How to mix it

In 1A at 140 BPM: 2A (E♭ minor) — move to 2A to push the floor harder; 1B (B major) — switch to 1B for a mood change without losing the groove; 12A (D♭ minor) — drop to 12A 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 8A rather than 1A; below -5% it reads as 6A. With key lock on, it stays 1A across the whole range.

Programming: a peak-time weapon — save it for the main stretch (energy 99/100).
