How to mix it
In 10B at 138 BPM: 11B (A major) — move to 11B to push the floor harder; 10A (B minor) — switch to 10A for a mood change without losing the groove; 9B (G major) — drop to 9B to bring the room down gently.
Pitch range at ±6%: 130-146 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 5B rather than 10B; below -5% it reads as 3B. With key lock on, it stays 10B across the whole range.
Programming: a peak-time weapon — save it for the main stretch (energy 91/100).
