NodeJS client library for Allen & Heath QU series mixers

Travis Maintainability npm version npm installs dependencies

Table of Contents

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

$ npm install @epegzz/node-qu-client

Example

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()
