BMC, The Badass MIDI Controller!

BMC is an all-in-one Scalable MIDI Controller library with a companion Editor App specifically designed for the Arduino-Compatible Teensy development Boards. BMC allows you to build your own MIDI Controllers with a mixed number of Buttons/Leds/Encoders/Pots/Relays, etc with only a few lines of code!

You can use Web-Based Editor App with Google Chrome (all platforms except iOS) or on iOS with Web MIDI Browser from the App Store.

BMC can also be installed as a PWA (Progressive Web App) and run offline with Google Chrome only, just access the Web Editor and click the Install button at the bottom of the page, Chrome will then create a "shortcut" to the app which you can then open like a native app which will not need an internet connection to run. This will also work with Android tho a tablet is highly recommended for use as a phone may not display things properly.

The desktop app will no longer be available as it's much easier to keep the web app/PWA up to date so you'll always run the latest version!
