A chord-grid instrument for Ableton Live: explore, perform and record harmony in real time — triads, sevenths, ninths, borrowed chords and secondary dominants, all voiced and voice-led.
Tuple lays out every valid chord in your key as a playable grid — always visible, never hidden behind a menu — and lets you place those chords in time on a bar ruler, then write the result to a clip.
Pick a key and a scale: Tuple instantly generates the full grid of diatonic chords, column by column, from degree I to degree VII. Borrowed chords and secondary dominants stay inside the same grid — no wizard, no separate page.
Click a cell (or hit a pad on the Push 2): the chord plays at once, already voiced and voice-led from the previous one. Your hands stay on the music.
Tuple outputs the chord only — every voicing stays a coherent chord you can play with one hand.
Do not rename or move the files shipped alongside the device: the interface loads from the folder. Keep the bundle intact.
Tuple outputs the chord only, leaving the rest of your arrangement on its own tracks — you keep full control of the low register.

In C Major, try the classic I – V – vi – IV:
Then move up one row to switch to sevenths (CM7 · G7 · Am7 · FM7): the grid stacks richness vertically, from simplest to most colorful.
The BORROWED column (far right) adds color and tension without leaving the key: drop a bVII or a V/vi into the middle of a diatonic progression.
Instead of setting KEY/SCALE by hand, put Tuple on a track whose Live scale is already defined, then press SYNC.
Inside Live's rack, Tuple sits in a compact strip: controls on the left, Monitor on the right. The full grid opens in a second window.
The same device, unfolded: one bar of controls, the whole grid, and the progression drawer underneath.
One hardware-style bar: KEY · SCALE · SYNC, then VOICING · LEADING · SMART · EXPRESSION · OCTAVE, then PUSH and SETTINGS. Everything that shapes the chord is one press away; EXPRESSION opens its panel of faders (Strum, Ramp, Curve, Humanize).
Every valid chord for the key, color-coded by degree: seven columns I–VII plus a Borrowed column. The screen at the bottom carries the progression — ruler, cards, commands and status line, always visible — and the Monitor lives on it.
The SETTINGS plate holds the once-in-a-while switches: LAYOUT, ♭/♯, EXT, AVOID NOTES, ALWAYS ON TOP and THEME — Tuple ships in its Night look, one press for Day — plus ABOUT and the manual. The window itself is resizable: the whole face scales as one, nothing reflows or truncates.
One click on OPEN unfolds the whole grid: seven degree columns and the BORROWED column. Nothing shares the space with them — the controls are on the bar above, the progression on the screen below.
Ten cells, four groups, one row. Every one of them carries its own label, so nothing here needs to be memorised — this page only says what each one changes.
| Cell | What it changes | Chapter |
|---|---|---|
| Key | The root the whole grid is built from. | 04 |
| Scale | The mode. Changing it rebuilds every column at once. | 04 |
| Sync | Imports key and scale from Live's own scale setting. The lamp stays lit while it follows. | 04 |
| Voicing | Chord spacing — six styles, from Closed to Default. | 09 |
| Leading | Voice leading: Off, Anchor, Follow. | 05 |
| Smart | Suggestions: Off, Function, Voice-leading. It is a cycler, not a switch. | 08 |
| Expression | Opens the panel: Strum, Ramp, Curve, Humanize. Also sent out as CC 20–23. | 05 |
| Octave | Shifts the whole chord, −2 to +2. | 05 |
| Push | Grabs the Push 2 pad grid. The lamp says whether it holds it. | 13 |
| System | Opens SETTINGS — the switches you set once and forget. | — |
| Switch | What it does |
|---|---|
| Layout | The degree colour logic: Spectrum, Function, Tension, Fifths, Quality. Ch. 7 |
| ♭/♯ | Flat or sharp spelling for every name on the grid. |
| EXT | Extended: enriches the borrowed chords from what you play. The diatonic grid never changes. Ch. 6 |
| Avoid notes | Filters the tensions that clash with the chord. Switchable, because some styles want them. |
| Always on top | Keeps the full window above Live. |
| Theme | Night or Day. Tuple opens in Night; this manual is shot in Day. |
| About | Version, links, and the update panel when a new build is out. Ch. 15 |
Everything that shapes a chord lives on the bar, in the open. SETTINGS only holds what you decide once: how the grid is coloured, how notes are spelled, which window sits on top.
The Tonality section defines the harmonic world: the whole grid is recomputed the moment you change root or scale.
Choose one of the twelve chromatic roots, from C to B. This is the tonal center the degrees I–VII are built around.
The scale sets the color of the degrees and the available chords:
| Scale | Character | Typical degree I |
|---|---|---|
| Major | Bright, stable — the tonal reference | I maj |
| Minor | Dark, natural minor (Aeolian) | i m |
| Dorian | Minor with a major sixth — jazz, modal | i m |
| Phrygian | Tense minor, minor second — Spanish color | i m |
| Lydian | Dreamy major, augmented fourth | I maj |
| Mixolydian | Major with a minor seventh — groove, blues | I 7 |
| Harmonic Minor | Dramatic minor, raised leading tone | i m |
| Melodic Minor | Minor with a raised 6th & 7th — jazz minor | i m |
| Locrian | Diminished tonic, ♭2 & ♭5 — unstable, dark | i° |
| Lydian Dominant | Lydian with a ♭7 — the ♯11 dominant color | I 7 |
| Major Pentatonic | Five notes, no semitone tension — open | I maj |
| Minor Pentatonic | Five-note minor — riffs, blues, lo-fi | i m |
Why these? They cover the everyday major and minor modes plus the jazz minors and the two pentatonics. For colors outside any scale, reach for the borrowed chords in the grid — secondary dominants and modal interchange, always one click away.
On load, Tuple imports Live's key & scale automatically — the grid starts matched to your project, nothing to set up.
The SYNC button re-imports the key and scale set in Live on demand — handy after you change the key mid-session. If you then change KEY or SCALE by hand, Tuple unsyncs from Live until the next click on SYNC.
The ♭/# switch, in SETTINGS, moves all chord names between flat and sharp notation — grid, screen and menus update at once. The preference is saved and restored across sessions.
| ♭ (flat) | E♭, A♭, B♭ — common in jazz, pop, brass arrangements. |
| # (sharp) | D#, G#, A# — common in guitar-centric contexts. |
Set the scale in Live once, then sync all your Tuple devices to it. Change the key in Live and re-sync to transpose a whole session.
SYNC is one of the six keys on the compact strip — no need to open the full window to re-import Live's scale. Notation, being a set-once choice, lives in SETTINGS in the full window.
Four settings, in this order: the register, then how the notes are spread, then how they move from one chord to the next.
Transposes the whole chord, from −2 to +2 octaves. The cell reads ‹ 0 ›: click an arrow to step, or scroll on the cell. Handy to seat chords in the right register within your arrangement.
Defines how the chord's notes are spread across the register. The menu holds six spacings — Default, Closed, Open, Section, Chord Melody and Two Hands — each described in the voicing reference. Default is the neutral one: no voicing at all, every chord tone at its default position, and voice leading never moves it.
Every spacing is playable with one hand, root included. Only Two Hands is deliberately two-handed (low root + right-hand chord).
The EXT switch, in SETTINGS, enriches the borrowed chords from what you play: Borrowed and Mediants take the extension that fits after your last chord, and tritone subs become 7♯11. The diatonic grid never changes — for the 9ths, 11ths and 13ths of a degree, open the Ext page of the Borrowed column. Turn it off for the plain borrowed chords. Ch. 6
When on, Voice Leading pulls each new chord close to the previous one: the voices move as little as possible, so transitions become smooth and musical instead of jumpy.
| Off | Chords stay exactly as the voicing built them. |
| Anchor | Anchors the voices around a fixed register — stable and predictable. |
| Follow | Minimal movement from the previous chord — the smoothest, most legato. |
For legato pads, set VOICE LEADING to Follow. For repeated rhythmic stabs, set it to Off so every chord lands in the same place each time.
Voice leading reshapes five of the six. Default is the exception: it produces a single candidate, so there is nothing for Anchor or Follow to choose between — measured, it stays put on all 91 cells while Closed moves on 88 of them under Anchor. That is what makes it a neutral reference rather than a style.
The full window adds four performance controls. Drag or scroll each; center / 0 = off.
| Strum | Spreads the chord over time. Left = down (high→low), right = up (low→high); larger values turn the chord into an arpeggio. | ±250 ms |
| Curve | Shape of the strum spacing: Linear, Accelerate or Decelerate. | 3 shapes |
| Ramp | Velocity ramp across the strummed notes. Left = fade (first note loudest), right = build. | ±100 |
| Humanize | Subtle, random velocity & timing variation for a less mechanical feel. | 0 = off |
Each control also goes out as a MIDI controller when you move it — CC 20 Strum, CC 21 Ramp, CC 22 Curve, CC 23 Humanize (bipolar controls sit at 64 when centred). Map them in the instrument after Tuple, or record them: they are sent on change only, never on load.
Vel Min and Vel Max — two Live parameters (1–127, in the device’s automation list) clamp Tuple’s output velocity at the very end of the chain, after Ramp and Humanize. The defaults, 1 and 127, leave the sound untouched.
Voice Leading is the craft of moving between chords with the least motion: keep the notes two chords share in place, and let the rest step to the nearest note instead of jumping. It makes a progression sound connected and legato rather than blocky — and Tuple applies it automatically, re-laying each chord to sit close to the one before.
Each chord plays in root position, in a fixed register. The whole hand jumps from one chord to the next — fine for rhythmic stabs, but disconnected for sustained parts.
The target chord is rearranged to sit near the previous one — shared notes hold, the rest glide by a step. The fingers barely move and the progression flows. One control, three positions, read left to right as manual → automatic: Off leaves the voicing untouched, Anchor keeps a stable register, Follow chases the smoothest path (Ch. 5).
Voice Leading doesn't change which chord you play — only how it's laid out. The harmonic function stays identical; what changes is the smoothness of the transition.
Tuple's principle: show the maximum number of valid chords for the chosen scale, and keep borrowed chords inside the same grid.
Each column is a degree of the scale, named by its function:
| I | Tonic — rest |
| II | Supertonic |
| III | Mediant |
| IV | Subdominant — the lift |
| V | Dominant — the tension |
| VI | Submediant — the relative |
| VII | Leading tone — instability |
The rows stack the degree's chord families, from triad to extensions. A column stops where the scale no longer yields a valid chord — hence the uneven column heights.
The last column gathers borrowed chords (modal interchange) and secondary dominants — colors from elsewhere that enrich the key without leaving it.
| In major | Role |
|---|---|
| ♭III ♭VI ♭VII | Borrowed from the parallel minor |
| iv | Minor subdominant |
| V/V V/ii V/vi | Secondary dominants |
A minor iv right before returning to the I is one of the most moving borrowings in pop.
The column header holds four small screens, one per page: ♭ (Borrowed, the table above), TRI (Tritone), MED (Mediants, chromatic mediants) and EXT (Ext). The page you are on glows violet; click any other screen to switch straight to that page. MED exists in major and minor only: in other scales it stays in place, dimmed, and does nothing when clicked.
Tritone follows your playing: after each chord, it offers tritone substitutes (a dominant seventh a half step above the target) leading to the chords most likely to come next, ranked like Smart. Each cell names its target — D♭7 → C, always first before you play. A sub counts as its target: after D♭7 the page reads as after C, and never offers the sub you just played. Ext shows what the column of the last diatonic chord you played does not have: on the ii of C major, Dm11 D7sus4 D6sus2 Dmadd11…, from your scale, minus avoid notes, closest first. When nothing is new, the page stays empty. Both work in every scale. With EXT on, each sub becomes a 7♯11; Ext stays the same, since EXT never touches the grid it completes.
With EXT on, Borrowed and Mediants follow your playing too. The chords stay the same — same roots, same qualities, same order — but each one takes the extension that fits after the chord you just played: a new color the previous chord did not already have, one note richer, sevenths after sevenths and sixths/add chords after triads. In C major, after C the iv reads Fm6; after Dm7 it reads Fm9. The cell you just played keeps its name while you hold it; the others move. A captured card keeps exactly what you heard. Changing key or scale starts again from the tonic. With EXT off, the column shows the plain chords, as before.
If you change scale while on Mediants, the column falls back to page 1 on its own. The page is also a Live parameter (Borrowed Page) — automatable and saved with your set.
The LAYOUT switch, in SETTINGS, opens a plate of five color logics — or scroll on it to cycle. The grid stays the same; only the way you read it changes.
| Logic | What the color encodes | Use it to… |
|---|---|---|
| Spectrum | A distinct hue per degree, rainbow-style (the bar above). | spot the column instantly. |
| Function | tonic · subdominant · dominant. | think in tension/rest. |
| Tension | home → tense, by dissonance. | pace the color of a progression. |
| Fifths | near → far on the circle of fifths. | compose by fifth motion. |
| Quality | major · minor · dim · aug. | sort chords by type. |
In every logic, borrowed chords stay violet.
Start in Spectrum to memorize where the degrees are, then switch to Function once you think in tonic / subdominant / dominant.
Turn SMART on and, as you play, Tuple lights up the chords that follow naturally from the one you just played. It’s a guide laid over the grid — every chord stays playable; nothing is hidden or forced.
The hue is always the degree color of your current Layout, so the grid still reads the same. The brightness carries the suggestion: brighter = stronger. Empty cells stay dark, and the chord you just played stays highlighted as the anchor.
| Mode | What brightness means | Use it to… |
|---|---|---|
| Function | Harmonic strength — how strongly a chord wants to follow, by function (resolutions, dominants, set-ups, surprises, color). | find the convincing next move. |
| Voice leading | Smoothness — how little the notes move to get there, measured on your current voicing & octave. | keep the motion seamless. |
The SMART button cycles Off → Function → Voice leading. Suggestions are grouped by harmonic function, so you always see a spread of options — a few resolutions, a few tension moves, a few colors — never a whole row lit at once.
Smart works in any Layout — it’s a mode, not a color scheme. And because Voice leading reads your actual voicing, changing the Voicing re-ranks the suggestions: the same progression can light up differently in Closed vs. Open.
The voicing decides how a chord's notes are spread across the register. There are six, and they read as one axis — from no voicing at all to the widest grip. Every one is playable with one hand, root included; only Two Hands is deliberately two-handed.
| Spacing | What it does |
|---|---|
| Default | No voicing at all: every chord tone at its default position, in order — root, 3rd, 5th, 7th, then the extensions. Voice leading never moves it, so it is the reference to compare the others against. |
| Closed | True close position: from the bass up, each note sits as low as it can above the one before. No chord tone can slip into a gap. |
| Open | The root stays at the bottom and the chord opens just above it. Air between the voices, clarity for pads. |
| Section | Drop 2 — the horn-section voicing. The second voice from the top drops an octave: the muddy middle clears and the top note gets air. |
| Chord Melody | Drop 3 — the solo-guitar voicing. The third voice from the top drops instead. Needs four notes; on a triad the cell falls back to Section. |
| Two Hands | The bass note alone, the rest of the chord about an octave above it. The only one that asks for two hands, and the only one that reaches below C3. |
Tuple plays the chord, not a bass part. No spacing drops a voice below the chord to fake a bassline — that is doubling, not voicing, and it belongs on its own track. Two Hands is the documented exception, and it still keeps its floor at C2.
Tuple used to ship twenty-nine voicings: the six above, plus twenty-three genre grips — House, Trance, Funk, Jazz, the Rootless family, Quartal, Soul, Rave and the rest. They were removed in v1.5.0. Here is what that means for a set you already have.
Voice Spacing is the Live parameter that holds the style: six positions, from Closed to Default, automatable and MIDI-mappable. v1.5.0 also kept the old Voicing parameter, with all twenty-nine of its entries, so that an old set could reopen on the nearest surviving spacing. That bridge is gone now.
Open the set, listen, and pick the spacing that fits. Default plays exactly what Closed played before v1.5.0 — note for note, measured — so it is the closest thing to the old default.
Each column stacks these families, in the priority order below. The engine only shows a family when the scale makes it valid for that degree.
| Family | Example labels | Description |
|---|---|---|
| Triad | maj · m · dim · aug | The three-note chord — always available. |
| Seventh | M7 · m7 · 7 · dim7 · ø7 | Adds the 7th — depth and direction. |
| Ninth | M9 · m9 · 9 | Extends to the major 9th. |
| Sixth | 6 · m6 | Soft color, without seventh tension. |
| Add9 | add9 · madd9 | Triad + 9th, no 7th — bright. |
| Sus4 | sus4 · 7sus4 | Fourth instead of the third — suspension. |
| Sus2 | sus2 | Second instead of the third — open. |
| Six/Nine | 6/9 · m6/9 | Sixth + ninth — rich and stable. |
| mMaj7 | mMaj7 | Minor with major 7th — dramatic color. |
| 7♭9 / 7♯9 | 7b9 · 7#9 | Altered dominants — strong tension. |
Tuple detects the real quality of each chord from the scale: the same degree will sound M7, m7 or 7 depending on context, automatically.
The Monitor lives on the screen — the strip’s screen in the rack, the progression screen in the full window. It shows the notes of the current chord in real time (in gold) and highlights them on a mini-keyboard. It's instant visual feedback — useful to learn voicings or check the register.
It also reacts before you play: highlight or hover a chord cell in the grid and the Monitor previews that cell's notes, so you can read a chord with your eyes before committing it.
Tuple splits performance into two surfaces:
The grid is never shrunk: the rack's limited height would hide it, so it lives in its own window — full access stays immediate.
Keep the grid window in front while you work in Live: enable ALWAYS ON TOP in SETTINGS. The window is resizable — the whole face scales as one, so nothing reflows or truncates at any size.
Grid window "always on top" on one side of the screen, Live underneath: you compose at the grid while keeping the arrangement visible.
Stack chords into a progression inside Tuple, then write the whole thing straight to a MIDI clip — no re-playing your chords into a record track.
In the full window, the bottom of Tuple is a hardware-style screen: a bar ruler, your chords as cards on it, a command row in LCD language, and a status line. It is always on.
You can also drag a chord straight from the grid onto the ruler, capture on or off. Next to CAPTURE, PLAY and STOP drive Live’s transport; while Live plays, an amber playhead runs across the ruler and the cards — and the progression sounds: Tuple plays the card under the playhead, no clip needed; gaps are silences.
The ruler is the loop: LOOP ◂ 8 ▸ in the command row sets it from 1 to 8 bars, and the clip follows. Cards sit anywhere on it, to the quarter-bar: drag a card to move it, drag its right edge to set its length, its left edge to set where it starts. Empty ruler is silence — rests are part of the writing. A card dropped onto another cuts what it covers. Click an empty bar to place the insertion cursor.
ctrl-click adds or removes a card from the selection, shift-click takes the range. Drag any selected card and the whole group moves, gaps preserved; hold ctrl as you drop and the group is duplicated there instead. The drag ghost shows every card of the group, exactly where it will land.
A page is one loop. The song is up to 4 pages, written into the clip end to end; PAGE ‹ 1/2 › in the status line turns them, capture opens the next page when the current one is full, and the view follows the playhead while Live plays. A page holds as many chords as its bars have room for — cards go down to a quarter-bar, so space is the only limit.
Click a card to select it: the inspector row shows its numeral and name, and every per-chord control.
The AVOID NOTES switch (in SETTINGS) is what greys the clashing tensions; turn it off and every in-scale color is offered.
The command row carries the clip controls, in LCD language. Pick the destination with the Clip Target control (a Live parameter too): Session writes at the highlighted clip slot, Arrangement writes at the playhead position. Then press CREATE CLIP: on an empty spot, Tuple creates the clip and writes the whole progression — every page, end to end. Where a clip already sits, the button reads APPLY TO CLIP instead, and writes into that one. The two gestures are separate on purpose: nothing is ever replaced by a button that meant “create”.
The clip Tuple just made is now the one it edits. Every change to the progression — add, re-order, remove, re-voice, invert, resize — is rewritten into it as you work. The bar under the buttons names it, next to a 🔗; × detach stops the editing and leaves the clip in Live exactly as it is.
Follow clip — turn the switch on and the clip you select in Live becomes the one the progression edits; click another clip and Tuple follows. Attaching alone changes nothing: the first time your edit would write into a clip Tuple did not create, the bar asks Replace? once. Answer it and that clip is yours — Tuple keeps writing to it without asking again. Leave it unanswered and nothing is written. Nothing you made is ever overwritten silently.
Each card stores the chord exactly as you captured it — already voiced and voice-led — so the clip sounds like what you heard. Change KEY or SCALE and the whole progression follows — names, numerals and notes are re-derived in the new key. Your STRUM, RAMP, CURVE and HUMANIZE settings are written into the clip too — deterministically, so editing one card never re-rolls the feel of the others. All four at zero gives clean block chords.
And when you launch the linked clip, it becomes the only voice: Tuple passes its notes through untouched and its own playback stays silent — stop the clip and the cards take over again.
Writing to an Ableton clip needs Live, so CREATE CLIP and Follow clip are device-only. You can still build, re-order and audition progressions in the browser demo (there it exports a MIDI file instead).
With a Push 2, play the chord grid straight on the pads — one chord per pad, the colors mirroring the screen.
Push extends the grid, it doesn't replace it: columns = degrees I–VII + Borrowed, rows = chord families.
A pressed pad lights up brighter while held. Tuple exposes 13 controls as Live parameters — Octave, Voicing, Voice Spacing, Voice Leading, VL Mode, Strum, Strum Ramp, Humanize, Layout, Capture, Write Clip, Clip Target and Borrowed Page — MIDI-mappable (Cmd/Ctrl+M), automatable, saved with your set. Push is optional; everything works via the mouse too.
Press PROG and the Push becomes a progression companion: the bottom row holds your progression, and the rows above develop the step you select — substitutes, what comes next, or a fresh voicing.
The bottom row is your progression, one chord per pad, left to right. Select a step and the column above it fills with options for that step — a blank row separates the progression from the options. Every step keeps its own column, so you read each one straight up.
| Substitutes | Chords that can replace the step at the same harmonic slot — function siblings (I ↔ iii ↔ vi…) and quality variants. |
| Suite | Where to go next — the same Smart suggestions, offered as a chord to follow this one. |
| Voicings | Every voicing the engine can produce, to re-voice this step in place. |
With CAPTURE on, picking an option edits the progression: Substitutes and Voicings replace the step, Suite inserts a new step after it. With Capture off, the options simply audition — you hear them without changing anything.
Options start neutral; a pad takes its chord’s degree color the moment you press it, so you always see what you’re about to commit.
For a fixed progression, the linked clip is the fastest route: build your chords as cards and let Progression → Clip (Ch. 12) write and rewrite the clip as you edit — voicing, order, duration and expression stay editable after the fact. To capture a free live performance instead, record Tuple’s output onto a second track, as follows.
To capture a free performance (especially on Push), record Tuple’s MIDI output onto a second track: add a MIDI track, set MIDI From to Tuple’s track / Post FX, set Monitor to In (the step most people miss), arm and record. In Push mode, also set the record track’s MIDI To to No Output so notes aren’t echoed and doubled. For playback, give that track its own instrument and mute Tuple’s.
Click the logo (top-left of the window) — it carries a small ? hint — to open the About panel. It shows the current version, creator contact, Discord and website links, and a Replay guide tour button to restart the onboarding overlay.
When Tuple detects a newer version on startup, a small pill appears next to the logo: ↑ v1.X.X. Click the logo to switch the About panel to Update mode.
The panel shows the new version number and a brief changelog. Two paths, depending on the release:
Later dismisses the overlay for the session. Ignore hides this version permanently until the next one.
In-place updates write directly to the Tuple folder next to your .amxd. If you moved the files after installing, use the Download path instead.
The badge simply never appears — the device starts normally. To update manually, download the latest zip from tuple.live and replace the Tuple folder.
| No sound | Tuple must be before the instrument, track armed. |
| Blank interface | Files moved — keep the folder intact, reload the device. |
| Sync does nothing | Define a scale in Live first, then press SYNC. |
| Chords sound muddy | Raise the Octave, or move to Open — it puts air between the voices. |
| A note won’t stop | Disarm then re-arm the track, or stop the transport. |
| Push pads stay dark | Toggle PUSH in the device; Push 2 must be connected. |
| Several Tuples at once | Fine — each instance is independent. One per track for different keys / voicings. |
Is Tuple a sequencer?
It sequences chords — place them on the ruler, leave silences, loop, write a clip. Not a step or note sequencer: no piano roll, and Live plays the clip.
Do I need a Push 2?
No, it's optional. Everything plays via the mouse or MIDI.
Does it follow my song key?
Yes — Tuple imports Live’s key & scale automatically when it loads.
Can I record what I play?
Yes — Tuple sends real MIDI notes. Arm the track, record, then edit the notes like any MIDI clip.
Are the controls automatable?
Yes — 13 controls are Live parameters: automate them, MIDI-map them, saved with your set.
Privacy (Version checks). Tuple checks for updates by making an unauthenticated GET request to the GitHub API. This reveals your IP address and that Tuple is running — no other data is transmitted.

A quick reference for the words used throughout this manual.
| Diatonic | Chords built only from the notes of the current key & scale. |
| Degree (I–VII) | A chord’s position in the scale, in Roman numerals (I = tonic, V = dominant…). |
| Tonic · Subdominant · Dominant | The three harmonic functions: rest, lift, tension. |
| Borrowed chord | A chord taken from a parallel mode (modal interchange) for color — kept inside the grid. |
| Voicing | How a chord’s notes are arranged and spaced (which note sits on top, the gaps between voices). |
| Voice leading | Moving each voice the smallest distance from one chord to the next, for smooth transitions. |
| Off / Anchor / Follow | The three positions of Tuple’s VOICE LEADING control: untouched, fixed register, minimal movement. |
| Inversion | The same chord with a note other than the root at the bottom. |
| Rootless voicing | A voicing that omits the root, leaving it to the bass instrument. A harmony term: Tuple keeps the root in every spacing, by design. |
| Drop voicing | One inner voice dropped an octave (Drop 2 / Drop 3) for a wider, open sound. |
| Octave | Shifts the whole chord up or down in register. |
| Layout | The color logic used to read the grid (Spectrum, Function, Tension…). |
| Smart Chords | A guide overlay: as you play, the grid lights likely next chords — by function (strength) or voice leading (smoothness). |
| Strum | Spreads a chord’s notes over time (down or up), up to an arpeggio. |
| Humanize | Small random velocity & timing variation for a less mechanical feel. |
| Tension | A color note (9th, 11th or 13th family) stacked above a progression card as an upper structure — the chord underneath keeps its shape. |
| Avoid notes | Tensions the tonal tradition avoids on a given chord type (the 11 on a major chord…). Tuple greys them; the switch in SETTINGS turns the filter off. |
| Page | One loop of the progression screen (1–8 bars). A song is up to four pages, written to the clip end to end. |
