Welcome. This is an advanced mastering workflow in Ableton Live 12: InsideInfo edit — rebuild a roller groove from scratch for timeless roller momentum. Over the next walk-through you’ll learn how to resample a near-final Drum & Bass mix, convert that resample into a playable roller instrument, and glue that roller into a mastering chain using only Live’s stock devices — preserving subs, controlling transients, and keeping perpetual forward motion.
What you’ll build: a master-channel-safe roller bus resampled from your mix that provides rhythmic movement via panning, delay and width modulation; a mastering chain made from Utility, EQ Eight, Multiband Dynamics, Glue Compressor, Saturator and Limiter tuned to keep the low end intact while opening mids and highs; and a mid/side and transient management approach so the groove translates across playback systems.
Before we start, work at your final project tempo — usually 170 to 174 BPM — and have either stems or a stereo mix loaded into Live.
Section A — Prep and listening:
Create a new Group track named MASTER_PRE and route all your mix output into it. Duplicate MASTER_PRE to MASTER_SAFE so you can experiment non-destructively. Do a critical listening pass with MASTER_PRE soloed. Note where the groove feels loose or lifeless — usually hats, percussion and mid-high arps — and where rhythmic energy is missing.
Section B — Create a Roller Bus by resampling:
Create a new audio track called ROLLER_RESAMPLE. Set its Audio From to Master or to MASTER_PRE if you want to avoid any final limiter artifacts. Arm the track and enable global record. Record a few bars — 8 to 16 bars is a good starting point — while the song plays. You’re capturing the elements that create groove: hats, rides, stabs and FX tails.
Drop the recorded clip into a new MIDI track using Simpler. In Simpler use Slice mode — Slice by Transient or set a fixed grid of 1/16 — so the clip becomes a playable instrument you can re-sequence into a roller.
Section C — Sculpting the roller pattern:
In Simpler, choose Slice by Transient or set slice spacing between 1/16 and 1/8 depending on resolution. Map slices across the keyboard and create a MIDI clip that re-triggers slices in a 16-step pattern that “rolls” — try 1/16th triplets or staggered 1/16 velocities to emulate an InsideInfo-style bounce.
Use velocity modulation to vary slice loudness and the filter cutoff per hit. Map Simpler’s filter envelope and a small velocity-to-filter amount so velocity influences both amplitude and brightness. Program accents on quarter-note positions and micro-variations between them. Humanize lightly with tiny timing offsets for a natural feel.
Add an FX chain on the ROLLER_RESAMPLE track:
- EQ Eight (Stereo): high-pass at roughly 100 Hz to protect sub, and a gentle boost around 2–5 kHz of about +1.5 to +2 dB for clarity.
- Utility: set Width to 120–140% for material above 250 Hz; below 120–140 Hz set Width to 0% — this will be automated or handled via low/high splits.
- Auto Pan: subtle LFO synced at 1/8 to 1/4, triangle or sine shape, amount around 30–40% to create stereo roll. Offset phase between channels when needed.
- Ping Pong Delay: time between 1/16 and 1/8 dotted, feedback 15–25%, Dry/Wet about 12–18%. Use the delay filter to roll off everything below about 800 Hz so repeats don’t eat the sub.
- Compressor or Glue Compressor for sidechain ducking if necessary: use sidechain from the kick with a ratio between 2:1 and 4:1, fast attack and tempo-synced release to maintain bounce.
Section D — Integration: mid/side and low management on the master bus:
Place EQ Eight first on MASTER_SAFE and switch to M/S mode for surgical moves. In the Mid channel, consider a slight 1–2 dB boost between 100–200 Hz to glue kick and bass if needed. In the Side channel, a small high-shelf above 6–8 kHz of around +1 dB opens the top without affecting mono lows. If the roller introduces muddiness, a narrow cut in the Side around 300–600 Hz can help.
Next, add Utility after EQ Eight. Keep overall width at 100% but automate or tighten width to 0% under 120–140 Hz. For stronger control, create a low-mono split: duplicate MASTER_SAFE into MASTER_LOW and MASTER_HI. On MASTER_LOW apply a low-pass at 120 Hz and Utility width 0% to force mono. On MASTER_HI high-pass at 120 Hz and process as the wider band. Blend the two groups to taste.
Section E — Multiband Dynamics to tighten and expand:
Add Multiband Dynamics on MASTER_SAFE or MASTER_HI after your split. Use three bands — Low under 120–150 Hz, Mid, and High. For the Low band use gentle compression, ratio around 1.5–2:1, catching 1–2 dB of GR with a fast release for tight DnB. On the Mid band, try slight upward expansion or gentle upward compression to accentuate roller shimmers — fast attack, medium release. High band compression should be very transparent to keep top-end consistent without letting delays poke out.
Section F — Glue and transient management:
Place Glue Compressor after Multiband Dynamics to bind the bus. Use a relatively slow attack (10–30 ms) so primary transients pass, release on Auto or tempo-ish values around 100–200 ms, ratio 1.5:1 to 2:1. Aim for 1–2 dB of gain reduction. If you want extra character, use Drum Buss on a parallel track or send with a low mix amount — 10 to 25 percent — to add saturation and transient shape without killing definition.
Section G — Final saturation and limiting:
Insert Saturator with Soft Clip before the Limiter. Use modest Drive, around 1–3 dB, mode set to Analog Clip or Soft Sine, and keep Dry/Wet low — 10–20% or use a parallel return. For the final limiter, set ceiling to -0.3 dB and drive gain to hit your target LUFS. For DnB aim around -9 to -7 LUFS integrated for club-ready masters, while watching peaks and preserving transient punch. If limiting destroys the roller rhythm, reduce upstream compression, drop limiter gain, or use parallel limiting.
Section H — Automation and groove lock:
Automate the roller bus send level across the arrangement: lift it in drops and breakdowns for more forward motion, pull it back in bass-heavy parts to avoid masking. Use the Groove Pool to extract timing from a reference roller if you need micro-timing lock, applying swing and small randomization. Don’t over-quantize; keep human jitter for life.
Common mistakes to avoid:
- Summing the roller full-range into the stereo master without a high-pass — causes sub cancellation and mud.
- Over-saturating or over-limiting the roller, which kills transient definition and the feeling of roll.
- Big mid/side boosts without mono checking — wide highs that collapse in mono will betray you.
- Excessive master compression that flattens rhythm; prefer parallel compression if the groove goes static.
- Not checking on multiple systems — what’s lush on monitors can be smeary on small speakers.
Pro tips and practical refinements:
Resample short sections at higher sample rates and work with 4–8 bar chunks for precision. Emphasize the first slice transient slightly — small transient boosts or Drum Buss transient knob helps it cut. Keep sub strictly mono and stereo movement above 120–150 Hz. Use tempo-synced subtle modulation like Auto Pan at 1/8 or 1/4 instead of extreme panning. When in doubt about loudness, reference to -9 LUFS and keep an unprocessed peak-safe stem.
Mini practice exercise:
Take a 16-bar loop at 174 BPM. Resample 8 bars, put the clip into Simpler with Slice by Transient. Program a 1-bar MIDI pattern at 1/16 steps with varying velocities, accenting every fourth 1/16. Add EQ Eight HP at 100 Hz, Auto Pan at 1/8, Ping Pong Delay at 1/16 dotted with 18% feedback and 15% wet, and Utility to widen above 250 Hz. Build a master chain with EQ Eight M/S corrective moves, Multiband Dynamics with gentle low compression, Glue Compressor for about 1.5 dB GR, Saturator soft clipping at low wet amount, and Limiter ceiling at -0.3 dB. Export two versions: with the roller and without. Compare energy and note gain staging.
Recap:
You’ve learned to resample and rebuild a roller groove with Simpler and Live’s stock FX, to craft motion with Auto Pan and Ping Pong Delay, and to integrate that roller into a mastering chain that protects sub weight and transient punch. Key mastering moves are mid/side EQ surgery, low-mono splitting, multiband dynamics, gentle glue compression, tasteful saturation, and limiter restraint. The goal is a timeless roller that sits on the master without sacrificing club-level low end or transient clarity.
Final note: think of the roller as a mastering-era “momentum insert” — work non-destructively, match loudness when A/B’ing, and save iterations. Timebox experiments and always check your results on multiple playback systems. Good luck — rebuild your roller, feel the forward motion, and keep the bass tight.
