How to mix it
In 8B at 126 BPM: 9B (G major) — move to 9B to push the floor harder; 8A (A minor) — switch to 8A for a mood change without losing the groove; 7B (F major) — drop to 7B to bring the room down gently.
Pitch range at ±6%: 118-134 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 3B rather than 8B; below -5% it reads as 1B. With key lock on, it stays 8B across the whole range.
Programming: a peak-time weapon — save it for the main stretch (energy 97/100).
