Pitch & Tempo Calculator
Calculate how pitch fader adjustments affect BPM, or find the exact pitch % needed to match two tempos. Works with any DJ setup -CDJs, turntables, or software.
How Pitch Faders Work
The pitch fader on a CDJ, turntable, or DJ controller changes the playback speed of a track by a percentage. Moving the fader to +4% speeds the track up by 4%, increasing both the tempo and (without key lock) the pitch. This is the fundamental mechanism behind manual beatmatching.
The formula is straightforward: new BPM = original BPM × (1 + pitch% / 100). A 128 BPM track at +6% plays at 135.68 BPM. Going the other direction, to find the pitch adjustment needed: pitch% = ((target / original) - 1) × 100.
Pitch Fader Ranges by Equipment
- Pioneer CDJ-3000: ±6%, ±10%, ±16%, Wide (±100%)
- Pioneer CDJ-2000NXS2: ±6%, ±10%, ±16%, Wide
- Technics SL-1200: ±8% (standard), ±16% with modifications
- Traktor / Serato / Rekordbox: Software-configurable, typically ±8% to ±100%
Pitch, Tempo, and Key
Without key lock (Master Tempo), changing the pitch fader affects both tempo and musical key. Every ~6% change shifts the key by approximately one semitone. This means a +6% speed boost on a track in C major would play it roughly in C♯ major. Modern CDJs and DJ software offer Master Tempo / Key Lock to decouple tempo from pitch, keeping the key stable even when the speed changes. Use our Key Transposer to see exactly how pitch shifts affect key.
