Heat: drum n bass, D♭ major (3B), 175 BPM. Tonally it lands punchy, neutral in mood. The mix is almost entirely instrumental. Its spectrum is weighted to the sub and kick, with a heavy low end. The master keeps unusual dynamic range for club music (crest 16 dB). Better known than 99% of Calibre's catalogue. For programming, treat it as a floor-filler.

How to mix it

In 3B at 175 BPM: 4B (A♭ major) — move to 4B to push the floor harder; 3A (B♭ minor) — switch to 3A for a mood change without losing the groove; 2B (F♯ major) — drop to 2B to bring the room down gently.

Pitch range at ±6%: 164-186 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 10B rather than 3B; below -5% it reads as 8B. With key lock on, it stays 3B across the whole range.

Programming: a floor-filler.
