Control Traktor Pro 4 stem and remix decks from an iPad
Traktor Pro 4's stem and remix decks are built for hands-on performance — and a multi-touch iPad is a natural fit. With Interaktiv Tap you mix each stem and fire remix cells by touch, over USB, with the whole surface in front of you. Here's what that looks like.
What stem decks are
A stem file splits a track into four parts — typically drums, bass, melody, and vocals — that play in sync as a single deck. Traktor Pro 4's stem decks let you mix those four parts live: drop the vocal, filter the drums, push the bass under the next track. It's one of the most expressive things you can do in Traktor — and it asks for more than a couple of knobs.
Per-stem control on the iPad
On a stem deck, Interaktiv Tap gives every stem its own controls: a filter, an FX send, a volume fader, a mute, and a cue. Four stems, four channels, all under your fingers at once — so you can duck the vocal with one hand while filtering the drums with the other. That's the kind of parallel move a mouse or a single jog wheel can't make, and it's why a touch surface suits stems so well.
The feedback runs both ways, too: as you ride a stem fader, Traktor's meters and mute states light back up on the iPad, so you're never guessing where things sit.
In a set, that's the move where you let a track ride on just its drums and bass while you tease the incoming vocal in and out — then drop the full stem back as the phrase lands. With every part on its own fader and filter, you build and release that tension with your hands instead of clicking through one channel at a time.
The remix grid
Remix decks work differently — a grid of sample slots you trigger and layer. Interaktiv Tap lays out the slot launcher so you fire cells by touch, with punch-in and slot pages for deeper sets. Punch-in swaps a slot's sample on the next beat without stopping it; slot pages give you more banks than fit on screen at once, so a longer Remix set stays a tap away. Cells show what's playing, and one-shots and loops behave the way you set them up in Traktor. You build the Remix set on the computer; the iPad plays it — firing the cells, loops, and cues that are already there.
And because the FX pads track three axes and record, a filter-and-FX sweep across the stems can be captured and looped in time — so a build you played once keeps running while your hands move on to the next deck.
Why this is a Traktor Pro 4 thing
Stem and remix decks are core to Traktor Pro 4, and Interaktiv Tap plays the current Pro 4 — so the stem channels, the remix grid, and the two-way feedback line up with what's actually on screen. Most iPad control apps target older Traktor versions or stay deck-agnostic; this one maps the current Pro 4 surface. See exactly which Traktor functions it maps.
How it connects
It all runs over a single USB cable: plug the iPad into the computer running Traktor Pro 4, import the mapping, set the iPad as MIDI in and out, and play. New to this? Here's how playing Traktor from an iPad works — or see how the iPad Traktor controller options compare.
