# using npm
$ npm install --save midibus
# or using yarn
$ yarn add midibus// using ES6 modules
import * as midi from 'midibus'

</script>const midi = require('midibus')
// Assure that the browser have gained access to the MIDI interface
midi.access((err) => {
// Catch Error
if (err) throw err
// Show available inputs & outputs
console.log('Available inputs', midi.inputs)
console.log('Available outputs', midi.outputs)
// Create a new midi bus with available input & output
const magicBus = midi.bus(midi.inputs[0], midi.outputs[0])
// You can also omit the input or the output parameter
const myKeyBoard = midi.bus(midi.inputs[1], null)
// When a kb note is received, pipe it to magicBus, with a constant velocity
myKeyBoard.on('noteOn', ({channel, pitch}) => {
magicBus.send('noteOn', midi.msg(channel, pitch, 80))
})
