# JZZ: MIDI library for Node.js and web-browsers
[](https://www.npmjs.com/package/jzz)
[](https://www.npmjs.com/package/jzz)
[](https://www.jsdelivr.com/package/npm/jzz)
[](https://github.com/jazz-soft/JZZ/actions)
[](https://coveralls.io/github/jazz-soft/JZZ?branch=master)
[](https://npm.runkit.com/jzz)
**JZZ.js** allows sending, receiving and playing MIDI messages
in **Node.js** and **all major browsers**
in **Linux**, **MacOS** and **Windows**.
Some features are available on **iOS** and **Android** devices.
**JZZ.js** enables [**Web MIDI API**](https://webaudio.github.io/web-midi-api/)
in **Node.js** and those browsers that don't support it,
and provides additional functionality to make developer's life easier.
For the best user experience, it's *highly RECOMMENDED (though not required)*
to install the latest version of [**Jazz-Plugin**](https://jazz-soft.net)
and browser extensions from [**Chrome Web Store**](https://chrome.google.com/webstore/detail/jazz-midi/jhdoobfdaejmldnpihidjemjcbpfmbkm)
or [**Mozilla Add-ons**](https://addons.mozilla.org/en-US/firefox/addon/jazz-midi)
or [**Apple App Store**](https://apps.apple.com/us/app/jazz-midi/id1506447231).
## Features
- MIDI In/Out
- User-defined MIDI nodes
- MIDI files
- MPE
- SMPTE
- UMP (MIDI 2.0)
- Additional modules
## Install
`npm install jzz --save`
or `yarn add jzz`
or get the full development version and minified scripts from [**Github**](https://github.com/jazz-soft/JZZ)
*Note:* in the (unlikely) case you get into trouble installing the
[**midi-test**](https://www.npmjs.com/package/midi-test) module,
that requires special system configuration,
you can safely remove it from the *devDependencies*
by running `npm remove midi-test --save-dev`.
## Usage
##### Plain HTML
```html
//...
```
##### CDN (jsdelivr)
```html
// the latest version, or
// any particular version
//...
```
##### CDN (unpkg)
```html
// the latest version, or
// any particular version
//...
```
##### CommonJS
```js
var JZZ = require('jzz');
//...
```
##### TypeScript / ES6
```ts
import { JZZ } from 'jzz';
//...
```
##### AMD
```js
require(['JZZ'], function(JZZ) {
//...
});
```
## Web MIDI API
##### (Node.js example)
```js
var navigator = require('jzz');
navigator.requestMIDIAccess().then(onSuccess, onFail);
// ...
navigator.close(); // This will close MIDI inputs,
// otherwise Node.js will wait for MIDI input forever.
// In browsers the funcion is neither defined nor required.
```
## JZZ API
##### MIDI Output/Input
```js
JZZ().or('Cannot start MIDI engine!')
.openMidiOut().or('Cannot open MIDI Out port!')
.wait(500).send([0x90,60,127]) // note on
.wait(500).send([0x80,60,0]); // note off
JZZ().openMidiIn().or('Cannot open MIDI In port!')
.and(function() { console.log('MIDI-In: ', this.name()); })
.connect(function(msg) { console.log(msg.toString()); })
.wait(10000).close();
```
##### Connecting MIDI nodes
```js
var input = JZZ().openMidiIn();
var output = JZZ().openMidiOut();
var delay = JZZ.Widget({ _receive: function(msg) { this.wait(500).emit(msg); }});
input.connect(delay);
delay.connect(output);
```
##### Helpers and shortcuts
```js
// All calls below will do the same job:
port.send([0x90, 61, 127]).wait(500).send([0x80, 61, 0]); // arrays
port.send(0x90, 61, 127).wait(500).send(0x80, 61, 0); // comma-separated
port.send(0x90, 'C#5', 127).wait(500).send(0x80, 'Db5', 0); // note names
port.noteOn(0, 'C#5', 127).wait(500).noteOff(0, 'B##4'); // helper functions
port.note(0, 'C#5', 127, 500); // another shortcut
port.ch(0).noteOn('C#5').wait(500).noteOff('C#5'); // using channels
port.ch(0).note('C#5', 127, 500); // using channels
```
##### Asynchronous calls
```js
// in the environments that support async/await:
async function playNote() {
var midi = await JZZ();
var port = await midi.openMidiOut();
await port.noteOn(0, 'C5', 127);
await port.wait(500);
await port.noteOff(0, 'C5');
await port.close();
console.log('done!');
}
// or:
async function playAnotherNote() {
var port = await JZZ().openMidiOut();
await port.noteOn(0, 'C5', 127).wait(500).noteOff(0, 'C5').close();
console.log('done!');
}
```
##### Virtual MIDI ports
```js
var logger = JZZ.Widget({ _receive: function(msg) { console.log(msg.toString()); }});
JZZ.addMidiOut('Console Logger', logger);
// now it can be used as a port:
var port = JZZ().openMidiOut('Console Logger');
// ...
// substitute the native MIDIAccess
// to make virtual ports visible to the Web MIDI API code:
navigator.requestMIDIAccess = JZZ.requestMIDIAccess;
```
##### Frequency / MIDI conversion
```js
JZZ.MIDI.freq('A5'); // => 440
JZZ.MIDI.freq(69); // => 440
JZZ.MIDI.freq(69.5); // => 452.8929841231365
// from frequency:
JZZ.MIDI.midi(440); // => 69
JZZ.MIDI.midi(450); // => 69.38905773230853
// or from name:
JZZ.MIDI.midi('A5'); // => 69
```
## MIDI 2.0
`MIDI2()` is an adapter that enables MIDI 2.0 in all subsequent chained calls.
`MIDI1()` returns the operation back to MIDI 1.0.
Note that the downstream MIDI nodes don't require any special actions to receive and transfer MIDI 2.0 messages:
```js
var first = JZZ.Widget();
var second = JZZ.Widget();
var third = JZZ.Widget();
first.connect(second);
second.connect(third);
third.connect(function (msg) { console.log(msg.toString()); });
first
.send([0x90, 0x3c, 0x7f]) // 90 3c 7f -- Note On
.MIDI2() // enable MIDI 2.0
.send([0x20, 0x90, 0x3c, 0x7f]) // 20903c7f -- Note On
.MIDI1() // reset to MIDI 1.0
.send([0x90, 0x3c, 0x7f]) // 90 3c 7f -- Note On
```
When used with MIDI 2.0, most of MIDI 1.0 helpers require `group` as an additional first parameter
and produce MIDI 1.0 messages wrapped into UMP packages.
Most of the new MIDI 2.0 helpers don't have corresponding MIDI 1.0 messages.
Use `gr()`, `ch()` and `sxId()` calls to set default `group`, `channel` and `SysEx ID` for the subsequent calls.
`MIDI2()` and `MIDI1()` clear off default `group`, `channel`, `SysEx ID` and `MPE` settings:
```js
first
.noteOn(5, 'C5', 127) // 95 3c 7f -- Note On
.ch(5).noteOn('C5', 127) // 95 3c 7f -- Note On
.MIDI2()
.noteOn(2, 5, 'C5', 127) // 22953c7f -- Note On
.gr(2).noteOn(5, 'C5', 127) // 22953c7f -- Note On
.ch(5).noteOn('C5', 127) // 22953c7f -- Note On
.MIDI2()
.noteOn(2, 5, 'C5', 127) // 22953c7f -- Note On
.ch(5).noteOn(2, 'C5', 127) // 22953c7f -- Note On
.MIDI2()
.umpNoteOn(2, 5, 'C5', 127) // 42953c00 007f0000 -- Note On
.gr(2).umpNoteOn(5, 'C5', 127) // 42953c00 007f0000 -- Note On
.ch(5).umpNoteOn('C5', 127) // 42953c00 007f0000 -- Note On
```
