The presentation is at https://ad8e.pages.dev/keyboard. This repository is for patches, issues, discussions, questions, etc.

keyboard.html can run locally. The downside is that the timbre is a sine wave with 10-20 ms latency, because your browser isn't nice about locally downloaded files. To avoid this latency, just visit the original webpage.

If you want to both avoid latency and run the keyboard locally:

1. Download the repository
2. Open a console. If you're on Linux, run ./corsplease.py. If you're on Windows, run python3 corsplease.py. This sets up a local web server to handle CORS, which makes your browser happy.
3. Visit http://127.0.0.1:8000/keyboard.html in your web browser.

See this page for security considerations of running a local web server. Only your own computer can connect to this server; other computers on your network cannot. So if you're not running untrusted programs, it should be safe.
