Universal Key is a new way to characterize the tonality of a track no longer tied to the BPM it’s played at.

Instead of using a fixed key that changes when you pitch a song, it calculates the real harmonic identity of each track, whatever the tempo.

It’s like revealing the hidden logic behind music: suddenly, you can mix genres that never matched before.
The result feels almost unreal — as if every track was waiting to find its perfect twin.
