Musical performance animation, inspired by Animusic (youtu.be)

I felt inspired by animusic animations and decided to try to do it myself.

I made the song only using the default plugins from LMMS. I transformed it to MIDI using this converter.

I then converted MIDI to a JSON that contains only what I need using a program in my Github repo (see below). And I import this generated JSON into blender animations using an extension (same Github repo).

Once I have the animations, I used drivers to get the animated values inside geometry nodes to launch and simulate the balls, vibrate the xylophone/marimba, oscillate bass strings and scale trumpets. The hi-hat, snare, drumstick and trombone were animated through drivers in properties GUI.

Rendered with cycles, all materials are the default material, I just changed color, metallic and roughness values, as I decided I didn't want to spend more time into this.

The video appears to be broken.

True, thanks for letting me know, it won't work on my phone. Switched to YouTube url.

Neat.

The original did have a locally-ran demo (ATI pipe dreams), that's better because it's lower data and adds up with multiple songs/stages. Makes even more sense now with portable software, and better-yet web exports.

BGE seems like it may have been a fine option for exporting a live-rendered animation at one time, but I'm not sure if it is currently. Though I guess frameworks like Raylib, Ogre, libGDX etc could even work (or Godot).

It also could probably be branched off into a benchmark or maybe even a rhythm game.

Oh, I didn't know they released a demo like that. My first idea was to make a program to play it using a game engine (bevy), but I switched to blender because I didn't need it to be real time.
