How to mix it
In 5B at 116 BPM: 6B (B♭ major) — move to 6B to push the floor harder; 5A (C minor) — switch to 5A for a mood change without losing the groove; 4B (A♭ major) — drop to 4B to bring the room down gently.
Pitch range at ±6%: 109-123 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 12B rather than 5B; below -5% it reads as 10B. With key lock on, it stays 5B across the whole range.
Programming: a warm-up or breakdown cut — early set or after a peak to reset the room.
