How to mix it

In 11B at 100 BPM: 12B (E major) — move to 12B to push the floor harder; 11A (F♯ minor) — switch to 11A for a mood change without losing the groove; 10B (D major) — drop to 10B to bring the room down gently.

Pitch range at ±6%: 94-106 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 6B rather than 11B; below -5% it reads as 4B. With key lock on, it stays 11B across the whole range.

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