I know it's far from the scope of the purpose of being a plain visualizer/game, but I would love to suggest - and I guess I could try to learn how to do it myself I suppose, but I don't know rust just yet :^) - what about adding a plugin system/interface to an online repository of MIDI files to this?

Would be awesome to have a centralized frictionless way to share/grab midi files. And thank you for all your hard work!

I'm thinking it would be awesome to have a general-purpose plugin system - eg if someone else wrote a 'tutor' plugin, or 'multi-user' plugin, etc. Plus, I'm just spitballing here, but it might be possible to write it so that any language that compiles down to .wasm would be allowed, right? Huge flexibility there. OOooh and maybe a package manager too, while I'm just listing pie-in-the-sky desired features, lol

As long as there is a nice rest API for midi archive I would be open to add an in-app midi browser, but I don't want to maintain and pay for hosting of such an archive myself.

This is planned for Parture if you like to help out (Rust+Elm+SkyNet/IPFS): https://parture.org

amazing!!!!!!! thank you for the link
