How to mix it

In 4B at 122 BPM: 5B (E♭ major) — move to 5B to push the floor harder; 4A (F minor) — switch to 4A for a mood change without losing the groove; 3B (D♭ major) — drop to 3B to bring the room down gently.

Pitch range at ±6%: 115-129 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 11B rather than 4B; below -5% it reads as 9B. With key lock on, it stays 4B across the whole range.

Programming: a mid-set roller.
