At 170 BPM in B♭ minor (3A), Morse Code is a very fast drum n bass production. Tonally it lands dark and driving. The mix is almost entirely instrumental. The master is loud and heavily compressed. The master keeps unusual dynamic range for club music (crest 16 dB). A 1997 production that still circulates in sets. More underground than 99% of Roni Size's catalogue. For programming, treat it as a high-intensity peak cut.

Mixes harmonically
3A → 2A · 4A · 3BFrom 3A, 4A (F minor) lifts the energy a step; 3B (D♭ major) brightens to the relative major; 2A (E♭ minor) cools the energy down a step.
How to mix it
In 3A at 170 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%: 160-180 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 high-intensity peak cut.
