Well, it was a long time ago when I first posted this demo - at the old forum. So here it is again - still the same geometry (Blender 2.7x?) and .babylon file. Very little change in the code - just replaced loading/controlling the audio. No longer using howler. js - now using the babylon.js call : new BABYLON.Sound …
And the version of babylon.js is now "Babylon.js v5.0.0-alpha.3 - WebGL2: loaded from “https://preview.babylonjs.com/babylon.js”. So just that one code change for the audio - the backwards compatibility that @Deltakosh has built into BJS is absolutely amazing and @JCPalmer 's fine Blender exporter has stood the test of time.
Tested in Windows 10 with Firefox and Chrome. Click the icon shown below in Chrome to get the music playing. The follow keys for controls:
1 : “o” key to turn music on/off
2.: “u” and “d” keys to turn music volume up/down
3 : “s” and “f” keys to move slower or faster
I hope everyone has a Merry Christmas in these terrible times . I know mine will be quieter than usual 
Stay Safe All, gryff
