Features

Everything Alpha does, in the order you'd actually use it: get your music in, build the set, write the drive.

01

Get your music in

Pick your tracks

Point Alpha at a whole folder, at several, or at individual tracks from different places. They all land in one list.

  • Whole folders and hand-picked files, mixed freely
  • Everything collects in one list before anything runs
  • Nothing is copied or moved — your files stay where they are

Analysis

Alpha reads tempo, key, energy and loudness straight out of the audio, on your own machine.

  • BPM, musical key in Camelot notation, energy and loudness
  • Runs locally — no internet connection needed for it
  • Read-only: your audio files are never modified

rekordbox import

Coming from Pioneer? Export your collection as a rekordbox XML and Alpha keeps the BPM, key and beatgrid rekordbox already worked out.

  • No re-analysis of tempo, key or beatgrid
  • Pick tracks for one set, or write the whole library to the stick as-is
  • Filter the import by search, key, genre or BPM range
  • Cue points are not carried over from the XML
02

Build the set

Compose

Draw the energy arc your night should follow, say how long it runs, and Alpha orders the tracks to match.

  • Five arc templates — Journey, Wave, Build, Peak-time, Cooldown — or drag the curve yourself
  • Set the target length in 10-minute steps
  • Two sliders: harmonic transitions vs. following your curve, and key vs. tempo matching

Refine

Audition every track, drag the bars to reorder them, and drop anything that doesn't fit.

  • Built-in mini-player for pre-listening
  • Drag a bar to move a track to a new position
  • Removing a track takes it out of this set — never off your disk
03

Write the drive

Denon Engine OS export

Writes a proper Engine OS drive: your tracks, their metadata and the playlist order, ready to play the moment you plug in.

  • Engine OS 3.x, the format the whole Engine DJ family reads
  • Validates the result, then lets you eject safely
  • Adds to the existing library — it never erases the stick

rekordbox export

Writes a Pioneer DJ / AlphaTheta USB that a CDJ or XDJ reads directly — with no rekordbox software anywhere in the chain.

  • Plugs straight into the player — rekordbox doesn't need to be installed
  • Writes both libraries: the classic one and the newer encrypted one the latest players prefer
  • Beat grid, waveform, cues and artwork written as the analysis files the player reads
  • CDJ-3000 and 2000NXS2, XDJ-RX3 and RX2, XZ, 1000MK2, 700, OPUS-QUAD, XDJ-AZ
  • One constant beat grid per track — tempo changes inside a track aren't modelled
  • A new target — worth confirming on your own player

Match loudness

Every track in the set plays at the same perceived loudness, so you're not riding the gain between songs.

  • Set a target in LUFS, from −20 to −6
  • Reference points for Apple Music, streaming, club and DJ master
  • Peaks never pass −1 dB, so nothing clips
  • Applied to the copies on the stick — your library files stay untouched

Skip duplicates

A track that's already on the stick is linked, not copied a second time — however many playlists use it.

  • One file on the drive, linked from every playlist that needs it
  • Saves space and cuts the write time
  • The full playlist order is always written — only the copy is skipped

Backup before every write

Before Alpha touches a stick, it copies that stick's Engine library to your own computer.

  • Kept on your machine, not on the stick — so it survives a wipe
  • Restore an earlier version whenever you need it
  • Happens automatically on every write
04

Manage your sticks

Playlists on device

Plug a drive in and Alpha shows what's already on it — so you can tidy up without opening Engine DJ.

  • See every playlist on the connected stick
  • Rename or delete them
  • Roll the library back to an earlier backup

Also: DJ software on a laptop

Alpha is built for sticks that go straight into the gear. If you play from a laptop instead, it writes those libraries too — in the app they sit behind + Also export for DJ software (laptop) in the target picker. None of these produce a standalone stick: a computer running the software reads the drive.

VirtualDJ export

Writes a VirtualDJ library onto the drive: every track's tags, BPM and key, plus the playlist in the order you built it.

  • Audio, artist, title, album, year, BPM, key and length
  • Your key is converted to Open Key, the notation VirtualDJ uses — Camelot 8A is written 1m
  • The set arrives as a ready-made playlist, not a loose pile of files

Serato export

Writes a portable Serato crate onto the drive, with the beat grid baked into the copied files' own Serato tags.

  • The crate shows up in your library the moment you plug the drive into the laptop
  • Beat grid plus title, artist, album, BPM and key written into every copied file
  • Serato only scans a drive's root — Alpha warns you if you pick a subfolder
  • Hot cues and loops aren't written yet

Traktor export

Writes a collection.nml — Traktor's own library format — alongside the audio, ready to pull into Traktor Pro.

  • Every track with its tempo, key and beat grid, plus the playlist in set order
  • Any destination folder works — Traktor isn't fussy about where it sits
  • Traktor doesn't scan drives — you import it once via File → Import Collection
  • One constant beat grid per track — tempo changes inside a track aren't modelled

Try it on your own music

Every feature on this page is in the free download. The limits: it stops after 10 tracks and runs on one device — still enough for one real set on your own stick, which is the only way to judge a DJ tool anyway.
