How to mix it

In 6B at 128 BPM: 7B (F major) — move to 7B to push the floor harder; 6A (G minor) — switch to 6A for a mood change without losing the groove; 5B (E♭ major) — drop to 5B 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 1B rather than 6B; below -5% it reads as 11B. With key lock on, it stays 6B across the whole range.

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