Method
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.
Reference
Pitch Fader Ranges by Equipment
| Equipment | Pitch range |
|---|---|
| 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.

- How this page is made
- Tool pages are built from reusable page logic, internal DJ reference data, and visible on-page calculations. Programmatic reference pages are generated from structured data rather than hand-written one by one.
BPM, key, and genre labels can vary by edit, remaster, detection engine, and DJ software. Use these pages as a practical mixing reference, then verify important tracks in your own library.
