Installation

$ npm install --save xkeys

Getting started

JavaScript

 
const XKeys = require('xkeys');
 
var myXkeysPanel = new XKeys();
 
// Listen to pressed keys:
myXkeysPanel.on('down', keyIndex => {
    console.log('Key pressed: '+keyIndex);
    myXkeysPanel.setBacklight(keyIndex, true);
});
// Listen to released keys:
myXkeysPanel.on('up', keyIndex => {
    console.log('Key released: '+keyIndex);
 
    myXkeysPanel.setBacklight(keyIndex, false);
});
 
// --- Experimental functions ---
// The functions below are implemented, but not tested with any hardware yet.
//
 
myXkeysPanel.on('jog', deltaPos => {
    console.log('Jog position has changed: '+deltaPos);
});
myXkeysPanel.on('shuttle', shuttlePos => {
    console.log('Shuttle position has changed: '+shuttlePos);
});
myXkeysPanel.on('joystick', position => {
    console.log('Joystick has changed:'+position); // {x, y, z}
});
 

Documentation

Initalize

Connect to any connected X-keys panel

const XKeys = require('xkeys');
 
var myXkeysPanel = new XKeys();

Connect to a specific X-keys panel

const HID = require('node-hid');
const XKeys = require('xkeys');
 
const devices = HID.devices();
const connectedXKeys = devices.filter(device => {
    return (device.vendorId === XKeys.vendorId && device.usage === 1); // Make sure that the usage-property is set to 1
});
 
if (connectedXKeys.length) {
    var myXkeysPanel = new XKeys(connectedXKeys[0].path);
} else {
    console.log("Could not find any connected X-keys panels.");
}
 

Events

  • 'downKey' & 'upKey': Triggered when a regular button is pressed/released. Emitted with (keyIndex).

  • 'downAlt' & 'upAlt': Triggered when an alternative button is pressed/released, such as the "program switch" (keyIndex 'PS'). Emitted with (keyIndex).

  • 'down' & 'up': Triggered when ANY button is pressed/released. Emitted with (keyIndex).

  • 'jog': Triggered when the jog wheel is moved. Emitted with (jogValue)

  • 'shuttle': Triggered when the shuttle is moved. Emitted with (shuttleValue)

  • 'joystick': Triggered when the joystick is moved. Emitted with ({x, y, z})

  • 'error': Triggered on error. Emitted with (error).

Setting things

Set backlight of a button

.setBacklight(keyIndex, on, redLight, flashing);
 
// Examples:
// Light up the backlight of bank 1 (blue light)
.setBacklight(keyIndex, true);
// Flash the backlight of bank 2 (red light)
.setBacklight(keyIndex, true, true, true);

Set the LEDs (the red/green status LED's)

.setLED(keyIndex, on, flashing)
 
// Examples:
// Light up the green LED
.setBacklight(0, true);
// Light up the red LED
.setBacklight(1, true);

Set backlight intensity

.setBacklightIntensity(intensity)
 
// Example:
// Set max intensity
.setBacklightIntensity(255)

Set all backlights on or off

.setAllBacklights(on, redLight)
 
// Example:
// Light up all buttons
.setAllBacklights(true, false)
.setAllBacklights(true, true)

Set flashing frequency

// The frequency can be set to 1-255, where 1 is fastest and 255 is the slowest.
// 255 is approximately 4 seconds between flashes.
.setFrequency(frequency)
 
// Example:
// Set the frequency to a pretty fast flash
.setFrequency(8)
