EVALUA - a math synth VST
BotB Academy Bulletins
Level 10 Chipist
Another chip-related oddity from me.

EVALUA is a free experimental VST synth that uses math equations to create various waveforms. Much like those one-line C programs that produced generative music noises from a few years back, but geared towards conscious music production using any modern DAW. The plugin can create pitch-fixed textures, you can also use notes to make pitched sounds, making it a viable musical instrument.

It starts as simple as P&255 to get a saw wave, or P&128 to get a square wave, and can go really far with a mile long equations. Don't worry, you don't really have to understand all the underlying math in order to use the plugin. Just pick a preset and experiment with changing it a little bit, like the good old BASIC days.

https://www.osar.fr/protoplug/ might also be interesting. It's more like a prototyping environment, you get midi events and fill audio buffers, stuff like that.
