Twenty tracks in. A set order out.
The sorter analyzes every track's tempo and key, then walks the Camelot wheel: gentle BPM climbs, harmonic neighbors, clashes flagged in red where you'll want a percussion-only blend.

Frequently asked questions
How does the sorter decide the order?
Greedy nearest-neighbor on two axes: from the slowest track it repeatedly picks the remaining track with the smallest tempo jump that's also harmonically compatible (same, ±1, or relative on the Camelot wheel). When nothing compatible is close in tempo, it takes the smallest clash and flags it red.
What do the red flags mean?
A transition where the keys genuinely fight. Your options at those seams: blend during percussion, use a hard cut or an echo-out, or transpose one track a semitone (the SongRemixer shifter does that). The flag is a heads-up, not a verdict.
Should sets always climb in BPM?
The default gentle climb suits most club sets, but great sets breathe — drop the energy on purpose sometimes. Treat the output as a strong first draft and drag the arc where your night needs it.
Can I trust the detected keys and tempos?
They're estimates — good ones, with confidence chips shown per track. Low-confidence rows deserve an ear check before you burn the order into a USB stick.
