Welcome back. This is an advanced sound design session for drum and bass, and we’re going to build something very specific: a neurofunk bass processing rack that turns a raw bass source into a controllable, mix-ready system.

Because in neuro, the bass isn’t one sound. It’s a machine made of separate jobs: sub stability, low-mid weight, midrange attitude, top texture, and then a final polish stage so it behaves in the mix and resamples well.

By the end, you’ll have one Ableton Audio Effect Rack with four parallel chains: Sub, Lowmid, Mid, and Air. And we’ll map eight macros so you can perform the bass like an instrument and automate it quickly in a rolling 174 style.

Before we touch the rack, prep your source. This matters more than people want to admit. Neuro processing rewards consistency. If you’re working from a synth, freeze and flatten a few bars of your riff, or record it to audio. Then consolidate a clean loop so you’re not dealing with random level jumps or weird tails.

If you’re starting from audio, set a warp mode that doesn’t destroy the character. Complex Pro is often a great starting point for resampled neuro movement. If it’s super transient-heavy, Beats might behave better. And level-wise, aim so your bass is not slamming the track before the rack. Roughly minus twelve to minus six dB peak going in is a solid target. Give the rack room to work.

Now build the rack. Drop an Audio Effect Rack onto the bass track or your bass group. Open the Chain List and create four chains named SUB, LOWMID, MID, and AIR.

Think of these chain EQs as crossovers. Not just tone. Crossovers. That means phase and overlap matter. A huge part of “why does my bass sound hollow or woofy” is two chains fighting over the same band. A practical rule: let one chain own the 120 to 220 zone, usually LOWMID, and keep MID high-passed higher than you think. You can add body back through harmonics later.

Let’s start with the SUB chain: mono, stable, ruthless control. The job is simple. It has to hit hard, translate in clubs, and not wobble around like jelly.

First device: EQ Eight. Put a lowpass around 80 to 110 Hz. Go steeper if you need, 24 or 48 dB per octave. Optional move: if your kick fundamental lives around 50 or 60 Hz and the bass is stepping on it, do a small dip around 40 to 60. Small. We’re carving a pocket, not deleting the sub.

Next device: Utility. Turn Bass Mono on, set it around 120 Hz, then set Width to zero percent. This is not negotiable if you want solid mono translation. Adjust gain so the sub feels present but not like it’s taking over the room.

Then add compression. You can use Compressor or Glue. Try a 4 to 1 ratio, attack around 10 to 30 milliseconds, and release either Auto or around 80 to 150 milliseconds. You’re aiming for maybe 2 to 4 dB of gain reduction on peaks. The feeling you want is “pinned,” not “pumping.”

Optional, but often helpful: Saturator with very subtle drive, like 1 to 3 dB, Soft Clip on. The goal is not distortion. The goal is a little harmonic content so the sub reads on smaller systems without getting louder.

Quick coaching note: keep movement above the sub region. Neuro is all about motion, but sub motion is where mixes fall apart. Let the mids do the talking.

Now the LOWMID chain: body and punch without mud. This is where you get that wooden, chesty weight that makes a rolling bass feel expensive.

Start with EQ Eight. Highpass around 70 to 100 Hz so you’re not overlapping too hard with the sub. Then lowpass around 300 to 500 Hz. You’re basically isolating the “push” region. If it starts clouding the snare body, check 180 to 250 and either cut a little or automate that cut during busy moments.

Add Drum Buss. This is a classic Ableton sleeper for neuro lowmids. Drive somewhere around 5 to 15 percent. Crunch low, like 0 to 10. Boom at zero unless you have a very specific reason, because Boom can mess with phase and low-end perception fast. Use Damp to keep it from turning into fizzy garbage.

Then Glue Compressor. Ratio 2 to 1. Attack 3 milliseconds for more clamp, or 10 milliseconds if you want the transient to breathe a bit. Release around 0.1 to 0.3 seconds. Soft Clip on. Aim for 1 to 3 dB of gain reduction just to keep the lowmid consistent.

Now the MID chain. This is the neuro engine. Controlled chaos. This is where the identity lives: growl, formant-ish speech, aggression, and movement.

Start with EQ Eight. Highpass around 150 to 250 Hz. And here’s the advanced mindset: you might be tempted to keep more lowmid in this chain because solo it sounds huge. Don’t. Let LOWMID own the weight. Let MID own the character. Lowpass somewhere between 3 and 8 kHz depending on how much top you want generated here.

Now put in Auto Filter. Choose band-pass or low-pass. Turn Drive up a bit, like 2 to 8, because the filter drive is part of the tone. Turn the envelope off for now and keep it simple. Map the filter frequency to a macro later, because this becomes your “talking” control. For rolling DnB, automate that filter frequency in 1/8 or 1/16 patterns so it locks to the grid and feels like it’s answering the drums.

Next: Saturator. This is your main grit stage. Analog Clip or Wave Shaper. Drive can be big here: 6 to 18 dB. Soft Clip on. But gain-stage it. Use output compensation so you’re not confusing louder with better.

After that: Amp. Ableton’s Amp is ridiculously useful for neuro mid contouring. Try Rock or Heavy. Gain around 3 to 8. Keep the midrange slightly boosted, use Presence to taste, and be careful with treble if it gets spitty.

Then Redux, but treat it like a spice, not the meal. Downsample maybe 1.5 to 6 kHz, bits around 8 to 12, and keep Dry/Wet low, like 5 to 25 percent. Map that Dry/Wet to a macro called Robot, because that’s exactly what it does: instant machine edge.

Advanced safety tip: Redux before filtering can generate brittle wideband trash. If your sound is getting too fizzy and uncontrollable, try moving Redux after a filter stage so the filter decides what Redux is allowed to destroy. It makes the bite more intentional.

Then finish the MID chain with another EQ Eight for cleanup. Find the scream zone, often 2.5 to 3.5 kHz, and notch it. If it needs more “speech,” try a small shelf or bell boost somewhere around 700 Hz to 1.2 kHz.

And here’s a powerful neuro trick you can add: pre-emphasis into distortion. Put an EQ before Saturator that boosts a narrow band, like 700 Hz or 1.2 kHz, distort, then cut that same band afterward. The distortion grabs the boosted area and creates character, but you don’t end up with a permanently nasal tone. If you want to get fancy, map that pre-boost to a macro called Bark.

Now the AIR chain: texture and width, safely. This is where you add fizz, bite, and stereo shimmer without compromising mono power.

Start with EQ Eight. Highpass at 2 to 4 kHz. Optional lowpass 12 to 16 kHz if it’s too bright.

Add Overdrive. Set the frequency around 2 to 6 kHz, drive maybe 10 to 40 percent, and keep Dry/Wet controlled, like 10 to 35. This is brightness seasoning.

Then add Chorus-Ensemble or Phaser-Flanger, very lightly. Slow rate, low depth. If you hear obvious “whoosh,” it’s probably too much. In neuro, modulation should feel like texture, not like an EDM lead.

Then Utility at the end of the AIR chain. Set width around 130 to 170 percent. And turn Bass Mono on, set around 200 to 300 Hz just to be extra safe. The rule is simple: stereo is for upper harmonics only.

Now we map macros. This is where the rack becomes playable.

Macro 1: Sub Level mapped to the SUB Utility gain.
Macro 2: Body Level mapped to the LOWMID chain gain. If you don’t have a Utility there yet, add one so you can control it cleanly.
Macro 3: Grit Level mapped to MID chain gain.
Macro 4: Air Level mapped to AIR chain gain.
Macro 5: Talk Filter mapped to the Auto Filter frequency in MID.
Macro 6: Dist Drive mapped to Saturator drive, and optionally Amp gain.

But do macro mapping hygiene here. If one macro drives multiple distortion stages, set smart ranges. Give Saturator a big range, like 0 to plus 18 dB, and give Amp a small range, like 0 to plus 5 gain. That way it feels musical instead of “nothing… nothing… chaos.”

Macro 7: Robot mapped to Redux Dry/Wet.
Macro 8: Width mapped to AIR Utility width.

Now, two workflow moves that will save you from wasting hours.

First: treat this rack like a parallel mastering chain. Don’t crank each chain until it sounds exciting solo. That’s how you get harsh mush. Instead, build it like a mix.
Dial the SUB first, quiet but solid.
Bring in LOWMID until you feel weight.
Add MID until you get identity and speech.
Sprinkle AIR last, just enough to feel finished.
And keep toggling the whole rack on and off while level-matching. If it only sounds “better” because it’s louder, you’re lying to yourself.

Second: do a mono check early. Put a Utility after the entire rack and set Width to 0% to check mono translation. If the groove collapses, your AIR is too loud or too wide, or your MID modulation is causing phasey cancellations. Fix it now, not after you build the whole drop.

Now add your post-rack mix-ready stage. After the rack, add EQ Eight and highpass at 20 to 30 Hz to remove rumble. If the bass feels boxy, a gentle dip at 250 to 400 can help, but don’t automatically scoop it; listen with drums.

Then Glue Compressor: ratio 2 to 1, attack 10 ms, release Auto, and keep it light, like 1 to 2 dB of gain reduction max. This is glue, not destruction.

Then a Limiter as safety. Ceiling minus 0.3 dB. It should only catch occasional peaks, maybe 1 to 2 dB.

At this point, you have a rack that’s designed for resampling. And that’s the real neuro workflow: you perform automation, record it, and then comp it.

Here’s a mini exercise to lock it in.

Make a 16-bar rolling drop bass with two phrases. Start with a simple bass pattern or a sustained note and resample it to audio if needed. Put the rack on it.

For bars 1 through 8, automate the Talk Filter in a steady 1/8 pattern. Keep Dist Drive moderate. You want it speaking, but not screaming.

For bars 9 through 16, increase Drive slightly. Add small Robot moments: bring Redux mix up just on the last two beats of every second bar, like little glitchy fills. Then on bar 16 only, bump Air Level as punctuation to set up the transition.

Resample the output to a new audio track. Then slice out the best four to eight hits and rearrange them into a new two-bar call and response. This is the cheat code: resample in passes and comp like a vocalist. Three to five takes with different macro performances, then build a “best of” bass line from the best moments.

If you want an even more advanced variation, duplicate the MID chain into MID A and MID B. Make MID A smoother, less Redux, less Amp. Make MID B nastier, more resonance, more robot edge. Then use Chain Selector mapped to a macro called Phrase Switch so you can flip between them every bar or even every beat for that conversational neuro phrasing, without duplicating tracks.

Final reminders before you go build:
Keep the sub mono. Always.
Choose who owns the lowmid band so chains don’t fight.
Level-match distortion stages as you go, not just the final output.
And automate with intention. Usually one main moving element, plus one supporting change. If everything moves, nothing speaks.

Now go build the rack, run the 16-bar exercise, and resample a few takes. If you tell me your root note and where your kick fundamental sits, around 50 or 60 Hz, I can suggest tighter crossover points and where to carve a clean kick pocket between SUB and LOWMID.
