Please submit an issue in case of bugs or feature suggestions.

You can the examples locally or use the live version at https://haschdl.github.io/p5/launchController/Examples/LaunchController.html

1. Connect your Launch Control to your computer

2. Using a supported browser, navigate to demo page

3. If prompted, give permission to the web site to access MIDI devices

4. Example 1: This example shows the current value of knobs and status of pads. The library provides two ways of working with pads. In Toggle, each pad can be individually activated; in Radio, only one pad can be activated at a time. Radio is useful if you want to use the pads as selector - in example 2 I use it the pads to a pick a color from a list. See video in docs folder: LaunchControllerBrowser.mp4

5. Example 2: This example shows how to use the library in a p5.js drawing. Use knobs 1 to 4 to control the shape, and pick a color by using one of the pads.

Please note that using MIDI in the browser has very limited support. See https://caniuse.com/#search=MIDI page for details. Tested only with Chrome 70.
