How to mix it
In 11A at 134 BPM: 12A (D♭ minor) — move to 12A to push the floor harder; 11B (A major) — switch to 11B for a mood change without losing the groove; 10A (B minor) — drop to 10A to bring the room down gently.
Pitch range at ±6%: 126-142 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 6A rather than 11A; below -5% it reads as 4A. With key lock on, it stays 11A across the whole range.
