       <h3>Design the whole set</h3>
       Drop tracks in and <b>✨ Harmonize</b> orders them by Camelot key, tempo and energy arc, using simulated annealing over the whole set. Mix-in and mix-out points come from the analysed structure, and transition lengths fit the intro and outro of each pair.

-      Slide tracks and transitions by bars, collapse lanes, solo or mute them, shape a lane with its EQ and filter, and render the result to WAV with a cue sheet, faster than real time. Everything else lives in a DJ.Studio-style bar at the bottom: the transport, plus tabs for Zoom, Playlist (a sortable track table with keys, harmonic matches, energy and BPM), Transition, Track, Mashups and Master. Two <b>sample lanes</b> take one-shots, loops and FX dropped from Finder. Drag across a track's waveform to select a range and right-click to copy it to a sample lane: the full sound, or just its drums, bass, melody, vocals, instrumental or drums + bass (⌘L, ⇧⌘1–6). The copy is stretched and key-shifted like the mix plays it, or you can save it as a WAV. Every edit can be undone.
