From discovery to the decks — one flow
Colour waveforms that read like a map
Bass, mids and highs each get their own colour, so a track’s whole story — the intro, the build, the drop, the breakdown — is visible before you ever press play. Flip to STEM view and watch the vocal, drums and bassline split into separate layers.
- Three-band frequency colouring
- Stem view — isolate vocals, drums & bass
- HD zoom right down to the beat
Auto-cues that land on the moments that matter
Smart Analysis reads each track’s phrasing — the 8, 16 and 32-bar blocks a DJ actually mixes around — and drops cue points at the mix-in, the drop and the switch-up automatically. The beat grid is one keystroke to check and two to fix, so even live recordings grid up fast.
- Phrase-aware auto cue points, 8 pads filled
- One-key beat-grid adjust — tap the downbeat, done
- Cue roles & colours that follow you to the booth
BPM and key you can bet a set on
Multiple detectors analyse every track and cross-check each other, so the tempo and key on the label are the tempo and key in the speakers. Hover any value and it tells you exactly where it came from — no more half-time surprises three tracks deep.
- Cross-validated BPM & key detection
- Energy scoring for reading the room
- Every value shows its source on hover
Metadata that fixes itself
Mastermind enriches every track from the sources that matter — genre, label, release year and full-size album art pulled in automatically. Messy filenames get verified and cleaned to a consistent shape, duplicates get flagged with the best copy recommended, and every change is reversible.
- Auto-enriched genre, label & album art
- Filename verify & clean — evidence-backed, reversible
- Duplicate finder with a recommended keep
Filter like you think, crate in seconds
Search by anything — BPM range, key, energy, genre, label — and the table narrows live as you type. Save any filter as a Smart Crate and it keeps filling itself as your library grows: “peak-time techno, 128–132, high energy” is a crate that’s never out of date.
- Instant search across your whole library
- Smart Crates that fill themselves by rule
- Playlists built in seconds, not evenings
Customise everything you look at
Paint your waveforms your own colours in the Palette Studio — band by band, with live preview. Every track table is fully resizable: drag columns, pick which ones show, set row heights, and each page remembers its own layout. Set it up once and the whole app looks the way you think.
- Custom waveform colours — full Palette Studio
- Resizable track table with saved layouts per page
- Key notation, tempo range & defaults that stick
An Artist Hub for everyone you play
Every artist in your crate gets a page — your history with them, their full discography, and a mix-compatibility read against your whole library. One glance tells you whether their sound slots into your sets or stretches them.
- Photo, bio, releases & your play history
- Mix-compatibility scored against your library
- Links out to Beatport, Discogs & Spotify
Get more out of your tracks
Every track splits into its stems — vocals, drums, bass and instruments — right on your machine. Solo the vocal to learn a hook, kill the drums to hear the musicality, or export any stem as its own audio file: grab an acapella in one click and take it to the studio.
- On-device stem separation — no upload
- Solo or mute vocals, drums, bass & more
- Stem exporter — acapellas & instrumentals as files
Harmonic mixing, the way you read it
Camelot, classical, or both side-by-side — pick once and every key in the app follows. Compatible keys glow against whatever’s playing, so the harmonic blend is always the obvious next move.
- Camelot / classical / both — your call
- Key-match glow against the playing track
- Energy-step suggestions for the next tune
Export straight to your gear
Your cues, grids, colours and playlists travel with you — rekordbox XML, Serato tag write-back, Traktor NML, or a USB stick your CDJs read natively. Prep once in Mastermind and it shows up in the booth exactly how you left it.
- rekordbox, Serato & Traktor hand-offs
- Direct USB / CDJ export
- Cues, grids & loved status carry over
