KeyFinder 3.0 — key, tempo and DJ-prep analysis for macOS, as a desktop app and a VST3 / Audio Unit effect plug-in. Free, open source and fully local: your audio is only read, never modified and never uploaded.

What's new

  • New key model. KeyFinder now detects keys with its own small trained model instead of fixed templates. On fresh EDM test recordings it scores 57% exact keys, up from 41% for the previous detector.
  • New tempo detector. Reads bar-level rhythm rather than single beats, which fixes most half-time and 2/3 errors on hip-hop and trap. The other octave is always shown as a Half-time / Double-time alternative.
  • Redesigned app. One consistent layout across analysis, cues, mix planning and export, with seven themes.
  • Plug-in is now an audio effect. Put it on any audio track or the master. It listens continuously, and HOLD freezes the current read. (2.0 registered it as an instrument.)
  • DJ preparation. Cue suggestions you approve before export, a harmonic mix planner, and a persistent crate with manual key corrections.
  • MP3 fix. Some MP3s that previously failed to load now analyze correctly.

Install

  • App and plug-ins: open KeyFinder-v3.0.dmg, drag KeyFinder to Applications, and follow INSTALL.txt inside the disk image for the plug-ins.
  • Plug-ins only: unzip and copy KeyFinderVST.vst3 to ~/Library/Audio/Plug-Ins/VST3/ or KeyFinderVST.component to ~/Library/Audio/Plug-Ins/Components/, then rescan in your DAW.
  • KeyFinder is an independent release and is not notarized by Apple, so macOS asks you to confirm it the first time you open it. INSTALL.txt has the exact steps.

Requirements

macOS 12 or later, Intel and Apple Silicon (universal).

Limits

The tempo detector is built for 4/4 loop-based music (hip-hop, trap, EDM); expect more tempo errors on rock, jazz, swing and anything in 3/4. Measured results and their limits are in ACCURACY.md. KeyFinder makes no accuracy-parity claim against any commercial product.
