Find tracks by BPM or key

BPM and key in Storage

Open Storage (the file browser, not Your sound) and use the list view. Every analyzed audio file shows its tempo, key and Camelot code in one cell, for example 122 · Am · 8A. Hover it for the full reading.

Two column headers above the list sort on that data:

• BPM: sorts by tempo. Click again to flip the direction.
• Key: sorts into a mix order. The slowest track opens, and each next track is one that blends easily with the one before it, closest in tempo first. Click again to reverse the chain, a wind-down instead of a warm-up.

This works the same in your own folders and in shared folders you're a member of. Files without a detected BPM or key go to the bottom in both sorts, whichever direction you pick.

Storage has no BPM range or key filter. To narrow the list, open a folder or type part of a title in the search box.

On a narrow screen, such as a phone, the BPM and key column is hidden to give file names the room. The grid view shows the same reading on each card but has no sort headers. To sort, use the list view on a wider screen.

DJ harmonic mixing

The Camelot wheel encodes which keys mix together without clashing. Same number + different letter = relative major / minor. Adjacent numbers + same letter = perfect-fifth shift. Diagonal jumps usually clash.

Next to the key, the ↻ badge counts how many other tracks in the current view mix easily with this one. "Easily" means both of these hold:

• A compatible key: the same code, one step either way with the same letter, the other letter with the same number, or seven steps up with the same letter.
• A close tempo: within 6% of each other.

For 8A (A minor) the compatible keys are 8A, 7A (D minor), 9A (E minor), 8B (C major) and 3A (B flat minor).

A grey 0 means nothing in this view is an easy match. That is information, not a warning. The count only looks at the tracks you are looking at, so it changes when you open another folder.

When BPM / key are missing

If a track shows no value, it didn't pass the audio-analyzer's confidence threshold. See BPM and key detection for what the analysis does and when it deliberately answers nothing. Right after an upload the cell can also be empty while the analysis is still running; Storage fills it in when the result lands.

A track without a detected BPM or key has no reading and no ↻ badge, and sits at the bottom when you sort by BPM or Key. BPM and key are read-only, so when we can't tell, the field stays empty rather than carrying a guess.

DJ workflow tips

• Sort by BPM ascending → you've now got a tempo-walk you can DJ off the page (slow → fast or vice-versa, no clicking around).
• Versions don't show up as separate rows. The sort places a track once, on the BPM + key of its original upload (or of the version you last restored). Each version has its own BPM + key, so a newer version at a different tempo doesn't move the track.
