How to mix it
In 2B at 143 BPM: 3B (D♭ major) — move to 3B to push the floor harder; 2A (E♭ minor) — switch to 2A for a mood change without losing the groove; 1B (B major) — drop to 1B to bring the room down gently.
Pitch range at ±6%: 134-152 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 9B rather than 2B; below -5% it reads as 7B. With key lock on, it stays 2B across the whole range.
Programming: a warm-up or breakdown cut — early set or after a peak to reset the room.
