In 9A at 127 BPM: 10A (B minor) — move to 10A to push the floor harder; 9B (G major) — switch to 9B for a mood change without losing the groove; 8A (A minor) — drop to 8A to bring the room down gently.
Pitch range at ±6%: 119-135 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 4A rather than 9A; below -5% it reads as 2A. With key lock on, it stays 9A across the whole range.
Programming: a peak-time weapon — save it for the main stretch (energy 88/100).
