The data read-only property of the MIDIMessageEvent interface returns the MIDI data bytes of a single MIDI message.
A Uint8Array.
In the following example midimessage events are listened for on all input ports. When a message is received the value of data is printed to the console.
inputs.forEach((input) => {
input.onmidimessage = (message) => {
console.log(message.data);
};
});
