How to mix it

In 3A at 137 BPM: 4A (F minor) — move to 4A to push the floor harder; 3B (D♭ major) — switch to 3B for a mood change without losing the groove; 2A (E♭ minor) — drop to 2A to bring the room down gently.

Pitch range at ±6%: 129-145 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 10A rather than 3A; below -5% it reads as 8A. With key lock on, it stays 3A across the whole range.

Programming: a mid-set roller.
