How to mix it
In 1B at 135 BPM: 2B (F♯ major) — move to 2B to push the floor harder; 1A (A♭ minor) — switch to 1A for a mood change without losing the groove; 12B (E major) — drop to 12B to bring the room down gently.
Pitch range at ±6%: 127-143 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 8B rather than 1B; below -5% it reads as 6B. With key lock on, it stays 1B across the whole range.
Programming: a peak-time weapon — save it for the main stretch (energy 98/100).
