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.

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.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. MX-1 · MIDI · TR-8S Reference · MX-1 MIDI

    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.

    Accent + slide skeleton

    Eight notes, three accents, two slides — the minimum acid phrase that still grooves.

    1. Write pitches first in a narrow range (a fifth or less).
    2. Flag accents on steps that should spit; leave most steps dry.
    3. Add one slide into the downbeat and one mid-bar slide.
    4. Hand-ride cutoff; do not automate everything yet.

    Hear · Accents jump; slides glue; filter performance is the third instrument.

    One-bar touch-pad chorus

    One continuous pad gesture per bar instead of random XY stabs.

    1. Loop a 16-step pattern with moderate resonance.
    2. On bar 1: open cutoff slowly left→right on the pad.
    3. On bar 2: reverse the gesture.
    4. Record yourself — choppy pads mean practise smoother arcs.

    Hear · A filter ‘chorus’ that breathes with the bar, not a glitch contest.

    Drop scene with bus filter

    Verse and drop as mixer scenes — arrangement without rewriting patterns.

    1. Park drums and acid on two channels at balanced levels.
    2. Save Scene A: dry, filter closed on master/bus.
    3. Save Scene B: open bus filter, slight delay send on hats.
    4. Flip A→B on the downbeat; leave the sequencers alone.

    Hear · The drop arrives from the mix, not from new notes.

    Last-step 15 house skeleton

    Odd length = tension. Mute everything but BD + CH first.

    1. Set last step to 15 on a BD + closed-hat pattern.
    2. Four-on-the-floor kick; hats on 8ths.
    3. Add snare/clap only after the loop feels hypnotic.
    4. Flip back to 16 and hear the ‘resolution’.

    Hear · 15-step loop leans forward; 16 feels like home.

    Hat decay motion write

    One bar of hat-decay motion, then mute motion to A/B.

    1. Write a steady 16th closed-hat lane.
    2. Record decay opening across bars 3–4 only.
    3. Disable motion playback and compare.
    4. 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.

    1. Pick one clock boss (often TR-8S or laptop).
    2. Disable USB clock if DIN clock is already active (or vice versa).
    3. Slave TB-3 / Boutique / MX-1 as needed; verify MIDI thru paths.
    4. 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.

    1. Program the accent+slide skeleton on paper in ●○– notation.
    2. Enter it on TB-03 (or SH-01A seq) with knobs.
    3. Re-enter the same pitches/flags on TB-3 with the touch pad for filter only.
    4. 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.
