How to mix it

In 5A at 123 BPM: 6A (G minor) — move to 6A to push the floor harder; 5B (E♭ major) — switch to 5B for a mood change without losing the groove; 4A (F minor) — drop to 4A to bring the room down gently.

Pitch range at ±6%: 116-130 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 12A rather than 5A; below -5% it reads as 10A. With key lock on, it stays 5A across the whole range.

Programming: a mid-set roller.
