AI DJ Studio: Stems & Mixer

Split any song into layers

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Bring any song, get vocal, drums, bass and melody on their own faders. Mark the drop once, hit it all night. Split any song into layers, then mix with them. Bring a track from Files and AI DJ Studio separates it into vocal, drums, bass and melody, each on its own pad. Tap one to drop it out. Hold it to hear it alone. Both decks run under a single playhead, so the beat grid, the loops and the scratch move the whole song, not a fragment. MARK IT AT HOME, HIT IT IN THE SET The cue point of a club deck needs a headphone feed a phone does not have. So you prepare instead: listen at home, drop a mark where the drop is, name it in your own words. In a set the mark is a button. Press it and the track starts exactly there, snapped to the beat, with no fade to knock it out of time. MIX WITH ONE SPEAKER Line up the beat markers on the two waveforms, or press SYNC. The MIX button takes the whole transition on its own: it matches tempo, enters at your mark, and crossfades over eight bars. A MASHUP IN ONE PRESS The vocal of one deck over the instrumental of the other. Six faders move at once, on tracks written to fit each other: every factory pair shares a tempo and a compatible key. PRESS YOUR OWN RECORDS Describe a track and it arrives whole, one to three minutes, at the tempo and key you asked for, with cover art on the label and already split into layers. ALSO INSIDE Three band EQ with true kill, a bipolar filter, seven momentary effects locked to the beat, loops from one to sixteen bars, a nine pad kit of sampled percussion, and a landscape console with two full size platters. Curated tracks open by watching a short video. Credits pay for AI generation. Premium removes ads and separates as much as you want. Premium is an auto-renewable monthly subscription.

The crate is new, and so is the way you play it. TWELVE TRACKS, SIX PAIRS Every pair shares a tempo and sits in neighbouring keys, one instrumental and one with vocals, so any vocal over any instrumental just works. House, tech house, afrobeats, hip hop, trap and drum and bass. ONE TAP TO MIX The new transition button does the whole thing: matches the tempo, takes the incoming track to its drop, starts it and crosses the fader over eight bars. Play for ten minutes before you know how to do it by hand. HEAR BEFORE YOU LOAD Tap play on any track in the crate to audition it, right at the drop, without touching what is on the decks. VOCAL OR INSTRUMENTAL, AT A GLANCE Every track says which it is, because you never want two vocals at once. NEW PADS Nine performance one shots rebuilt from real public domain recordings, and tuned to be audible on a phone speaker. Also fixed: pressing play after a track ended did nothing.
