Alright, welcome in. This is an advanced Ableton Live 12 composition lesson, and we’re going straight into jungle and oldskool DnB territory: the Reese bass, but not as a static “here’s a patch” situation.

Today’s goal is a Reese that can switch-up, break down, and rebuild without losing weight. And we’re doing it with an automation-first workflow. That means you’re not writing the bass line first. You’re writing the movement first. The bass notes are almost the boring part. The story is filter, dirt, width, throws, and the moment where everything resets so the drop feels like it just got bigger.

By the end, you’ll have a two-layer Reese rack: a mono-safe sub that stays dependable, and a mid layer that does the talking. You’ll build an eight-macro control panel, then arrange a 16-bar phrase that clearly reads as main roll, switch-up, rebuild, and a confident reset back into the groove.

Settle in, open Live 12, and let’s build this like you’d build a record, not a loop.

First, session prep. Put the tempo at 166 BPM. That’s a classic sweet spot where breaks roll properly and the bass has time to breathe without feeling sluggish.

Now make three groups: DRUMS, BASS, and MUSIC or FX. Keep it clean. This matters because later you’ll automate like a conductor, and you don’t want chaos in the routing.

Create three return tracks.

Return A is ShortVerb. Use Ableton’s Reverb. Decay somewhere between point-six and one-point-two seconds. Low cut around 250 to 400, high cut around 6 to 9k. Dry wet around 10 to 18 percent. This is your glue space, the “room.”

Return B is ThrowVerb. Same Reverb, but now it’s dramatic. Decay 3 to 6 seconds, pre-delay 20 to 40 milliseconds, and dry wet at 100 percent because it’s a throw. This is for single hits, punctuation, those jungle “whoosh” moments where the tail keeps going but the source disappears.

Return C is DubDelay. Use Ableton Delay, keep ping pong off, set it to one-eighth or one-quarter, filter it dark, feedback 25 to 45 percent. This isn’t modern sparkle delay. This is the oldskool, dubby, tucked-in repeat.

Here’s the mindset check: if you only add these sends at the end, you’re decorating. If you automate them as part of the phrase, you’re composing. That’s the whole automation-first idea.

Now build the Reese core. Create a MIDI track and name it BASS – Reese Rack.

You’ve got two solid instrument choices. If you want fast and controllable, use Wavetable. If you want that older, solid, more direct tone, use Operator. I’ll describe the Wavetable route, but you can translate the same rack concept to Operator easily.

In Wavetable: Osc 1 is a Saw. Set unison to two to four voices. Detune around 10 to 20. Osc 2 can be a Square or another Saw, with either unison off or just a little bit, detuned differently so the beating feels alive. If you want extra character, add a tiny bit of warp, Classic or a light FM, but stay subtle. Jungle reeses aren’t supposed to sound like modern bass design flexing. They’re supposed to feel like pressure.

Set the synth filter to a low-pass 24. Add a bit of drive, two to six dB. Put the cutoff somewhere around 200 to 600 to start. Don’t worry about “perfect” yet.

Now the must-do for DnB: split into sub and mid. Drop an Audio Effect Rack right after your instrument. Create two chains. Name them SUB and MID.

On the SUB chain, add EQ Eight first. Low-pass it around 90 to 120 Hz. If it feels boxy, you can dip a bit around 200 to 300, but keep it gentle. Then add Saturator. Soft Clip on. Drive one to four dB. Then Utility. Set width to zero percent. Mono sub, no debate. Adjust gain so it’s strong but not clipping.

The sub should be boring on purpose. If your sub is doing tricks, your drop becomes inconsistent on different systems. We want the sub to behave like a foundation.

On the MID chain, start with EQ Eight and high-pass around 90 to 120 Hz. That keeps the low end clean and leaves room for the sub chain to own the weight.

Then add Chorus-Ensemble. Put it in Chorus mode. Rate around 0.2 to 0.6 Hz, amount 20 to 40 percent, width 80 to 120. This gives movement without turning it into a trance supersaw.

Then add Saturator. Drive four to ten dB depending on how rude you want it. Soft Clip on. After that, add Erosion for grit. Set it to Noise mode. Frequency 4 to 8k. Amount around 0.5 to 2.5. You’re not trying to hear “white noise.” You’re trying to feel that sandpaper on the edges, that early-techstep texture.

Then add Auto Filter. Type LP12 or band-pass if you want it more nasal. Resonance around 0.7 to 1.4. Keep envelope amount low or off because we’re going to automate manually. This filter is your main movement engine.

Quick checkpoint: play a note. If it sounds huge but messy, that’s normal. We haven’t organized the behavior yet. That’s what macros are for.

Now we build the automation-first performance panel. In your Audio Effect Rack, map eight macros. Name them clearly because you’re going to live in these lanes.

Macro 1: Reese Cutoff. Map it to the Auto Filter cutoff on the MID chain.
Macro 2: Reese Reso. Map it to Auto Filter resonance on the MID chain.
Macro 3: Dirt. Map it to the MID Saturator drive.
Macro 4: Width. Map it to Utility width on the MID chain only. Leave the sub mono.
Macro 5: Chorus Amt. Map it to the Chorus-Ensemble amount.
Macro 6: Bite. Map it to Erosion amount.
Macro 7: Sub Push. Map it to the SUB Saturator drive, but keep the range small.
Macro 8: Air or LP. Optional. You can map a high shelf on an EQ after distortion, or a gentle low-pass tone control for the mid.

Now, the pro move: set safe mapping ranges so you can automate aggressively without accidentally destroying the mix.

For Cutoff, set a range like 120 Hz up to 4.5 kHz. That gives you “under the floor” all the way to “tearing brightness” without going ultrasonic.
For Width, set 40 percent to 140 percent. That prevents the mid from living at ridiculous width all the time.
For Dirt, maybe 3 dB to 12 dB.
For Bite, 0 up to 3.

This matters because when you’re composing automation, you want to be thinking musically, not thinking, “please don’t blow up my ears.”

Here’s the workflow rule for the whole lesson: you are going to write your arrangement by automating these macros before you obsess over MIDI notes.

So let’s write the MIDI in the most minimal, intentional way.

Create an eight-bar loop. Choose a key like F minor or G minor. Keep it simple. Jungle reeses often sit on one note and let the movement make it feel like it’s talking.

Bar one to two: one sustained note. Let’s say F1.
Bar three to four: same note, but add a short pickup, a sixteenth or an eighth, so it has a little phrase.
Bar five to six: step to Eb1, or use a fifth or seventh depending on your vibe. That step creates tension without needing a busy pattern.
Bar seven to eight: back to F1, but create one syncopated gap. Literally let it go silent for a moment. Silence is groove. Silence is also the best “automation reveal” because you feel the return.

Timing tip: if your drums are aggressive, nudge the MIDI a couple milliseconds late, like two to ten milliseconds. It can make the bass sit behind the break instead of fighting it. If you want an even more advanced feel later, you can delay only the mid layer so the sub hits first and the growl blooms after.

Now we build the switch-up section. Think 16 bars. Bars one to eight is your main roll. Bars nine to twelve is switch-up, controlled chaos. Bars thirteen to sixteen is rebuild and drop confirmation.

Before we get fancy, do automation in passes. This is a huge coaching point.

Pass one is the big silhouette. Only cutoff and width. That’s it. You’re drawing the energy curve like a DJ would feel it: open, close, squeeze, release.

So for bars one to eight, keep cutoff medium, around 600 to 1.2k, and width moderate, around 80 to 110 percent. Just rolling, stable. This is where the listener learns what “normal” is.

Bars nine to ten, switch-up entry: dip the cutoff down to around 300 to 500. Narrow the width towards 50 to 70 percent. Notice what that does: it makes the bass feel like it steps back, like the room tightens. That creates space for break manipulation and FX, and it tells the dancefloor, something’s changing.

Bars eleven to twelve, switch-up peak: sweep the cutoff up fast to around 2 to 4k. Bring resonance up slightly, but don’t let it whistle. We want bite, not a synth demo. Width can widen briefly here, but we’re going to pull it back before the drop.

Bars thirteen to sixteen, rebuild: bar thirteen, pull cutoff down again and narrow width. Focus. Bar fourteen to fifteen, gradually rise cutoff again. Then in the last bar, do a hard reset back to your “main” values. Cutoff back to the main roll. Width back to main roll. That reset is everything, because the drop feels bigger when you return to something stable and centered.

Okay. Pass two is attitude. Now you add Dirt, Bite, and maybe Chorus Amount, but only where needed. Not everywhere.

In bars one to eight, keep Dirt steady, like six to eight dB. Bite low, like 0.5 to 1.2. Chorus amount moderate.

Bars nine to ten, reduce Dirt slightly. This is counterintuitive for people: you think switch-up means “more distortion,” but often the entry needs less. Pulling back makes room. It also sets up the peak so the peak actually means something.

Bars eleven to twelve, push Dirt and Bite up. This is where the Reese tears for a moment. You can also automate a tiny bit of comb-like movement here by adding Phaser-Flanger in flanger mode with low feedback and mapping its amount to a macro range that’s safe. Only for the peak, then back to near zero before the drop.

Pass three is punctuation. This is where you automate send throws and tiny dips right before hits.

Here’s a classic move: in bars nine to ten, pick one or two bass hits and automate a quick send to ThrowVerb. Don’t bathe the bass in it. Just a stab that disappears into a long tail. That’s the “question mark.”

Another punctuation move: right at the end of bar twelve, do a quick stop. Mute the mid for an eighth note, or even a quarter, but keep the sub going. Then throw one hit into ThrowVerb and cut it. That negative space feels loud because the tail plus sub continuity tricks the ear into hearing size.

Now, make it jungle with the break. Put a break in your DRUMS group, Amen, Think, whatever fits your vibe.

Add Beat Repeat on the DRUMS bus. Set interval to one bar, grid to one-sixteenth, chance at zero, variation around five to fifteen, filter on to taste.

Then automate Chance so it only comes alive during bars eleven to twelve. Somewhere between 20 and 60 percent is usually enough. This is important: Beat Repeat should feel like a deliberate moment, not like your drums are permanently glitching.

Add Auto Filter on the break too. As you enter the switch-up, sweep a high-pass up. Thin it out. Then snap it back before the drop. That snap is like a breath being released.

Now glue the bass and drums with sidechain, but keep it tight, not EDM pumping.

On the BASS group, put a Compressor. Sidechain it from the kick, or a kick-plus-snare ghost channel if you’re fancy. Ratio two-to-one up to four-to-one. Attack 10 to 30 milliseconds so the transient gets through. Release 60 to 120 milliseconds. Aim for one to three dB of gain reduction in the main section, and maybe a bit more in the switch-up if the break is going wild.

Now for the advanced part that makes it feel like a record: resampling for rebuild impact.

Create a new audio track called BASS – Reese Resample. Set its input to Resampling, or take the output from the Reese track directly. Record eight to sixteen bars that include your switch-up automation.

Now go hunting. Find a one-bar moment in bars eleven to twelve where the Reese feels especially nasty, like the beating locks in, the distortion is perfect, the filter is in the sweet spot. Grab it.

Take that one bar and reverse it, or fade it in, and use it as a riser into bar sixteen. Add 100 percent wet reverb, then an Auto Filter sweep so the tail stays dark and not splashy. The jungle vibe is dark space, not shiny space.

And here’s the key discipline: for the actual drop, return to the original MIDI Reese rack. That’s your stable, mix-consistent bass. Sprinkle the resample as ear candy and tension, but don’t let the resample replace your foundation unless you really know it translates.

If you want to push it even further, you can load that resampled half-bar into Simpler in Classic mode and play it like a stable hit. That’s a sampled-era trick: you freeze the best wobble into something repeatable.

Let’s outline a practical 16-bar layout you can literally copy.

Bars one to eight: full drums, main Reese with mild automation. Occasional dub delay throw on the snare at bar ends, every two or four bars. Keep it restrained.

Bar nine: remove some hats, narrow the bass, high-pass the break a bit. The floor should feel like it’s leaning forward.

Bar ten: add a one-shot stab or a vocal chop. That classic rave flavor. Even quiet, it tells the listener: we’re in jungle land.

Bar eleven: Beat Repeat chance up. Reese cutoff up, Bite up. This is the peak question.

Bar twelve: quick stop-start. Mute the mid for the last eighth. Big reverb throw tail.

Bar thirteen: bring back sub with minimal mid. Simplify drums. Let people reorient.

Bars fourteen to fifteen: snare build, rising noise if you want, bass cutoff rises steadily, Dirt rises slightly. You’re building inevitability.

Bar sixteen: full drop reset. Everything tight, centered, confident. No weirdness right on the impact. This is where you win.

Now, common mistakes to avoid, because these are the exact reasons people’s switch-ups sound cool solo but fall apart in a track.

Mistake one: stereo sub. If your sub isn’t mono, your drop will feel weak in clubs and weird in mono playback. Utility width zero on the sub chain.

Mistake two: over-automating too early. If you draw a hundred tiny moves, you lose the storyline. Start with two or three headline macros: cutoff, width, dirt. Then add details.

Mistake three: resonance whistling. If your Auto Filter resonance gets too proud, it screams “preset.” Keep it controlled.

Mistake four: no reset before impact. If you’re max-wide and max-distorted on the downbeat, there’s nowhere bigger to go. The reset is what makes the drop feel like a drop.

Mistake five: switch-up equals random. Chaos needs structure. Work in two-bar ideas. Repeat them with variation. Jungle is DJ-functional: recognizable patterns that evolve.

Two more advanced upgrades if you want extra flavor without adding new notes.

One, two personalities inside one rack. Duplicate the MID chain into MID A and MID B. MID A is your smooth main, chorus, moderate drive. MID B is harsher: heavier distortion, maybe band-pass filtering, maybe a tremolo effect. Then map a macro to chain selector or chain volumes so you morph between A and B during bars nine to twelve. This gives “new record” energy without changing the bass line.

Two, rhythmic gating without sidechain pumping. Put Auto Pan after the MID chain, set phase to zero degrees so it becomes tremolo. Rate one-eighth or one-sixteenth, amount 10 to 35 percent. Automate the amount up only in the switch-up. Sub stays steady, mid starts chopping, instant oldskool electricity.

Before you export anything, do a translation check during the rebuild. Put a Utility at the end of the BASS group, temporarily. Toggle width to zero for a mono check. Then pull gain down six dB for a headroom check. If your rebuild loses the pull in mono, you’re relying too much on width. If it collapses when you lower level, you’re relying on distortion “loudness” rather than solid mid fundamentals.

Now your mini practice exercise, the fast version.

Build the Reese rack with the sub and mid split and eight macros.
Write one-note MIDI on F1 for eight bars.
Create a 16-bar automation story using only cutoff, dirt, and width. Only those three.
Add one break. Automate the break’s high-pass entering bars nine to twelve. Automate Beat Repeat chance only in bars eleven to twelve.
Resample eight bars and use a reversed one-bar snippet as a pre-drop riser.
Export a 16-bar loop that clearly reads: main, switch-up, rebuild, drop reset.

And here’s your deeper homework challenge if you want to level up for real: make three switch-ups from the same bass notes. No changing the MIDI. Only automation, rack routing, and resampling.

Version A is classic: narrow, bright peak, hard reset. Only cutoff, width, dirt.
Version B is dubby: minimal distortion, heavy punctuation with ThrowVerb and DubDelay.
Version C is techstep edge: morph to the harsher MID B and add tremolo gating.

If you do that, you’ll have something most producers don’t have: one bass line that can tell multiple stories, which is basically the secret of making DnB arrangements that don’t get boring.

Final recap to lock it in. A jungle Reese isn’t just a sound. It’s an arrangement engine. Keep the sub mono and stable. Give the mid movement and controlled nastiness. Build macros like scene faders, not random knob-wiggling. Automate in three passes: silhouette, attitude, punctuation. Use the break to drive the switch-up, not just the bass. Resample the best moments for tension, but come back to the stable MIDI rack for the drop.

If you tell me your exact reference, like early Ed Rush and Optical techstep versus ragga-jungle versus more modern roller, I can suggest specific macro ranges and an exact automation curve shape for bars nine through sixteen that matches that sound.
