Very cool. Number keys and QWERTYU (or clicking the rows on the right) trigger the "modes" in isolation, which are surprisingly microtonal. Also you can draw your own drums! What! That's so cool

I love it. I wish I could select materials.

Thanks for reposting this! I'm the developer (BaselAshraf81) - happy to answer questions or hear suggestions here. If you find it interesting, a star on the GitHub repo helps a lot. And don't forget to follow me on github, I build cool stuff!

I'm not sure if I'm learning a lot. All of the shapes and click locations basically sound the same to me.

Try `1 + 0.16 cos(4 t) + 0.08 cos(12 t + pi/6) + 0.04 cos(36 t + pi/3) + 0.02 cos(108 t + pi/2)`

Very cool, reminds me of some of Aphex Twin’s percussive elements
