Free tool · setlist optimizer

Does your set
actually flow?

Paste your tracklist — key and BPM for each song — and see the smoothest order to play them in, plus exactly where the flow breaks.

Needs key + BPM per track already on hand (from Rekordbox, Serato, Mixed In Key, or your own notes). Try the example below first if you don't have a list handy.

Key must be a Camelot code, e.g. 8B or 5A. Example: Blinding Lights, 8B, 171. Up to 12 tracks.

How this works

Same key + tempo scoring as the Match Score tool, applied to every pair of neighboring tracks.

Σ

Pairwise scoring

Every consecutive pair in your set gets a match score. The set's overall score is the average of those transitions.

Reordering

The suggested order keeps your opening track fixed, then searches for a sequence that raises the average score — a fast heuristic, not an exhaustive search of every possible order.

Weakest link

The lowest-scoring transition in each order is flagged — that's the transition most likely to need a manual blend, transition effect, or skip.

Scoring is a general-purpose illustrative model, not a preview of Tuttii's actual in-app algorithm. Reordering uses a fast local-search heuristic, so very large or unusual sets may not find the true best order.
