How to mix it

In 4A at 87 BPM: 5A (C minor) — move to 5A to push the floor harder; 4B (A♭ major) — switch to 4B for a mood change without losing the groove; 3A (B♭ minor) — drop to 3A to bring the room down gently.

Pitch range at ±6%: 82-92 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 11A rather than 4A; below -5% it reads as 9A. With key lock on, it stays 4A across the whole range.

Programming: an opener or closing-set piece.
