TB-3 · MX-1 · TR-8S
Acid line, mixer hub, rhythm brain. This stop is not three separate manuals taped together — it is the live-rig lesson: one clock master, channel levels that leave headroom, and bus FX as arrangement.
Study recipes below are ready now; interactive AIRA labs are still in production. The module tour maps TB-3 accent/slide, MX-1 scenes and TR-8S TR-REC to Manual chapters and the Step Groove Machine so you can practise the ideas before every box is on the desk.

A.1
Module tour · three boxes, one rig
Read TB-3 for articulation, MX-1 for routing, TR-8S for grids — then the clock section so they start on the same downbeat. Each block cites Roland’s publicly linked manuals without rehosting PDFs.
TB-3 · fold-out · FILTER / TOUCH
TB-3 · touch pad as filter performance
The TB-3 is Roland’s AIRA take on the TB-303 bass line: a mono acid voice with cutoff, resonance, envelope modulation and decay, plus a touch pad that turns filter moves into choreography. Accent and slide still live in the sequencer — they are not optional garnish; they are the instrument.
Start with a short pattern (8–16 steps), leave the filter half-open, and practise one continuous pad gesture per bar rather than stabbing random XY spots. The ear learns the envelope of the filter before the fingers invent a dance.
- CUTOFF / FILTER
- Brightness of the voice — the main performance control.
- RESO
- Emphasis at the cutoff; high values whistle like classic acid.
- ENV MOD / DECAY
- How hard and how long the filter envelope bites each note.
- ACCENT / SLIDE
- Step flags: louder/brighter hits, and pitch glides between notes.
- TOUCH PAD
- XY performance surface mapped to filter (and related) parameters.
Practice · Write a 16-step pattern with three accents and two slides, then perform cutoff only on the pad for one chorus.
TB-3 · fold-out · PATTERN WRITE
TB-3 · pitch-then-time writing
Classic 303 workflow is pitch first, then time: enter the note numbers for the phrase, then decide which steps are rests, ties, accents and slides. The TB-3 keeps that mental model even when the UI is a touch pad and step keys.
A good teaching pattern uses a narrow pitch range (a fifth or less), sparse accents, and one slide into the downbeat. Complexity is for later — the filter needs room to speak.
- STEP KEYS
- Select which sixteenth (or subdivision) you are editing.
- NOTE / PITCH
- Scale degrees for the bass line.
- REST / TIE
- Silence or sustain across steps — the ●○– language from the 303 manual.
- CLEAR / COPY
- Safe ways to iterate without rewriting the whole phrase.
Practice · Program eight notes, then convert every other note to a rest and add one slide — hear the phrase breathe.
MX-1 · fold-out · CHANNEL / USB
MX-1 · channels as a live patchbay
The MX-1 is the hub of an AIRA live rig: analog and USB returns, per-channel tone and FX sends, and a master bus with scene recall. Treat each channel as a labelled cable into the mix — TB-3 on one, TR-8S on another, laptop stems on USB — then mix with your ears, not with solo buttons forever.
The supplementary signal-flow diagram from Roland is worth printing once: it shows how USB audio, external inputs and the mix bus nest. Knowing that diagram prevents ‘why is my kick in the reverb twice?’ nights.
- CHANNEL FADERS
- Relative level of each source in the live mix.
- TONE / FILTER
- Per-channel high/low tilt so boxes sit together.
- SEND / FX
- How much of a channel hits the shared effects.
- USB AUDIO
- Bidirectional audio with a DAW — stems in, mix out, or both.
- SCENES
- Snapshot mixes for verse / drop / breakdown.
Practice · Park TB-3 and TR-8S on two channels, duck the bass slightly under the kick with tone, then save a ‘drop’ scene.
MX-1 · fold-out · MFX / BFX
MX-1 · bus FX as arrangement
On a mixer, effects are arrangement tools: a short delay on hats, a filter sweep on the master, a temporary kill-EQ. The MX-1’s bus and master FX let you perform transitions without rewriting patterns on every box.
Rule of thumb: dry vocals/leads stay dry; rhythm and acid can share one tempo-synced delay. Automate FX amount more than FX type mid-song.
- MFX / BFX
- Master and bus effect slots — choose type, then amount.
- TEMPO SYNC
- Lock delay / rate parameters to MIDI clock.
- CUE / MONITOR
- Preview a channel before it hits the house mix.
Practice · On a four-bar loop, open a master filter for bars 3–4 only — feel the drop without changing the TB-3 pattern.
TR-8S · Owner’s p. 4–10 · INST
TR-8S · instruments as small synth voices
Each TR-8S track is a tiny synthesizer or sample player with its own tune, decay, and effects. The Manual chapters on envelopes and noise map directly onto kick, snare and hat parameters — you already know the jobs (source, shaper, mover).
AIRA’s strength is mixing classic TR modelling, FM, and user samples in one kit. Keep kits purposeful: one boom-heavy kit for house, one clicky kit for techno, rather than one kitchen-sink bank.
- INST SELECT
- Which voice you are editing (BD, SD, HH…).
- TUNE / DECAY
- Pitch and length — the two knobs that define most drum characters.
- CTRL / LAST STEP
- Performance and pattern length (odd lengths = tension).
- EFFECTS
- Per-instrument and master colour (drive, reverb, delay).
Practice · Mute everything but BD + CH, set last step to 15, and write a broken house groove before adding snare.
TR-8S · Owner’s · TR-REC · Reference · MOTION
TR-8S · TR-REC and motion
TR-REC is step programming with the classic 16 illuminated pads. Motion recording lets knob moves become part of the pattern — the same idea as filter automation on the TB-3, but per drum voice.
Accent and flam (where available) are performance flags, not ‘more velocity forever’. Use them sparingly so the ear still hears the grid.
- TR-REC
- Enter/exit step write for the selected instrument.
- CLEAR / COPY
- Iterate patterns without blank-canvas fear.
- MOTION
- Record parameter moves into the pattern.
- FILL / VARIATION
- A/B pattern flips and fills for live arrangement.
Practice · Record a filter motion on the hats for one bar only, then mute motion to A/B the difference.

Clock · who is the boss?
Pick one clock master. Common live choice: TR-8S as master → MX-1 passes or slaves → TB-3 follows MIDI clock. DAW sessions often flip that: laptop is master, everything else slaves.
When patterns drift, check cable type (DIN vs TRS MIDI), clock in/out settings, and whether USB is also sending clock (double clock = chaos).
- MIDI CLOCK IN/OUT
- Receive or transmit 24 PPQN tempo.
- START / STOP
- Transport that resets sequencers together.
- USB MIDI
- Same messages over USB — disable duplicates if DIN is already live.
Practice · Slave the TB-3 to the TR-8S, hit Start once, and confirm both loop points land on the same bar.
Study recipes
Live-rig drills you can run on paper, Boutique cousins, or the Step Groove Machine until dedicated AIRA labs ship.
TB-3 · study
Accent + slide skeleton
Eight notes, three accents, two slides — the minimum acid phrase that still grooves.
- Write pitches first in a narrow range (a fifth or less).
- Flag accents on steps that should spit; leave most steps dry.
- Add one slide into the downbeat and one mid-bar slide.
- Hand-ride cutoff; do not automate everything yet.
Hear · Accents jump; slides glue; filter performance is the third instrument.
SH-01A · Acid lineTB-3 · study
One-bar touch-pad chorus
One continuous pad gesture per bar instead of random XY stabs.
- Loop a 16-step pattern with moderate resonance.
- On bar 1: open cutoff slowly left→right on the pad.
- On bar 2: reverse the gesture.
- Record yourself — choppy pads mean practise smoother arcs.
Hear · A filter ‘chorus’ that breathes with the bar, not a glitch contest.
Signal Path · cutoff rideMX-1 · study
Drop scene with bus filter
Verse and drop as mixer scenes — arrangement without rewriting patterns.
- Park drums and acid on two channels at balanced levels.
- Save Scene A: dry, filter closed on master/bus.
- Save Scene B: open bus filter, slight delay send on hats.
- Flip A→B on the downbeat; leave the sequencers alone.
Hear · The drop arrives from the mix, not from new notes.
Manual · MIDI / clockTR-8S · study
Last-step 15 house skeleton
Odd length = tension. Mute everything but BD + CH first.
- Set last step to 15 on a BD + closed-hat pattern.
- Four-on-the-floor kick; hats on 8ths.
- Add snare/clap only after the loop feels hypnotic.
- Flip back to 16 and hear the ‘resolution’.
Hear · 15-step loop leans forward; 16 feels like home.
Step Groove MachineTR-8S · study
Hat decay motion write
One bar of hat-decay motion, then mute motion to A/B.
- Write a steady 16th closed-hat lane.
- Record decay opening across bars 3–4 only.
- Disable motion playback and compare.
- Keep motion sparse — if every bar moves, nothing surprises.
Hear · Hats bloom into the fill, then return to ticks.

Three-box clock lock checklist
One master, no double clock, shared start — the live-rig exam.
- Pick one clock boss (often TR-8S or laptop).
- Disable USB clock if DIN clock is already active (or vice versa).
- Slave TB-3 / Boutique / MX-1 as needed; verify MIDI thru paths.
- Hit Start once; confirm all loops land on the same bar-1.
Hear · Silence then a locked downbeat — no creeping drift after eight bars.

TB-3 ↔ TB-03 dialect drill
Same accent/slide phrase on AIRA pad grammar and Boutique knobs.
- Program the accent+slide skeleton on paper in ●○– notation.
- Enter it on TB-03 (or SH-01A seq) with knobs.
- Re-enter the same pitches/flags on TB-3 with the touch pad for filter only.
- Note which UI made accents clearer vs which made filter dances easier.
Hear · Identical phrase, two performance dialects — pick tools by song, not brand loyalty.

FAQ
- Why are TB-3, MX-1 and TR-8S one gear-route stop?
- They are the modern AIRA live cluster: acid line, mixer/hub, and rhythm. Learning them together teaches clock, levels and FX bus — skills that do not appear when you study one box alone.
- Is the TB-3 the same as a TB-303?
- Same cultural job (accent, slide, resonant filter bass), different circuit and UI. The canon stop covers the original 303; use TB-3 for touch-pad performance and AIRA integration.
- Do I need all three boxes?
- No. Practise patterns in the Step Groove Machine and acid moves on SH-01A or Hydrasynth first. When you own one AIRA unit, map that device’s module tour section and ignore the rest until the hardware arrives.
- Where are the official manuals?
- Roland’s support pages for TB-3, MX-1 and TR-8S host the Owner’s Manuals, MX-1 supplementary/signal-flow sheets, and the TR-8S Reference Manual. We cite pages; we do not rehost PDFs.
- Is there a browser playground for this stop yet?
- Not yet. Study recipes below use the Step Groove Machine, Signal Path / SH-01A / TB-03 Boutique cousins, and paper checklists until dedicated AIRA labs ship.
- What should I read before wiring a live AIRA rig?
- Manual chapters on filters, envelopes and MIDI, plus the MX-1 signal-flow diagram from Roland. Then decide a single clock master before connecting anything else.
- TB-3 vs TB-03 Boutique?
- TB-03 is the Boutique ACB panel recreation of the 303. TB-3 is the AIRA touch-pad instrument. Both teach accent/slide; pick based on whether you want pad performance (TB-3) or classic knobs (TB-03).
- Why is the MX-1 in a ‘synth’ curriculum?
- Live synthesis fails when levels, FX buses and clock disagree. The MX-1 is where arrangement happens without rewriting every box’s pattern.
- TR-8S vs TR-08 / TR-09?
- Boutiques are focused 808/909 recreations. TR-8S is the expandable AIRA rhythm workstation (samples, FM, motion). Learn kits on Boutiques or the Step Groove Machine, then graduate to TR-8S depth.
