## Features

Currently this client can:

* activate PAFL for each channel

* set the fader level for each channel

* activate the mute button for each channel

* shut down the mixer

If you need more features then feel free to open a GitHub issue and I will add them.   

## Prerequisites

### OSX

* Some version of Xcode (or Command Line Tools)

* Python (for node-gyp)

### Windows

* Microsoft Visual C++ (the Express edition works fine)

* Python (for node-gyp)

### Linux

* A C++ compiler

* You must have installed and configured ALSA.

* Install the libasound2-dev package.

* Python (for node-gyp)

## Installation

```bash

$ npm install @epegzz/node-qu-client

```

## Example

```javascript

const Mixer = require('@epegzz/node-qu-client')

// Connect to the mixer.

// The constructor takes one single argument which is the MIDI port name of the mixer.

// If you do not know the port name, just leave it blank. That will cause an error message

// that includes a list of all available ports.

const mixer = new Mixer('QU-16 MIDI In')

// Set volume fader level

// 0% = - infinity db

// 100% = 0db

// 127% = 10db

mixer.setFaderPosition({

  channel: Mixer.channels.main_lr,

  percent: 100

})

// Activate PAFL

mixer.setPaflSelect({

  channel: Mixer.channels.stereo_1,

  active: true

})

// Unmute

mixer.setMute({

  channel: Mixer.channels.input_9,

  active: false

})

// Shut down

mixer.shutdown() 

// Release connection to mixer

mixer.disconnect()

```
