In 7B at 127 BPM: 8B (C major) — move to 8B to push the floor harder; 7A (D minor) — switch to 7A for a mood change without losing the groove; 6B (B♭ major) — drop to 6B to bring the room down gently.

Key on the fader: without key lock (Master Tempo on CDJs), above roughly +5% it plays a semitone higher, so treat it as 2B rather than 7B; below -5% it reads as 12B. With key lock on, it stays 7B across the whole range.
