Yes. Interaktiv Tap plays Traktor Pro 3 or 4.

Does it work wirelessly?

Not yet — Interaktiv Tap connects over USB MIDI.

Why USB and not wireless?

USB gives a rock-solid, low-latency connection — exactly what you want on stage, where timing matters and a dropped signal mid-set isn't an option.

Does it replace my controller?

No. The mapping installs as its own device in Traktor’s Controller Manager, so your S4, X1 or hand-built mappings stay exactly as they are and everything can be connected at the same time. Freeze snapshots Traktor itself, so restoring also brings back what your other controllers set — for every function Interaktiv Tap maps.

Does everything work on Traktor Pro 3?

Yes. Everything Interaktiv Tap plays behaves the same on Pro 3 and Pro 4 — the full effect list, all four deck types, and the settings merge. Nothing on the surface is greyed out on 3.

Does it work on Windows?

Yes — the iPad appears to a PC as a standard MIDI device the same way it does to a Mac. The written setup guide is macOS-only so far, so if you are on Windows, ask us and we will walk you through it.

I have never opened Traktor’s settings. Can I do this myself?

Yes, and you never build a mapping by hand. In Traktor, Preferences → Export writes a file of your own settings. The app then shows you a web address: open it in a browser on the same computer and drop that file onto the page. The app folds its mapping into your settings and the merged file downloads straight back. Then Preferences → Import that file, keeping every box ticked. Nothing is emailed and nothing is typed. It takes about two minutes the first time.

Which cable do I need?

Whatever cable came with your iPad — Lightning or USB-C — straight into the computer. No camera adapter; the direct connection is the one that works.

Does the iPad stay charged during a set?

It charges over the same USB cable that carries the MIDI.

Can I beatmatch by ear? Is there a tempo fader?

There is a master tempo fader in the header — the surface is built around Traktor’s sync, so you ride the master tempo and nudge a deck’s phase with Tempo Bend. Individual deck tempo faders are not on the surface.

Anything to set on the iPad before a gig?

Turn on Do Not Disturb or a Focus so notifications don’t land mid-set. The app keeps the screen awake while you play, so there is nothing else to change.

How much latency does it add?

None you can feel. The full round trip — your touch out to Traktor and Traktor’s answer back to the iPad — runs in under 8 ms, less than one frame at 120 Hz. What you hear is Traktor’s own audio buffer, exactly as with any controller.

Can I change the layout?

Not as a supported feature, and that is deliberate. Interaktiv Tap ships tuned, the way an instrument does — a CDJ or an F1 arrives the way it arrives, and the two-way feedback here depends on the mapping being designed as a whole. If you would rather build your own surface, TouchOSC is very good at exactly that; it is a different craft. If something here is missing or in the wrong place, tell us — feature requests are welcome.

How much does it cost?

Interaktiv Tap is free to download and free to play in 15-minute demo sessions. Unlocking everything is a one-time purchase — $14.99 in the US, shown in your own currency on the App Store. There is also a 7-day free trial of everything. No subscription.

Is it a subscription?

No. One-time purchase — buy once, own it.

Is there a free trial?

Yes — a 7-day free trial of everything, offered when a demo session ends and any time from Settings → Purchase. Even without it, the app is free to play in 15-minute demo sessions; one purchase removes the limit.

What happens when the trial ends?

The app switches to demo sessions: everything still works, and a session pauses after 15 minutes. Relaunch the app to start a new one, or unlock once to remove the limit.

I bought Interaktiv Tap when it was a paid app — do I pay again?

No. Your original purchase covers everything in version 1. The app unlocks automatically from your App Store receipt; if it doesn’t show at once, relaunch while online or tap Restore Purchase.

Any iPad that runs iPadOS 18 or later, apart from the mini. By model: iPad 7th generation (2019) and later; iPad Air 3rd generation (2019) and later, in both the 11-inch and 13-inch sizes; iPad Pro 11-inch, every generation; and iPad Pro 12.9-inch 3rd generation (2018) and later, including the 13-inch. Older ones cannot reach iPadOS 18 — that rules out the iPad 6th generation and earlier, the iPad Air 1st and 2nd, the iPad Pro 9.7-inch and 10.5-inch, and the first two 12.9-inch Pros. Not sure which you have? Settings → General → About shows the model name. The mini runs the app, but its layout is not tuned yet.

Does it run on iPhone or Mac?

Not iPhone — the layout needs an iPad-sized screen. Mac, yes: on Apple Silicon it installs from the App Store as an iPad app, and it can even control Traktor on the same machine — in Traktor’s Controller Manager, set the device’s in-port to RTP Session 1 (the Mac’s network MIDI session — pick that specific port, not All Ports). Treat that as exploration, not performance: latency is higher than over USB, and macOS gives you one pointer — even an attached touchscreen acts as a mouse, one finger at a time. The instrument is an iPad and one USB cable.

Does it run on Android?

No — Interaktiv Tap is an iPad app.

How do I get the Traktor mapping?

Through your own Traktor settings file. Export it from Traktor with every box ticked, open the address the app shows in your Mac’s browser, and drop the file on that page — the merged copy downloads straight back with the mapping folded in. Import it in Traktor, every box ticked. (AirDropping the file to the app works too.) Your other controllers and preferences survive. Repeat after every app update.

Standard MIDI — CC and notes.

Can I load tracks or samples in the app?

Not yet. Browsing and loading stay in Traktor today — you load tracks and build Remix sets there, and the iPad fires the cues, loops, and cells that are already there.

INTERAKTIV AUDIO LIMITED — a two-person studio: Andrey Koppel (software) and Pierantonio Gualtieri (sound).

Does the app collect my data?

No. Interaktiv Tap runs entirely on your iPad — no account, no analytics, no tracking.

Refunds for App Store purchases are handled by Apple, through your purchase history.

Can my family use my purchase?

Yes — one purchase works on all your own devices and shares with your family at no extra cost via Apple’s Family Sharing. The 7-day trial itself is per person.

What Interaktiv Tap is

Interaktiv Tap is a multi-touch instrument for iPad: you play your set with gestures, not knobs and jog wheels. It plays Traktor Pro 3 or 4 over USB MIDI — full decks, the mixer, EQ and kills, FX, loops, and recorded gestures, in sync both ways. It’s purpose-built and ready to play, not a blank MIDI template you set up yourself. It’s free to download and free to play in 15-minute demo sessions, with an optional 7-day free trial of everything and a one-time unlock — no subscription.

Requirements

iPad
Any iPad running iPadOS 18 or later, except the mini — see “Which iPads work?” below for the models. The mini runs it, but that layout is not tuned yet
Traktor Pro 3 or 4 on a Mac or PC
One cable, Lightning or USB-C, straight into the computer — no camera adapter

The iPad appears to the computer as a standard MIDI device. There is no wireless mode — the link is USB. The setup guide is written for macOS; Windows works the same way, but that guide isn’t written yet — ask and we’ll help.

Get started

The app walks you through this on first launch — a setup wizard that ticks each step off by itself as it detects your Mac, and it comes back on every launch until setup is done. Here is the same path in writing:

Install Traktor Pro 3 or 4 on your Mac.
Connect the iPad to the Mac with a USB cable.
On the Mac, open Audio MIDI Setup and click Enable for the iPad, so it appears as a MIDI device.
In Traktor: Preferences → Export. Tick every box and save the file — this is your own settings backup, and it is what the app merges into.
On the Mac, open the address the app’s setup screen shows in a browser, and drop the exported file anywhere on that page. The app folds its mapping into your settings — everything you had stays as it was — and the merged copy downloads straight back to the Mac. (No shared Wi-Fi? AirDrop the file to the iPad and choose Interaktiv Tap, then AirDrop the merged file back.)
In Traktor: Preferences → Import, choose the merged file, and keep every box ticked. This is how the Interaktiv Tap mapping gets into Traktor — along with a new four-deck “Interaktiv Tap” layout, the four-band EQ, four FX units, and the pinned effect list.
In Controller Manager, check that the In-Port and Out-Port show iPad — the import usually sets them for you.
Play. Traktor announces itself the moment the ports are set — the app confirms the connection, and the iPad plays Traktor in sync both ways.
One habit to keep: after every app update, repeat the export → merge → import round trip. Updates can extend the mapping and the effect list, and Traktor needs the fresh file to match the app.

Set up Traktor

Importing the merged file sets all of this for you — it carries these preferences alongside the mapping. Here is what it changes, and where each one lives if you ever want to check or set it by hand:

Four decks: Interaktiv Tap plays four decks, so Traktor needs all four. The merged file adds a new layout called “Interaktiv Tap” to your Layout Manager — four decks with the FX panels on screen, laid out for playing from the iPad — and opens Traktor on it. Your own layouts are left exactly as they were, one click away in Traktor’s layout menu. If your export didn’t include the GUI layouts, the app says so; then switch decks on yourself under Preferences → Decks → Show Deck C & D, and show the FX panels via the Global Section (Effect 1 / Effect 2).
Four-band EQ: Preferences → Mixer → EQ Type → Xone. This gives the four-band EQ the app’s EQ page maps to — HIGH, MID H, MID L, LOW, each with a kill.
Four FX units: Preferences → Effects → 4 FX Units, so each of the app’s FX quadrants has a unit to drive. The four FX panels are set to Single mode at the same time.
MIDI clock: Preferences → External Sync → Enable MIDI Clock. Traktor sends its clock to the iPad, which is what keeps the gesture recorder and the Loop Recorder in time. It’s off in a stock Traktor, so the merged file switches it on. Tap SYNC in the app’s header to fire the clock at the start of a set.
FX pre-selection: The merged file pins the full effect list the FX units step through, in a fixed order, so the on-screen names match. It replaces any effect pre-selection you curated in Traktor — your export is your backup if you want the old list back. Which of those effects each FX unit actually offers is curated per unit in the app.
Mixer FX slots (your choice): Preferences → Mixer → Mixer FX. This one stays yours: the four slots set the effects behind the app’s filter / Mixer-FX fader. They’re shared across every deck; choose what each one is, and its colour matches in Traktor and in the app.

Merging with your Traktor settings

The merged file is how the Interaktiv Tap mapping gets into Traktor. You export your own Traktor settings, the app folds its mapping and preferences into that file, and you import the result — so Traktor gets Interaktiv Tap without giving anything up. The round trip usually runs through your Mac’s browser: the app shows an address, you drop the export on that page, and the merged copy downloads straight back (AirDropping the file to the app works too). That page is served by the iPad itself, so the file never leaves your own network. Your export is never modified either — the merged copy arrives as a separate file, so the original stays on your disk and you can always go back to it. Tick every box on the way out and on the way back in: Traktor’s import replaces whole categories, so a file that only holds part of your setup imports only that part. This matters most for controller mappings, because Traktor keeps every controller in one block — importing a file that contains only one mapping leaves you with only that mapping, and any other gear you had set up is gone from Controller Manager. Merging is what avoids this: your other controllers travel inside the same file and come back untouched. Nothing you already had is rewritten: your other controllers travel back untouched, and the four-deck setup arrives as a NEW “Interaktiv Tap” layout beside your own rather than as a change to them. The app tells you what it found — how many other controllers it kept, whether it replaced an older copy of its own mapping, and whether it could add the layout. The file also carries the mapping’s port assignment, so after the import the In-Port and Out-Port usually show iPad by themselves. If it reports no other controllers on a Traktor that definitely has some, your export was missing them: export again with every box ticked and merge that file instead. And if a past import already emptied your Controller Manager, you can rebuild it: import the merged file first, then add your other mappings back with Controller Manager → Import Other… , which adds a device without touching the ones already there.

iPad settings (optional)

Two optional iPad settings make the surface feel better — nice to have, not required:

Full-screen, not windowed: Settings → Multitasking & Gestures → Full Screen Apps (rather than Windowed Apps or Stage Manager). It stops iPadOS from treating taps near the top edge as window resize or move, so the top row stays reliable.
Free up all ten fingers: On the same page, turn off Four & Five Finger App Switching so iPadOS doesn’t intercept multi-finger gestures — leaving all ten fingers for the surface.

Reading the screen

The screen is a 2×2 grid of quadrants, at positions A (top-left), B (top-right), C (bottom-left), and D (bottom-right). Each quadrant is either a deck or an FX unit, and carries a label — like TRACK C, REMIX A, or LIVE B — so you always know what you are touching.

The gestures

Interaktiv Tap uses a small set of multi-touch gestures so the surface stays uncluttered:

Single tap: Works the small single-cell buttons and the launch cells.
Two-finger tap: The bigger buttons — anything two cells wide or more — so you can’t fire play, switch a quadrant, or save a snapshot by accident.
One-finger press-and-hold: Reveals a button’s extra options for as long as you hold.
Two-finger press-and-hold: Opens a picker — or, on FREEZE, locks the app.
One-finger swipe: Expands or collapses a deck.

Hold to reveal more

If a control isn’t on the screen, it’s usually one hold away. Hold a button with one finger and its extra options appear for as long as you hold. The deck name button is the main one — depending on the page it reveals the page switches, the KEY lock, the Mixer-FX on/off, the headphone cue, and more. LOOP, SYNC, GAIN, and the FX button each reveal their own — loop sizing, tempo-bend nudges, gain on the volume fader, the Mixer-FX slots. On an FX unit, hold SEL to pick effects and SIZE to set a recorded loop’s length. The rule of thumb: if you want something you can’t see, hold.

Decks

Switch a quadrant between a deck and an FX unit

Two-finger tap the quadrant’s name button — the deck name or the “FX UNIT” label on the outer edge. It flips in place, keeping the rest of your layout.

Choose a deck flavor

Press the deck name button with two fingers and hold for about a second. A SELECT DECK picker opens with four choices. Two-finger tap one to switch; two-finger tap the header to cancel.

Track: A standard beatgrid deck — hot cues, loop, transport, key, and EQ.
Stem: Adds per-stem pages for the four stems’ volume, filter, and FX send — hold the deck name to reveal each page’s own per-stem buttons (MUTE on VOL, ON/OFF on FILTER and FX SEND).
Remix: Turns the Home page into a 4×4 cell launcher with four sample pages and per-slot monitor and punch.
Live Input: Passes external audio — an aux, mic, or turntable — through the channel’s EQ and filter.

Switch pages

A deck shows one page at a time. Press and hold the deck name button with one finger — the page buttons appear for as long as you hold, and you tap one to switch to it. The Home page (hot cues, key, transport) is the default — it has no button of its own, so to get back to it you tap the selected page again to deselect it. EQ is the four-band isolator with kills; Stem and Remix decks add VOL, FILTER, and FX SEND. A Track deck has just the EQ page.

Expand and collapse

Swipe the deck name button to expand a deck so it fills its column. Top decks (A and B) expand with a downward swipe; bottom decks (C and D) expand upward. When a deck expands, its column-neighbour shrinks to a single-row strip pinned to the top or bottom edge, keeping the essentials — volume, play, cue, meters. To go back to two equal decks, swipe the expanded deck’s name button the other way, or swipe that strip’s name button back toward its edge. Collapsing a deck returns it to its Home page. Live Input decks do not expand.

Performing

The Home page

The Home page is the deck’s default view — there’s no button for it; you return to it by deselecting whatever page is selected. On Track and Stem decks it shows eight hot cues, a horizontal KEY fader (tap above or below center to nudge a semitone, double-tap to reset), and a transport row. Two-finger tap PLAY to start or stop the deck, and two-finger tap SYNC to lock it to the tempo; hold SYNC to reveal tempo-bend nudges.

Hot cues

The Home page has eight hot cues. Tap a lit cue to jump to it. Tap an empty (dim) cue to set one at the current playhead. A cue’s color shows the type it has in Traktor: Cue (blue), Fade In (orange), Fade Out (red), Load (yellow), Grid (white), Loop (green).

Set a loop

Two-finger tap the LOOP button to start an auto-loop at the current size. To change the size, hold LOOP with one finger — ÷2 (halve) and ×2 (double) buttons appear; tap them to step through 1/32 up to 32 beats. Two-finger tap LOOP again to release the loop. (Live Input decks have no loop.)

Start and stop a deck

Two-finger tap PLAY in the deck’s transport row (Home page) to start the deck; two-finger tap it again to stop. (Two fingers so a stray touch can’t fire it mid-set.)

Sync a deck

Two-finger tap SYNC to lock the deck to the master tempo; two-finger tap again to release. To nudge the timing by hand, hold SYNC with one finger — ‹ and › buttons appear where PLAY was; press and hold ‹ to bend the tempo down or › to bend it up, and let go to stop.

Change the key (pitch)

The KEY fader on the Home page shifts the deck’s pitch. Drag it for a continuous change, or tap just past center to either side to nudge it a semitone — up to ±12. Double-tap to snap back to the original key. Hold the deck name button to reveal a LOCK toggle beside the fader — Traktor’s keylock; with keylock on the KEY fader turns blue, with it off the fader is white.

Remix cells

A Remix deck shows a 4×4 grid of cells. Tap a loaded cell to launch it — if Traktor’s quantize is on it starts in time, snapped to the quantize size you’ve set (a beat, a bar, and so on); otherwise it starts at once. You can stop a cell only while it’s actually playing — tap the playing cell to stop it (and if another cell is queued, that first tap cancels the queue instead). A cell that’s only cued, not yet playing, can’t be stopped — only re-triggered; that’s Traktor’s behavior, not the app’s. Hold the deck name button to reveal the P1–P4 sample pages, each slot’s Monitor and Punch, and the deck’s PLAY and SYNC — which sit in the transport row on Track and Stem decks but live under the hold on a Remix deck. Cells show their state by color — loaded, queued, playing, or stopping.

The mixer

Each channel has a volume fader — hold GAIN to trim gain on the same fader — a four-band EQ with a kill per band, and a filter that doubles as the Mixer FX amount. Hold the deck name to reveal a headphones (PFL) cue button below the volume fader; while cue is on, the volume fader shows a headphones icon.

Kill an EQ band

On the deck’s EQ page, hold the deck name button with one finger — the band faders shrink and each band gets its own KILL button: HIGH, MID H, MID L, LOW. Tap a band’s KILL to drop it; tap again to bring it back. LOW is the bass. (You can also flick a band’s EQ fader hard to center to slam it out — see the slam-juggle.)

Filter & Mixer FX

Each channel has a FLTR fader on its right edge — a center-detent filter. Drag it up for a high-pass (thins out the lows), down for a low-pass (cuts the highs); the center is off. That same fader doubles as the channel’s Mixer FX amount: hold the FX button to reveal the four Mixer-FX slots, tap one to select it, and the fader then drives that effect (its label shows SLOT 1–4). Hold the deck name button to reveal an ON/OFF toggle under the fader that switches the channel’s Mixer FX on or off; with it off, the fader dims.

Cue a deck in your headphones

Hold the deck name button with one finger — an HP (headphones) button appears below the volume fader. Tap it to send that channel to your headphone cue; while it’s on, the volume fader shows a small headphones icon. Tap HP again to turn cue off. On an expanded deck the HP button is always there — no hold needed — in the top-row inner cell, where GAIN sits on a normal deck.

FX units

An FX unit centers on a pad that adapts to the effect: with three live knobs it’s an XYZ pad — the first finger drives X and Y, and a second finger’s distance from the first sets the third axis; with two knobs it’s an XY pad; with one — including the single-knob macro effects, marked with an [M] prefix — it’s a horizontal X strip that works in relative drag, like the faders: touching down never jumps the value, and a full-width drag covers the full range. Put two fingers down one after the other, not together, so the first finger keeps X and Y. Small labels name the axes — the X parameter along the bottom edge, Y stacked on the left, Z on the right; axes the effect doesn’t use stay unlabeled. A dry/wet fader sets the mix.

Hold SEL to choose the effect: the dry/wet fader becomes two buttons — PREV on top, NEXT below — and each press steps through the unit’s list, wrapping at the ends; the on-screen effect name matches Traktor’s. Switching an effect starts it clean: the unit drops to Single mode and its deck routing clears, so re-enable ON and the deck sends (A–D) when you’re ready. Selecting NO EFFECT parks the unit — the pad, dry/wet, and rec row dim and ignore touch until an effect is chosen; SEL, PREV, and NEXT stay live. Hold the FX-UNIT button with one finger to swap the rec row for the effect’s own buttons: RST recalls the effect’s stored snapshot, up to two more effect buttons appear (a dimmed – means the effect has none), and SEL becomes SAVE — press it to store the current settings as the snapshot RST recalls. The buttons stay in step with Traktor. Four routing buttons send decks A, B, C, and D into the unit. Flip an FX unit’s quadrant to a deck and the unit keeps running — the deck’s name button shows that unit’s send routing (the A–D cells) and rings green while its recorded automation is still playing.

Curate an FX unit’s effects

Each FX unit can carry its own short list of effects, so PREV and NEXT step only through the ones you want. Two-finger hold the FX-UNIT button to open SELECT EFFECT. Each row has an ON/OFF toggle and the effect name; turn an effect OFF to skip it in that unit’s PREV/NEXT cycle — it stays available, just hidden. A unit always keeps at least one effect shown, so the last ON toggle won’t turn off. Drag an effect by its name to reorder the list, dragging to the top or bottom edge to scroll further; the scroll fader on the unit’s inner edge moves through the whole catalog. Your choices are per unit and are remembered between sessions. Two-finger tap the SELECT EFFECT header to close.

Faders

All faders use relative drag: touch anywhere on the fader and move — you do not have to grab the handle. EQ, filter, and key faders have a strong catch at center, so neutral is easy to find. Double-tap or two-finger tap a fader to reset it, even mid-move.

The slam-juggle move

On the EQ, filter, and key faders, a fast flick toward the middle latches at exact neutral — so you can slam a band or the filter in and out rhythmically and always land cleanly on center. Pull back out to release it, or lift your finger to cross straight past. A slow, careful move slides through the center instead, so you can still set any value precisely.

Recording & looping

Record a gesture loop

Each FX unit can record what you do on the pad as a loop, into one of two slots. Tap REC to arm and pick a slot, then touch the pad — recording starts the moment you touch (REC disarms), and a marker shows where on the pad you began, so you can return to it before lifting for a seamless loop. As you record, the slot fills once per beat — the beat grid to play against. It captures in beats; when you lift your finger the loop length snaps to the nearest beat, so it’s quantized and always plays back in sync, and the loop starts the instant you release. While a loop is playing, touch the pad and a dimmed green ‘ghost’ marker shows where the recorded loop is driving it — your finger takes over, so you can ride the loop or rejoin it; lift off and the loop drives the pad again. Hold SIZE to halve or double a playing loop’s length. The recorder follows the incoming clock, so start Traktor’s clock first — the SYNC button blinks as a reminder if it isn’t running.

The Loop Recorder

To record audio, use the Loop Recorder in the header: tap REC to capture a phrase, then PLAY to loop it back, and blend it into the mix with the DRY/WET fader. Hold SIZE to set the loop length — 4, 8, 16, or 32 beats. The Undo/Redo button becomes Delete when nothing is recorded. (This loops audio, unlike the FX gesture recorder, which loops a pad move.)

FREEZE & lock

FREEZE lets you play freely and snap back. It captures your performance moves — faders, EQ, filter, loop, key — but not the master tempo or the selected FX, which stay as they are.

Hold with one finger: Snapshots the current sound. Change anything, then release to return to where you were.
Two-finger tap: Saves a snapshot you can come back to hands-free — the button becomes RESET.
Two-finger press-and-hold (about a second): Locks the app so you can wipe or clean the screen without anything responding, while the music keeps playing. Two-finger tap again to unlock.

Staying aware

The header keeps you informed at a glance: the live tempo, channel and FX meters, and a small performance readout so you can see the app is healthy through a long set. The meters are pre-fader and per deck: twin LED strips beside each volume fader show that deck’s left and right level as Traktor hears it before the fader — so a cued track stays visible even with its fader all the way down. They run green, turn yellow as the signal gets hot, and red at the top. Each FX-UNIT button carries the same left/right strip along its bottom edge, and a collapsed deck’s strip keeps its meters. Nothing hides what is going on.

Master tempo & sync

The header carries the set’s master controls. The master tempo strip bends the overall tempo — drag or tap it to nudge Traktor’s clock up or down. Beside it, the SYNC button does two things at once. It sends Traktor’s MIDI clock, so loops, the gesture recorder, and the Loop Recorder run in time — it re-fires the clock even if it was already on, so switch SYNC on before you record. It also asks Traktor for its current state, so the iPad catches up to whatever is already loaded — effect names, hot-cue colors, loop sizes, and the rest of the two-way read-outs settle into place from a single tap. Tap SYNC when you start a set, or after reconnecting the iPad, and the surface matches Traktor from the first gesture. One known limit: while the MIDI clock is already running, Traktor can cut the state dump short — if some read-outs don’t settle, tap SYNC again. (This is the master clock, separate from each deck’s own SYNC.)

Settings

Open Settings from the gear in the top-right corner. So a stray tap can never open it mid-performance, it opens on a deliberate one-second press, not a quick tap. Settings holds the Traktor mapping: Add Interaktiv Tap to your Traktor settings takes your exported Traktor file — dropped on the page at the address it shows, or picked from Files — folds the mapping in, and hands it straight back (the full steps are under Get started; on first launch the setup wizard walks you through them, and it returns on every launch until setup is done). Do this again after every app update, so Traktor’s mapping and effect list match the app. Two more options live here: a text-size slider that enlarges the text in Settings and the in-app manual (the performance surface stays fixed), and Show touch points, which draws a soft ring under each fingertip — handy for screen recordings and screencasts (off by default).

How it talks to Traktor (MIDI)

Interaktiv Tap speaks standard MIDI — CC for continuous moves and notes for the Remix cells. It runs both ways: your moves drive Traktor, and Traktor’s state (play, loop, FX, cue, meters, cell state) echoes back so the iPad always matches. The mapping wires it to Traktor’s commands; it reaches Traktor inside the merged settings file you import once (see Get started).

FAQ

Do I need Traktor?: Yes. Interaktiv Tap plays Traktor Pro 3 or 4.
Does it work wirelessly?: Not yet — Interaktiv Tap connects over USB MIDI.
Why USB and not wireless?: USB gives a rock-solid, low-latency connection — exactly what you want on stage, where timing matters and a dropped signal mid-set isn't an option.
Does it replace my controller?: No. The mapping installs as its own device in Traktor’s Controller Manager, so your S4, X1 or hand-built mappings stay exactly as they are and everything can be connected at the same time. Freeze snapshots Traktor itself, so restoring also brings back what your other controllers set — for every function Interaktiv Tap maps.
Does everything work on Traktor Pro 3?: Yes. Everything Interaktiv Tap plays behaves the same on Pro 3 and Pro 4 — the full effect list, all four deck types, and the settings merge. Nothing on the surface is greyed out on 3.
Does it work on Windows?: Yes — the iPad appears to a PC as a standard MIDI device the same way it does to a Mac. The written setup guide is macOS-only so far, so if you are on Windows, ask us and we will walk you through it.
I have never opened Traktor’s settings. Can I do this myself?: Yes, and you never build a mapping by hand. In Traktor, Preferences → Export writes a file of your own settings. The app then shows you a web address: open it in a browser on the same computer and drop that file onto the page. The app folds its mapping into your settings and the merged file downloads straight back. Then Preferences → Import that file, keeping every box ticked. Nothing is emailed and nothing is typed. It takes about two minutes the first time.
Which cable do I need?: Whatever cable came with your iPad — Lightning or USB-C — straight into the computer. No camera adapter; the direct connection is the one that works.
Does the iPad stay charged during a set?: It charges over the same USB cable that carries the MIDI.
Can I beatmatch by ear? Is there a tempo fader?: There is a master tempo fader in the header — the surface is built around Traktor’s sync, so you ride the master tempo and nudge a deck’s phase with Tempo Bend. Individual deck tempo faders are not on the surface.
Anything to set on the iPad before a gig?: Turn on Do Not Disturb or a Focus so notifications don’t land mid-set. The app keeps the screen awake while you play, so there is nothing else to change.
How much latency does it add?: None you can feel. The full round trip — your touch out to Traktor and Traktor’s answer back to the iPad — runs in under 8 ms, less than one frame at 120 Hz. What you hear is Traktor’s own audio buffer, exactly as with any controller.
Can I change the layout?: Not as a supported feature, and that is deliberate. Interaktiv Tap ships tuned, the way an instrument does — a CDJ or an F1 arrives the way it arrives, and the two-way feedback here depends on the mapping being designed as a whole. If you would rather build your own surface, TouchOSC is very good at exactly that; it is a different craft. If something here is missing or in the wrong place, tell us — feature requests are welcome.
How much does it cost?: Interaktiv Tap is free to download and free to play in 15-minute demo sessions. Unlocking everything is a one-time purchase — $14.99 in the US, shown in your own currency on the App Store. There is also a 7-day free trial of everything. No subscription.
Is it a subscription?: No. One-time purchase — buy once, own it.
Is there a free trial?: Yes — a 7-day free trial of everything, offered when a demo session ends and any time from Settings → Purchase. Even without it, the app is free to play in 15-minute demo sessions; one purchase removes the limit.
What happens when the trial ends?: The app switches to demo sessions: everything still works, and a session pauses after 15 minutes. Relaunch the app to start a new one, or unlock once to remove the limit.
I bought Interaktiv Tap when it was a paid app — do I pay again?: No. Your original purchase covers everything in version 1. The app unlocks automatically from your App Store receipt; if it doesn’t show at once, relaunch while online or tap Restore Purchase.
Which iPads work?: Any iPad that runs iPadOS 18 or later, apart from the mini. By model: iPad 7th generation (2019) and later; iPad Air 3rd generation (2019) and later, in both the 11-inch and 13-inch sizes; iPad Pro 11-inch, every generation; and iPad Pro 12.9-inch 3rd generation (2018) and later, including the 13-inch. Older ones cannot reach iPadOS 18 — that rules out the iPad 6th generation and earlier, the iPad Air 1st and 2nd, the iPad Pro 9.7-inch and 10.5-inch, and the first two 12.9-inch Pros. Not sure which you have? Settings → General → About shows the model name. The mini runs the app, but its layout is not tuned yet.
Does it run on iPhone or Mac?: Not iPhone — the layout needs an iPad-sized screen. Mac, yes: on Apple Silicon it installs from the App Store as an iPad app, and it can even control Traktor on the same machine — in Traktor’s Controller Manager, set the device’s in-port to RTP Session 1 (the Mac’s network MIDI session — pick that specific port, not All Ports). Treat that as exploration, not performance: latency is higher than over USB, and macOS gives you one pointer — even an attached touchscreen acts as a mouse, one finger at a time. The instrument is an iPad and one USB cable.
Does it run on Android?: No — Interaktiv Tap is an iPad app.
How do I get the Traktor mapping?: Through your own Traktor settings file. Export it from Traktor with every box ticked, open the address the app shows in your Mac’s browser, and drop the file on that page — the merged copy downloads straight back with the mapping folded in. Import it in Traktor, every box ticked. (AirDropping the file to the app works too.) Your other controllers and preferences survive. Repeat after every app update.
What does it send?: Standard MIDI — CC and notes.
Can I load tracks or samples in the app?: Not yet. Browsing and loading stay in Traktor today — you load tracks and build Remix sets there, and the iPad fires the cues, loops, and cells that are already there.
Are sample packs available?: Sample packs for Traktor Remix Decks are coming soon.
Who made it?: INTERAKTIV AUDIO LIMITED — a two-person studio: Andrey Koppel (software) and Pierantonio Gualtieri (sound).
Does the app collect my data?: No. Interaktiv Tap runs entirely on your iPad — no account, no analytics, no tracking.
Can I get a refund?: Refunds for App Store purchases are handled by Apple, through your purchase history.
Can my family use my purchase?: Yes — one purchase works on all your own devices and shares with your family at no extra cost via Apple’s Family Sharing. The 7-day trial itself is per person.

Troubleshooting

Why doesn’t Traktor respond to the iPad?: Check the USB cable, confirm the iPad is enabled in Audio MIDI Setup, confirm the merged settings file is imported (Preferences → Import, every box ticked) so Interaktiv Tap appears in Controller Manager, and check that its In-Port and Out-Port are set to iPad — the import usually sets them for you. Note the app only counts Traktor as connected once its own mapping answers, so MIDI from other controllers won’t light it up.
My iPad faders move but nothing happens in Traktor — why?: Open Traktor → Preferences → Controller Manager and confirm the mapping’s device and ports match your iPad.
Why doesn’t the iPad appear as a MIDI device?: On a Mac, open Audio MIDI Setup, find the iPad, and click Enable. Importing the merged file usually sets it as the mapping’s In-Port and Out-Port by itself — check Traktor’s Controller Manager if not.
Where is Settings?: The Settings button is the gear in the top-right corner. It opens on a deliberate one-second press, not a quick tap.
Why is the FX recorder dimmed and won’t record?: The gesture recorder follows the incoming clock. Tap SYNC in the header to start Traktor’s clock, and the recorder becomes active. If nothing arrives, check Traktor → Preferences → External Sync → Enable MIDI Clock — importing the merged settings file switches it on, but a stock Traktor has it off.
Traktor still shows only two decks after importing — how do I get four?: Check Traktor’s layout menu and pick the “Interaktiv Tap” layout — the merged file adds it as a new four-deck layout rather than changing the layouts you already had. If it isn’t in the list, your export didn’t include its GUI layouts (the app tells you when that happens): either export again with every box ticked and merge that file, or switch decks on yourself under Preferences → Decks → Show Deck C & D (and show the FX panels via the Global Section — Effect 1 / Effect 2).
My other controller mappings disappeared from Controller Manager — how do I get them back?: Traktor keeps every controller in one block, so importing a file that holds only one mapping leaves only that one. Recover from your own settings backup: import the merged file first, then re-add each other mapping with Controller Manager → Import Other… , which adds a device without replacing what’s there. To avoid it in future, always merge (the app folds its mapping into your own export, keeping your other gear) and tick every box on export and import.
The app says it couldn’t merge my Traktor file — what now?: Export again from Traktor with every box ticked (Preferences → Export) and merge that file. The app refuses any file it can’t modify safely rather than risk your settings, so the fix is almost always a fresh, complete export. Make sure you’re sending the exported .tsi itself, not a renamed or edited copy.
The address the app shows won’t open in my Mac’s browser — why?: That page is served by the app itself, so the setup screen (or Settings → Add Interaktiv Tap to your Traktor settings) must stay open while you use it — and the iPad and Mac must share a network: the same Wi-Fi, or the iPad’s Personal Hotspot. No shared network at all? Skip the page: AirDrop the exported file to the iPad and choose Interaktiv Tap, then AirDrop the merged file back.
Why does the connection keep dropping?: Use a reliable USB cable and keep the iPad awake while you play.
The iPad shows the wrong effect or hot cues after I connect — how do I fix it?: Tap SYNC in the header. It asks Traktor to send its current state, so the iPad’s read-outs — effect names, hot-cue colors, loop sizes — catch up to what’s loaded. Do this whenever you start a set or after reconnecting the iPad.
After an app update, PREV/NEXT, the FX buttons, or the meters act wrong — why?: The app and the mapping in Traktor must come from the same version. After every app update, run the round trip again: export your settings from Traktor with every box ticked, merge them in the app, and import the merged file back with every box ticked. That refreshes the mappings and the effect list in one step, and the read-outs settle after a tap on SYNC.
The surface paused and says the demo session ended — why?: That’s demo mode — the free way to play after the 7-day trial. Sessions pause after 15 minutes; Traktor keeps playing, only the surface takes a break. Relaunch the app to start a new session, or unlock once (Settings → Purchase) to remove the limit.
The audio is distorted or crackling — is the app causing it?: No — Interaktiv Tap carries no audio at all. It sends MIDI only; every sound comes from Traktor on the computer, and the iPad plays no part in sound quality. Distortion or crackling means the computer’s audio path is struggling: check Traktor’s Preferences → Audio Setup (the right audio device, and a larger latency if it crackles), keep channel and master levels out of the red, and watch the computer’s CPU load.

About

Who makes Interaktiv Tap

Interaktiv Tap is made by INTERAKTIV AUDIO LIMITED, a small studio based in Hong Kong, built by two people who perform with the tools they make: Andrey Koppel, a software architect, and Pierantonio Gualtieri, a producer and sound engineer.

Free trial & demo sessions

Interaktiv Tap is free to download and free to play in 15-minute demo sessions — the whole instrument. A session’s 15 minutes start once Traktor is connected and playing, so setting up never eats into it; when a session pauses, relaunch for another (Traktor keeps playing — only the surface takes a break). For uninterrupted days, start a 7-day free trial of everything — offered the first time you set up, and any time from Settings → Purchase. The trial runs once per Apple ID (the App Store keeps the record, so it survives reinstalls and new devices). One purchase removes the session limit for good.

Price, purchase, and availability

Version 1 Unlock is a one-time purchase — no subscription — that removes the demo-session limit and includes every update until version 2.0. The App Store shows each region its own price (you see it in the app too). One purchase covers all your own devices: sign in with the same Apple ID and tap Restore Purchase when you first set up, or any time in Settings → Purchase. Family Sharing covers your family group at no extra cost; the trial itself is per person. Bought Interaktiv Tap back when it was a paid download? You already own version 1 — the app unlocks automatically from your original App Store receipt (if it doesn’t show at once, relaunch while online). Refunds are handled by Apple through your App Store purchase history. Available on the App Store in 172 countries.

Privacy — what the app collects

Interaktiv Tap runs entirely on your iPad and collects nothing — no account, no sign-in, no analytics, no tracking. It never reads your audio, tracks, or recordings. The full privacy policy, covering website purchases and support, is at interaktivaudio.com/privacy.

Coming soon

Sample packs for Traktor Remix Decks are coming soon.
