Stop trusting whatever the tags happen to say. DJ Toolbox Pro's key and BPM analyzer reads every file in your library and returns the exact tempo, musical key and Camelot code — the numbers you actually need to mix harmonically — batch-processed in the background while you make coffee.
Mix Architect
Point it at your whole collection and it reads every track — exact BPM, musical key and Camelot code — so everything comes back tagged, sortable and ready to mix harmonically.

Song key finder & BPM counter in one
Tags lie. This song key finder and BPM counter reads every file in your collection and returns the exact tempo, the true musical key, and the Camelot code — the three numbers you actually need to beatmatch and mix in key. Automatic key detection and BPM detection, no tapping tempo by hand. Batch your whole library in the background and come back to a crate that's finally accurate.
Analyze once, stay analyzed
Point it at your existing Rekordbox, Serato or Traktor library and it works through the lot, then remembers the results so you never re-analyze the same track twice. Everything comes back sortable by key and BPM, so compatible tracks line up at a glance and harmonic mixing stops being guesswork.
More than a batch analyzer
- Instant Track Inspector — drag any single song in and this key finder returns its key, BPM and Camelot number on the spot, perfect for a quick check before you load it.
- Set Advisor — feed it an ordered set and it grades the flow, maps the energy curve, and suggests reorders that keep every transition in key.
- Camelot-ready — every track is labelled for the Camelot wheel, so harmonic mixing and beatmatching to a neighbouring key is as easy as reading a number.
Runs offline, on your machine
A 10,000-track collection gets analyzed once and stays that way — no cloud, no uploads, no waiting on a server. Your library never leaves your Mac.
