How to mix it
In 3B at 175 BPM: 4B (A♭ major) — move to 4B to push the floor harder; 3A (B♭ minor) — switch to 3A for a mood change without losing the groove; 2B (F♯ major) — drop to 2B to bring the room down gently.
Pitch range at ±6%: 164-186 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 10B rather than 3B; below -5% it reads as 8B. With key lock on, it stays 3B across the whole range.
Programming: an opener or closing-set piece.
