Web MIDI

In this repository I am experimenting with the JavaScript Web MIDI API to talk to various MIDI devices.

Running

npx serve . because CORS does not work with file://.

Akai APCmini Launchpad

I've implemented two hacks both having to do with the launchpad grid button lights. If you have this launchpad, you can connect it to your laptop and view this site in a Web MIDI supporting browser (Chrome, Edge).

Text Marquee

Fader Levels

Turn off the marquee animation first using the stop button.

Audio Visualizer

Turn off the marquee animation first using the stop button and then click the document body to initiate playback.

To-Do

Implement an OP-1 device and another for the keyboard

Figure out how to query the initial values of the faders

I captured the Ableton communication in my akai-apc-mini repository so maybe there will be a hint in that.

Model the launchpad in 3D and use my SVG 3D projector to render it

This will look cooler, prop it up so that it is slightly tilted back and to the right.

The SVG 3D projector repo of mine is called svg-3d.

Implement Snake or Etch-a-sketch or something silly like that

Implement a spectrum visualizer using the grid and Web Audio API

Add tests by mocking the devices
