Drop a folder of MP3s. Hit Mix Now. Walk away. DropKit auto-mixes your tracks with beat-perfect transitions — no Rekordbox, no manual cueing.
DropKit detects real downbeats, phrase boundaries, and drops — then lines up incoming tracks so kicks land on kicks. No cue button required.
See lows, mids, and highs in separate lanes — like Rekordbox, only prettier. Spot energy drops and vocal entries at a glance.
No sudden cuts. CFX ramps low-to-high. Vocals never collide. Echo and reverb tails on every exit. The defaults your favorite DJs use.
Drop in an iCloud folder, an external drive, anything with MP3s. DropKit analyzes BPM, key (Camelot), structure, and energy — once.
Camelot wheel built in. Picks neighbor keys automatically so transitions sound musical, not random.
Thumbs up the mixes you love. DropKit builds a private style profile and gets better the more you use it.
Point DropKit at your MP3 library. It scans BPM, key, downbeats, and structure in the background.
DropKit picks the next track by key, energy, and phrase math — then beat-matches and aligns drops.
The queue auto-fills. Skip tracks you don't like, thumbs up the ones you do. The mix never stops.
DropKit v0 is a working prototype. It's unsigned (Apple Developer enrollment pending), so macOS will warn you on first open — that's normal for indie apps. Just follow the two-finger workaround below.
.dmg and drag DropKit into Applications.Why the warning? Apple charges $99/yr for developer signing, and our enrollment is currently stuck in ID verification. We'll re-sign and notarize the next build the moment Apple approves us — you won't have to do this again.
Open Terminal and paste:
xattr -dr com.apple.quarantine /Applications/DropKit.appThen double-click DropKit normally. This removes Apple's quarantine flag from the bundle.
Drop your email and we'll ping you when the Intel / Windows build lands.
During beta, yes. We may add a Pro tier later (cloud sync, more analyzer models, exports) but the core auto-mix will stay free for indie DJs.
No. DropKit reads your files and writes one tiny .analysis.json next to each MP3. Your audio files are never touched, renamed, or moved.
MP3, WAV, FLAC, M4A/AAC. If ffmpeg can read it, so can DropKit.
Yes. All analysis and mixing happens locally on your Mac. No upload, no streaming, no account required.
Not yet. We're macOS-first while the engine matures. Windows comes after v1, iPad is on the long-term roadmap.
Coming soon. v1 plays live through your speakers; an export-to-WAV button is on the list for the first paid update.
Not yet — v0 is unsigned because our Apple Developer enrollment is stuck in ID verification. On first open, macOS shows “DropKit Not Opened.” Click Done, then go to System Settings → Privacy & Security and click “Open Anyway” next to the DropKit notice. Once Apple approves us, we'll ship a signed + notarized build and the warning goes away forever.
v0 is Apple Silicon only (arm64). Intel build is on the list — drop your email in the form and we'll notify you the moment it's ready.
DropKit is a working prototype today. We're hiring a senior MIR engineer and a junior dev to take it from prototype to v1. The closed beta opens once the engine hits our internal quality bar. Want in early? Join the waitlist.
