hypermidi

Load and play MIDI from Hyperdrive over the DAT network using timidity and hyperdrive.

Installation

$ npm install hypermidi

Usage

const midi = require('hypermidi')('/path/to/storage', 'KEY', opts)
// replicate somehow (discovery-swarm-web works well)
midi.play('/path/to/track.mid') // probably need a user gesture/event

The module expects to load libtimidity.wasm and freepats sounds sets over the network so your web server should be able to serve them.

Example

const hypermidi = require('hyperidi')
const Discovery = require('discovery-swarm-web')
const ram = require('random-access-memory')

const key = '4f25776241c2333fa2cb724aac6fcf4d49f6fa7e243238c589cf021728762695'
const midi = hypermidi(ram, key)

global.midi = midi
midi.ready(() => {
  const swarm = new Discovery({
    stream: () => midi.replicate()
  })

  swarm.join(midi.discoveryKey)

  const button = document.body.appendChild(document.createElement('button'))
  button.innerText = 'play'
  button.onclick = () => midi.play('Bean.mid', console.log)
})

Run with budo

$ budo example.js --live --port 3000 --dir node_modules/timidity --dir node_modules/freepats

Visit http://localhost:3000 and press play! Assuming you can connect to the DAT network and replicate the archive.
