How to mix it
In 12A at 140 BPM: 1A (A♭ minor) — move to 1A to push the floor harder; 12B (E major) — switch to 12B for a mood change without losing the groove; 11A (F♯ minor) — drop to 11A to bring the room down gently.
Pitch range at ±6%: 132-148 BPM — anything in that window beatmatches without sounding stretched.
Key on the fader: without key lock (Master Tempo on CDJs), above roughly +5% it plays a semitone higher, so treat it as 7A rather than 12A; below -5% it reads as 5A. With key lock on, it stays 12A across the whole range.
Programming: a peak-time weapon — save it for the main stretch (energy 99/100).
