How to mix it
In 2A at 138 BPM: 3A (B♭ minor) — move to 3A to push the floor harder; 2B (F♯ major) — switch to 2B for a mood change without losing the groove; 1A (A♭ minor) — drop to 1A to bring the room down gently.
Pitch range at ±6%: 130-146 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 9A rather than 2A; below -5% it reads as 7A. With key lock on, it stays 2A across the whole range.
