What Is the ONYX Essential Key?
The ONYX Essential Key is a USB dongle that acts as a software license activator for ONYX lighting control software by Obsidian Control Systems. When plugged into a PC running ONYX, the Essential Key unlocks enhanced functionality, allowing you to expand the software beyond its free feature set.
Unlike traditional software that limits users behind account restrictions or subscriptions, the ONYX Key system provides a hardware-based license, ensuring portability, reliability, and freedom from online activation hassles.
ONYX Software: A Quick Primer
ONYX is a powerful, flexible lighting control platform designed for professionals across entertainment, theater, live music, corporate events, and installations. It supports:
- DMX lighting
- Art-Net and sACN
- Visualizers
- Touchscreen controls
- MIDI, OSC, and timecode inputs
The ONYX platform can be downloaded and used for free in Basic Mode, which allows limited universes and basic features. However, to unlock more DMX universes, advanced effects, cue lists, and integration tools, a license is required — that’s where the Essential Key comes in.

What Does the ONYX Essential Key Unlock?
Here’s what you gain by plugging in the ONYX Essential Key:
✅ 2 Universes of Output (DMX, Art-Net, or sACN)
The key unlocks 2 fully licensed universes of output. This is ideal for small shows, churches, corporate events, or mobile DJs who need reliable, no-lag DMX control.
✅ Advanced Software Features
With the Essential license, you unlock enhanced features including:
- Unlimited cue lists
- Complete parameter control
- Advanced patching and grouping

- MIDI controllers
- OSC (Open Sound Control)
- Remote apps
- Timecode triggers
This opens the door for synchronized shows, live performances, and complex interactive setups.

Design and Build: Compact, Rugged, Reliable
The ONYX Essential Key is built like a typical USB flash drive but with robust construction designed for road use. It’s:
- Small enough to carry in a pocket or toolkit
- Durable to withstand gigging and travel
- Clearly labeled for identification
It doesn’t require power or drivers — simply plug it in and ONYX will detect the license instantly. This simplicity is a huge advantage for on-the-go professionals.
Why Use a USB Dongle for Licensing?
Software keys that are locked to a machine or cloud account can be inconvenient and unreliable in live performance environments. The ONYX USB system offers several critical benefits:
🔒 Security & Portability
Your license isn’t tied to a single PC. If your main system fails, just plug the key into a backup system and go.
📶 No Internet Required
The key works offline — crucial for festivals, theater venues, or rural locations with poor internet access.
🔁 Reusable & Transferable
Reassign licenses between machines easily by moving the USB dongle — no need to contact support or reinstall.
