Yesterday I had to plug in my keyboard to the computer and wasn't sure if it was working. How do I test? Well, I had to look up an older post, copy and paste some code to the console... what a drag.
I though it would be cool to have a page where you can test midi devices without touching any dirty filthy half-baked console code.
Hence https://www.onlinemusictools.com/webmiditest/ was born. A quick and dirty half-baked tool.
Here's a demonstration in a video:
The code is pretty simple. You find one input device and listen to its onmidimessage events. They you find one output device and call its send() method with an array of three values.
For more info see this previous post.
