Dynamic music player almost done

Hi everyone, I recorded a (maybe longer than it should) video showing the management of music tracks in real time for the audio tool I'm developing for RPGs.

The music manager supports up to 10 tracks per music (games rarely uses more than 4) and these tracks can be toggled using numeric keys (0 to 9).

As the ambient and sfxs managers are finished, the tool is almost ready to be released. It will be free and run on browser and desktop (Windows) at release.

Not much is shown but any feedback is appreciated
