Fix wrong key detection in VirtualDJ.

No. Vibes has no VirtualDJ integration, so corrections to VirtualDJ's database are made in VirtualDJ's own Tag Editor, or by editing the file's key tag with the useKeyFromTag option turned on. Vibes works as a cross-check: analyze the same files in Vibes, compare its Camelot keys against VirtualDJ's values, and hand-verify only the tracks where the two detectors disagree. Correcting the tag and changing the audio are different jobs: if the track genuinely needs transposing rather than relabelling, the song key changer moves the pitch and leaves the tempo alone.

Because key detection is an estimation problem and each app uses a different algorithm. Sparse intros, detuned synths, heavy vocals, and key changes mid-track all push detectors toward different answers, usually a closely related key. Two apps agreeing is a good sign the value is right; disagreement is a prompt to check by ear.

In practice, yes. VirtualDJ calls it the Harmonic display, written with a leading zero (03A rather than 3A), and its own harmonic mixing guide explains it with the Camelot Wheel. Click the key value on the deck, or set the keyDisplay option, to switch between Harmonic and Musical (A#m). The mixing rule is identical: stay within the same number or one step away, and switch letters at the same number to move between minor and major.

VirtualDJ has two separate key changes. To correct the stored value, right-click the track in the browser, choose Tag Editor, and overwrite the Key field; VirtualDJ keeps it in its database, and Write Tag copies it into the file. To shift how a playing track sounds, use the deck's key adjustment arrows or the Key Match menu, which change the key in semitones and reset on the next load when resetKeyOnLoad is on. Fix the stored value first, since that is what every key-based sort and filter reads.
