How to mix it
In 12B at 170 BPM: 1B (B major) — move to 1B to push the floor harder; 12A (D♭ minor) — switch to 12A for a mood change without losing the groove; 11B (A major) — drop to 11B to bring the room down gently.
Pitch range at ±6%: 160-180 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 7B rather than 12B; below -5% it reads as 5B. With key lock on, it stays 12B across the whole range.
