How to mix it

In 8B at 71 BPM: 9B (G major) — move to 9B to push the floor harder; 8A (A minor) — switch to 8A for a mood change without losing the groove; 7B (F major) — drop to 7B to bring the room down gently.

Pitch range at ±6%: 67-75 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 3B rather than 8B; below -5% it reads as 1B. With key lock on, it stays 8B across the whole range.

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