Set prep
shouldn't outlast
the set

Three moves. Under a minute. A graded, export-ready set every single time.
01
// IMPORT

Load the crate

Rekordbox XML, Traktor NML or a Serato folder. BPM, key and genre arrive intact — zero re-analysis.

02
// DIAL IN

Set the vibe

Genre, length, energy archetype, BPM tolerance. Pin the anchor tracks, then commit.

03
// RUN

Generate + export

A graded set in seconds, planned to the minute. Inspect every transition, then push to Rekordbox, Traktor, Serato, PDF or TribeXR.

Specification

The theory,
running in
the dark

Every decision is graded against the rules DJs already mix by — and shown to you, never hidden.
01

Harmonic Matching

Every transition follows the Camelot wheel and is graded for key, tempo and energy — flawless blends across the set, with the reasoning on tap.

02

Energy Shaping

Five archetypes plus a planning canvas. Draw the curve of the night — warm-up, peak, close.

03

One-Click Import

Rekordbox, Traktor and Serato libraries land in seconds — crates and metadata fully intact.

04

Track Preview New

Hear any track without leaving the set you're building. Connect your music folder once and it plays your own files, full length. Chrome or Edge on desktop.

05

Smart Crates Pro

Dynamic crates auto-filter by genre, BPM, energy and key. Your library, self-organising.

06

Gigs + Crates

Schedule gigs, link the set you played, and build a gig crate in one click — your set plus its best-fit backups from your library.

07

Library Health

One score for your whole library, a ranked fix list, and one-click clean-up of messy genres and artist names. Clean data in, better sets out.

08

Slot Alternatives

Three ranked backups behind every slot. One tap swaps a track in, one tap swaps it back — a set you can flex on the night.

09

Planned to the Minute

A 90-minute request comes out 90 minutes long — planned against your real track lengths, not six-minute guesses.

★★★★★

SetFlow cut my prep time from two hours to two minutes. The harmonic matching is spot on — my transitions have never sounded better.

★★★★★

I was sceptical about auto-generated sets, but the energy curves actually understand how a set should flow. It feels like it was built by a DJ.

Questions

Before you
press play

What happens after the 7-day trial?

Your library and saved sets stay safe, but access is locked until you subscribe. Upgrade to Hobby or Pro to regain full access — or grab a one-time Weekend Pass for 72 hours of full Pro when you just need one gig covered.

Can I cancel any time?

Yes, cancel from Settings whenever you like. You keep full access until the end of your current billing period.

What if I don't use Rekordbox?

SetFlow fully supports Traktor and Serato too. Import your Traktor NML or point at your Serato folder — BPM, key, genre, and crate data all come with it. You can also add tracks manually in the Library.

Is my music data secure?

All data is stored securely in our database with strict user-scoped access. We never sell your data or share it for marketing. If you use the library fixes or set analysis, track metadata (title, artist, genre) is shared with our processing partners solely to compute the result — see the Privacy Policy for details.
