## Tutorial
Open Node.js command line window.
Create React application from [https://reactjs.org/tutorial/tutorial.html](https://reactjs.org/tutorial/tutorial.html)
Modify package.json to add dependency to **midi-sounds-react** component
```
{
"name": "my-test",
"version": "0.1.0",
"private": true,
"homepage": "https://myserver",
"dependencies": {
"react": "^16.2.0",
"react-dom": "^16.2.0",
"react-scripts": "1.1.0",
"midi-sounds-react": "^1.2.45"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
}
}
```
Install dependencies
```
npm install
```
Start application
```
npm start
```
Navigate browser to http://localhost:3000
Modify src/App.js to add an Component and button.
```js
import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
import MIDISounds from 'midi-sounds-react';
class App extends Component {
playTestInstrument() {
this.midiSounds.playChordNow(3, [60], 2.5);
}
render() {
return (
Welcome to midi-sounds-react example 1
Press Play to play instrument sound.
Play
(this.midiSounds = ref)} appElementName="root" instruments={[3]} />
);
}
}
export default App;
```
### Main parts
```js
import MIDISounds from 'midi-sounds-react';
```
- import **midi-sounds-react** component
```html
(this.midiSounds = ref)}
appElementName="root" instruments={[3]}
/>
```
- insert component into page
```js
this.midiSounds.playChordNow(3, [60], 2.5);
```
- play sound
See [live example](https://surikov.github.io/midi-sounds-react-examples/examples/midi-sounds-example1/build), download example from [https://github.com/surikov/midi-sounds-react-examples](https://github.com/surikov/midi-sounds-react-examples).
## Reference
### Component parameters
```html
(this.midiSounds = ref)}
appElementName="root"
instruments={[111]}
drums={[2,33]}
/>
```
- this.midiSounds - variable to use component from code
- appElementName - name of main div of application
- instruments - array of instruments to preload
- drums - array of drums to preload
### Initializing
MIDISounds will be initialized after first render. Use componentDidMount to rerender page with initialized component.
```js
componentDidMount() {
console.log('rerender after init');
this.setState(this.state);
}
```
[Live example](https://surikov.github.io/midi-sounds-react-examples/examples/midi-sounds-example4/build)
### Play continuous note sounds
Use this.midiSounds.player.queueWaveTable to start sound and return reference to envelope.
Use envelope.cancel() to stop sound.
[Live example](https://surikov.github.io/midi-sounds-react-examples/examples/midi-sounds-example10/build)
### List of drums
Use this.midiSounds.player.loader.drumsKeys() to get array of drums.
Use this.midiSounds.player.loader.drumInfo(i).title to get readable drum name.
[Live example](https://surikov.github.io/midi-sounds-react-examples/examples/midi-sounds-example4/build)
### List of instruments
Use this.midiSounds.player.loader.instrumentKeys() to get array of drums.
Use this.midiSounds.player.loader.instrumentInfo(i).title to get readable drum name.
[Live example](https://surikov.github.io/midi-sounds-react-examples/examples/midi-sounds-example3/build)

- setBand8k(level)
- setBand16k(level)
[Live example](https://surikov.github.io/midi-sounds-react-examples/examples/midi-sounds-example9/build)
### Cancel all sounds
Use cancelQueue()
### Time
Use contextTime() to get current time of Audio context.
How to calculate musical durations
```
var bpm = 120;
var N = 4 * 60 / bpm;
var duration16th = N/16;
```
### Play drums
- playDrumsAt(when, drums)
- playDrumsNow(drums)

- instrument - number of instrument
- pitches - array of pitches
- duration - durations
### Play beat
```
playBeatAt(when, beat, bpm)
```
- when - time
- beat - array of drums and chords
- bpm - beats per minute
Example of beat array
```
[
[
drum1
,drum2
]
,[
[guitar,[S6+1,S5+3,S4+3],1/4,down]

- guitar, bass - numbers of instruments
- [S6+1,S5+3,S4+3] and [S6+1,S5+3,S4+3] - array with pitches
- 1/4 - duration as part of full note for the bpm
- down - 1|2|3 for strum down, strum up or snap
### Play loop
```
startPlayLoop(beats, bpm, density, fromBeat)
```
