It's alive, it's trapped inside, and it likes music.

Bzzzt! Glowies are powered by a tiny LiPo battery and rechargeable! Stay tuned for more incredibly fun designs coming to Maker Faire Bay Area! #mfba2025 #makerfaire

Curious what it takes to write 3D patterns for #Pixelblaze by @bhencke.bsky.social?
I've written up a tutorial: www.evilgeniuslabs.org/tutorials/pi...

Oooohh especially like xorcery!

It's fairly lightweight, but does have some overhead.

On an STM32G030 at 16MHz, it can do 2 voices with 4-5 nodes each with a sample rate of 12,500Hz. About 3K of flash.

So you have some number of voices/generators, could either be different "patches" or the same if you wanted polyphony. Then each voice has a number of audio nodes that can be envelopes, oscillators, filters, mixers, etc. Every node has an output and gain pointer input, and then specialized by type.
