Hey!
This seems like a good place to share an app I’m making. It’s based on the Web Audio API, and should work on Desktop/Mobile (Safari might not work yet, best to use chromium based browser or Firefox).
You can drag in Nodes from the bottom onto the canvas and they will trigger each other/play sounds. I think it’s self explanatory, but i also added a tutorial you can check.
The code is also hosted on github: https://github.com/roelkers/canvas-audio-chaos
I plan to add maybe a few more features/ add some effects, there is still some popping sounds, that i need to fix too but the project is still very young 
Any feedback and suggestions are welcome
