The correct MIDI note values for this chord are: [60, 64, 67, 70]. After you determine how many MIDI input or output devices are present in a system, you can inquire about the capabilities of each device. I made TypeScript compile to ES2017 so you can check the JavaScript code without any weird additions. We’ve only really scratched the surface of what’s possible with the WebMIDI API. The requestMIDIAccess() method returns a promise, so we need to establish success and failure callbacks. Defines an API supporting the MIDI protocol, enabling web applications to enumerate and select MIDI input and output devices on the client system and send and receive MIDI messages.

MIDI input requires an optically isolated input. The first value tells us what type of command was sent, the second is the note value, and the third is velocity. For all other browsers that don’t support it natively, Chris Wilson’s WebMIDIAPIShim library is a polyfill for the Web MIDI API, of which Chris is a co-author. After creating a reference for both the selected input and output device, I can attach a callback to the onmidimessage, which we will cover next. These messages contain information about the MIDI event such as pitch, velocity (how softly or loudly a note is played), timing, and more. This array typically contains three values (e.g. Often each MIDI channel (which shouldn't be confused with a channel of audio) is used to send the notes for a different instrument.

Here are the basics: Given this knowledge, we can expand our getMIDIMessage handler example above by intelligently parsing our MIDI messages coming from our inputs and passing them along to additional handler functions. MIDI messages relay musical and time-based information back and forth between devices. We can loop through our inputs and assign the listener like this: The MIDIMessageEvent object we get back contains a lot of information, but what we’re most interested in is the data array. Every time there's an incoming MIDI message from the selected input device, the handleMIDIMessage is executed. Get the latest release at GitHub or at npm..
