Harmonic Mixing Set Planner
A good set is a journey: keys that agree, tempos that move gradually and energy that builds where you want it. The set planner checks all three for every transition, and it is free.

What the planner shows
- Transitions: key move and BPM change between every pair, with risky moves flagged
- Energy arc: a chart of the set, with jumps of more than two energy levels and big tempo changes highlighted
- Duplicates: a warning when you add a song that is already in the set, including other versions of it
- Auto mix: a recommended transition style, length and mix points for each pair
Lock tracks, then re-order
Lock your opener, closer or a peak-time track. Smart re-order arranges every unlocked track by key, BPM and energy around them, and dragging never moves a locked track.
Backups for every slot
Crowd not feeling it? Each slot can show 2–3 alternatives that fit the tracks before and after it. Swap one in with a click; the replaced track becomes a backup.
Shaping energy
A common shape is a warm-up around energy 4–5, a gradual build, one or two peaks and a short cool-down. Avoid jumping more than two levels between neighbours unless it is a deliberate moment, and use a slower blend or an in-between track to bridge it.

How to plan a harmonic DJ set
- Add tracks in order. Add from suggestions or search your library. Drag or use the arrows to reorder.
- Check every transition. Each pair shows its key move and tempo change, and the energy arc highlights jumps of more than two energy levels.
- Lock the anchors. Lock your opener, closer or any must-play track, then let Smart re-order arrange the rest around them by key, BPM and energy.
- Prepare backups and export. Open backups for any slot to see 2–3 compatible alternatives, then export to Rekordbox XML, M3U, CSV or a printable cheat sheet.
