Tidal Song Mapper

Drop a track. The mapper finds its BPM and its key (and says how sure it is — several key profiles vote, and you can overrule them by ear), draws the waveform, and lets you annotate the structure on it: intro, verse, pre-chorus, chorus, drop, bridge, break, outro, as blocks you move and resize.

From that it writes a .tidal song map: the tempo as setcps, the scale, one section after another, and deliberately simple patterns to start from — copy a section into your Tidal editor, run it, and bend the values until it sounds like the track. Everything happens in the browser; no file leaves your machine.
