 85, 90%, each pulled back to 55% over the last 2 bars.
  6. Chord track: sends pre-fader so you can pull the dry chord to −inf (bars 48–64) and still feed the Echo.
At 90% feedback with 25% internal reverb the loop will self-oscillate within 8 bars. That is the sound — but ride it. Keep a Limiter (ceiling −3 dB) at the end of the return as a safety and automate rather than hoping.
Delay feedback with a band-pass in the loop converges on a resonant drone at the filter’s centre. Pushing toward that point and pulling back is the tension-release mechanism of the whole genre — it replaces the drop.

Kick — soft long sine, 909-low-tom character, barely any transient

Instrument: Operator · Level: beginner · Genres: dub techno

Deep, round, almost a pulse. Operator sine on A0 with a small pitch envelope, a 550 ms decay, and a Drum Buss for weight. The transient is softened on purpose so the chord’s low-mids have the front edge.

  1. Operator, Osc A sine only, A0. Pitch envelope +14 st, Decay 45 ms. Amp A 1 ms, D 550 ms, S 0, R 60 ms.
  2. Drum Buss: Drive 15%, Crunch 0, Boom 30% with frequency at 55 Hz (= A0), Transients −20%, Damp 8 kHz.
  3. EQ Eight: HP 32 Hz, bell −3 dB at 250 Hz Q 1.2 (clears the chord’s root), LP 1.5 kHz.

Sub — Drift half-notes on A0, sidechained, 2nd-harmonic only

Instrument: Drift · Level: beginner · Genres: dub techno, deep techno

A sine on A0 holding for half a bar on beats 1 and 3. It overlaps the kick and relies on the sidechain to make room. Its job is to make the kick feel like it has a floor, not to be heard as a separate note.

  1. Drift Osc 1 sine, Mono, Glide 0. Amp A 20 ms, D 0, S 1, R 150 ms. Filter MS2 LP 110 Hz.
  2. Compressor external sidechain from the kick, 5:1, 6 dB GR, Attack 0.3 ms, Release 110 ms — the release is tuned so the sub returns fully just before beat 2.

Bass pulse — Operator FM blip on the offbeat, dub-reggae phrasing

Instrument: Operator · Level: intermediate · Genres: dub techno, dub reggae

A short, slightly hollow bass note at 60–160 Hz on the and-of-1 and the and-of-3 — the dub-reggae skank moved into the bass. Operator with light FM for a woody attack.

  1. Operator algorithm B→A. Osc A sine, Osc B sine Coarse 2, level −20 dB. B envelope D 60 ms so the FM is only on the attack.
  2. Amp A 2 ms, D 180 ms, S 0, R 50 ms. Note length 1/16.
Send this to Return A at −15 dB. A faint echo of the bass pulse at 3/16 under the chord echoes is one of those things nobody identifies but everyone misses when it’s gone.

The hiss bed — Vinyl Distortion, Operator noise, Erosion, running from bar 0 to the end

Device: Vinyl Distortion, Operator, Erosion · Level: beginner · Genres: dub techno, lofi

A constant −30 dBFS bed of pink-ish noise, crackle and faint tape hum. This is the surface the whole track is drawn on. It never stops, never changes level, and is sidechained to nothing.

  1. Operator Osc A Noise (noise waveform), Filter LP 12 dB at 6 kHz. One long note for the whole arrangement.
  2. Vinyl Distortion: Crackle density 40%, Crackle volume −20 dB, Tracing model soft, drive 10%, Pinch off.
  3. Erosion Noise mode, 3 kHz, Width 1, Amount 25% for a slight modulated graininess.
  4. EQ Eight HP 80 Hz, high shelf −6 dB at 8 kHz. Utility −30 dB, Width 150%. Check it: solo the master, mute the hiss — the track should feel suddenly naked.
Continuous low-level noise raises the perceptual floor so quiet delay tails never "fall out" into silence. It also masks the start of fades, which is why dub techno transitions sound seamless even when elements are simply faded in.

Shaker and rimshot — Impulse, swung 1/16, lots of room

Instrument: Impulse · Level: beginner · Genres: dub techno

A soft shaker on every 1/16 with 56% swing and a dry rimshot on the and-of-2 and the and-of-4. Both go to a short plate (Hybrid Reverb) at 40%.

  1. Clip groove: Swing 16 at 56% (Groove Pool), velocity amount 30%.
  2. Impulse shaker slot: Filter LP 7 kHz, Decay 30%, velocity to volume 60%. Rim slot: Pitch −2 st, Decay 20%, Pan slightly right.
  3. Rim velocity 85, never accented. Its job is time-keeping, not punctuation.

Closed hat and ride — Drum Sampler, offbeat hat, 1/8 ride with slow Auto Filter

Instrument: Drum Sampler · Level: beginner · Genres: dub techno, deep techno

Closed hat on the offbeat 1/8 (bars 72–160), ride on straight 1/8 from 96, both dark. The ride is filtered to 2.5 kHz at entry and opens to 9 kHz across the swell.

Pad drone — Meld Swarm Sine on A1+A2, filtered, 60% reverb

Instrument: Meld · Level: intermediate · Genres: dub techno, ambient, drones

A low, slow drone that doubles the root. Meld’s Swarm Sine engine gives a cluster of detuned sines that sounds like a distant organ. It enters low in the intro, disappears, and returns at bar 128 for the rest of the track.

  1. Meld: Osc A engine Swarm Sine, Spread 30%, Osc B engine Dual Saw at −12 dB mixed low for grain. Filter A LP 400 Hz. LFO 1 sine 0.03 Hz → Filter A cutoff ±20%.
  2. Amp envelope A 6 s, S 100%, R 8 s. Voices: hold A1 and A2 together.
  3. If the 12.2 Scrambler is available, set it at 5% for occasional grain jitter — keep it near-inaudible.

Reverb swell — chord into a 12 s Hybrid Reverb, dry muted, 2 bars

Device: Hybrid Reverb · Level: beginner · Genres: dub techno

The transition device. For bars 94–96 (and 158–160, 206–208), the chord is sent 100% to Return C (a 12 s Dark Hall) and the dry chord and Return A are faded out. The reverb blooms, then on the downbeat the Return C send snaps to −inf and the dry chord returns. The reverb tail decays naturally under the new section.

Mix decisions

Gain staging. This mix is quieter and more compressed-feeling than deep techno, but by density not by compressor. Kick peaks −10 dBFS, sub RMS −16, chord dry peaks −18, Return A sits at −14 to −10 dBFS at peak feedback (it is the loudest element at the swell’s crest), hiss −30 RMS, percussion −22 to −26, pad −22 RMS. Master pre-limiter around −7 dBFS peak. Target −9 to −10 LUFS integrated — dub techno masters are famously not loud.

Sidechain sourceTargetAmount / shape
KickSub6 dB GR, attack 0.3 ms, release 110 ms, 5:1
KickReturn A (chord Echo)3–4 dB GR, attack 1 ms, release 150 ms — the groove of the echoes
KickBass pulse3 dB GR, release 80 ms
KickPad drone2 dB GR, release 200 ms
KickChord dry (Glue, ext. SC)1.5 dB GR, release 100 ms — barely audible, keeps the 110–160 Hz overlap clean
KickReturn C (swell)0 dB — the swell happens where the kick is quiet anyway, and pumping on a 12 s tail sounds cheap
— (none)Hiss bedNever sidechained. It is the floor.

EQ carving.

Bus structure.

There is no "tonal" bus here on purpose: the chord dry, Return A and Return C need to stay at independent levels because their balance is the arrangement. A Utility on the master in Mono mode is used for checking; the hiss bed’s 150% width and the Echo’s L/R time offset are the only intentional stereo content below 1 kHz, and both are HP’d above 180 Hz.

Width per element. Kick, sub, bass pulse: mono. Chord dry: 70% (Chorus-Ensemble vibrato adds no width; set Utility to 70%). Return A: 120%, with EQ Eight in M/S mode cutting the Side below 300 Hz. Return C: 140%. Hiss: 150%. Shaker/rim: 80%, rim slightly right. Hat and ride: 70% with Drum Rack pan ±40%. Pad: 110%.

Build it yourself in 10 steps

  1. New set, 122 BPM, scale A minor. Three returns: A = Echo system (3/16 L, 1/4 R, filter in loop, Roar after, kick-sidechained Compressor), B = Quartz plate 0.8 s for percussion, C = 12 s Dark Hall swell with a closing Auto Filter.
  2. Hiss bed first: Operator noise → Vinyl Distortion → Erosion → EQ → Utility −30 dB, one 240-bar note. Leave it on from now on; mix everything else on top of it.
  3. Kick: Operator sine A0, pitch env +14 st / 45 ms, amp D 550 ms, Drum Buss Boom 30% at 55 Hz, Transients −20%. Four-on-the-floor. Peak −10 dBFS.
  4. Sub (Drift half-notes, sidechained 6 dB) and bass pulse (Operator FM blip on the and-of-1/and-of-3). Both mono.
  5. Build the Dub Chord rack in Analog (pulse waves, slow PWM, LP 700 Hz). Program the 2-bar stab pattern with the and-of-2 hits. Set sends pre-fader: A at 0 dB, B off, C off. Map Cutoff, Decay, Dub send, Dry level to macros.
  6. Percussion in order of arrival: Impulse shaker + rim with 56% swing, Drum Sampler closed hat offbeat, Drum Sampler ride 1/8 with the 64-bar Auto Filter automation. All to Return B at 40%.
  7. Meld Swarm Sine pad drone on A1+A2, 6 s attack, kick-sidechained.
  8. Arrange 240 bars. Record the Echo feedback and LP cutoff as live automation on Push during the swell section (four 16-bar waves to 70/80/85/90%). Draw the three 2-bar swell sends to Return C at 94, 158, 206 with the dry chord and Return A muted for those 2 bars.
  9. Mix with the sidechain table and the four EQ curves. Mono-check below 180 Hz. Make sure the hiss is audible in the quietest moment of the outro and inaudible as a separate thing at the swell’s peak.
  10. Master: HP 25 Hz, high shelf −2.5 dB at 9 kHz, Glue 1 dB, Limiter −0.5 dB, −9 to −10 LUFS. Bounce in place; A/B compare at matched loudness against a classic in the style — if yours sounds brighter, it is too bright.

Variations

Deep techno. 128–130 BPM, the kick gets a +30 st pitch env and a 400 ms decay, a Roar-driven rumble return replaces the hiss bed as the glue, the chord becomes a minor 7 with saw waves, and the delay feedback never goes above 60%. See the deep techno deconstruction.

Dub house / deep house with dub FX. 120 BPM, swing to 58%, add a clap on 2 and 4 with a short plate, replace the Am9 stab with a Rhodes-style Electric chord (tine, soft mallet) through the same Echo system, and give the bass pulse a full 1/8 walking line (A1 G1 A1 C2). Shorten to 160 bars with a proper 16-bar breakdown at 96.

Ambient dub / beatless. Remove the kick, sub and all percussion. Keep the hiss, chord, Echo system and pad. Slow the chord pattern to one hit per 4 bars and push the Echo feedback to a resting 85% with the LP at 1.2 kHz. Add a second Meld voice (Rain engine, very low) and run the whole thing through Spectral Time in Freeze mode for 8 bars at a time as the transition device. 20 minutes long.
