Key Shifting and Master Tempo

Pitch-shifting tracks for harmonic compatibility.

Key Shift turns 'almost compatible' into 'perfect'. One semitone, one new option.

+60 XP

// WHAT IT DOES

Key Shift pitches a track up or down by semitones without changing its tempo.

Lets you force harmonic compatibility — shift a 9A track down 1 to make it 8A and blend with your current 8A.

Available on CDJ-3000 and rekordbox Performance Mode.

Think of it like → A capo on a guitar. Same chord shapes, different actual pitch. The song now fits a different singer.
▸ WHY YOU CARE
  • • Doubles or triples your harmonic options per track.
  • • Rescues a track that would otherwise clash.
  • • Lets you transition between distant keys via small steps.

Glowing dot = your signal travelling through Live.
▸ LISTEN FOR
  • • Pitch artefacts beyond ±2 semitones
  • • Vocal unfamiliarity at extreme shifts
  • • tail artefacts
▸ WALKTHROUGH (5 steps)
  1. 1. DO: Current track at 8A; you want to play a 10A track next (incompatible).
    ▸ LISTEN: 10A vs 8A = full step apart on Camelot = clash.
  2. 2. DO: Shift the 10A track down 2 semitones → now 8A.
    ▸ LISTEN: Now harmonically compatible.
  3. 3. DO: Pre-listen in cue — verify no audible artefacts.
    ▸ LISTEN: ±2 should be clean.
  4. 4. DO: Mix in normally — blend works.
    ▸ LISTEN: Harmonic clash avoided.
  5. 5. DO: Practice plotting 'shift journeys' — distant key reachable via 2 shifts.
    ▸ LISTEN: Composition skill on top of selection.
▸ COMMON MISTAKES
  • ✗ Shifting beyond ±2 — sounds wrong.
  • ✗ Forgetting to reset Key Shift after — next play uses shifted version.
  • ✗ Shifting vocal-heavy tracks aggressively — unrecognisable.
