How to mix it
In 6B at 173 BPM: 7B (F major) — move to 7B to push the floor harder; 6A (G minor) — switch to 6A for a mood change without losing the groove; 5B (E♭ major) — drop to 5B to bring the room down gently.
Pitch range at ±6%: 163-183 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 1B rather than 6B; below -5% it reads as 11B. With key lock on, it stays 6B across the whole range.
Programming: a warm-up or breakdown cut — early set or after a peak to reset the room.
