How to mix it

In 2B at 128 BPM: 3B (D♭ major) — move to 3B to push the floor harder; 2A (E♭ minor) — switch to 2A for a mood change without losing the groove; 1B (B major) — drop to 1B to bring the room down gently.

Pitch range at ±6%: 120-136 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 9B rather than 2B; below -5% it reads as 7B. With key lock on, it stays 2B across the whole range.

Programming: a peak-time weapon — save it for the main stretch (energy 85/100).
