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!

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.

Selecting different materials would not change much. Call the frequencies \lambda_1, \lambda_2, \lambda_3...

You can prove that changing the material has no effect on the relative frequencies: \lambda_2 / \lambda_1, \lambda_3 / \lambda_1, etc. are completely independent of the material.

The shape is the determining factor; changing the materials (and hence the wave speed) just dilates the whole spectrum.
