There is now a rudimentary demo of the JavaScript version of Radiant Voices:
https://sunvox.audio/
The drop-target at the top is to drag/drop SunVox projects. It'll play directly in SunVox JS but it will also load the project using Radiant Voices, to test out parts of the project-loading code.
The button at the bottom is the fun part though, even if the music is boring. It creates a new SunVox project using only JavaScript, loads it into the SunVox JS library, and optionally downloads the project to your computer.
The code snippet that does that is this:

There's a lot of work left to do, but reaching this milestone is very exciting. There's a lot of possibilities to unlock by manipulating SunVox files in a browser!
