How to mix it

In 10A at 125 BPM: 11A (F♯ minor) — move to 11A to push the floor harder; 10B (D major) — switch to 10B for a mood change without losing the groove; 9A (E minor) — drop to 9A to bring the room down gently.

Pitch range at ±6%: 117-133 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 5A rather than 10A; below -5% it reads as 3A. With key lock on, it stays 10A across the whole range.

Programming: a warm-up or breakdown cut — early set or after a peak to reset the room.
