How to mix it
In 8A at 130 BPM: 9A (E minor) — move to 9A to push the floor harder; 8B (C major) — switch to 8B for a mood change without losing the groove; 7A (D minor) — drop to 7A to bring the room down gently.
Pitch range at ±6%: 122-138 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 3A rather than 8A; below -5% it reads as 1A. With key lock on, it stays 8A across the whole range.
