Ultimate Guide to Setting Up DMX Pixel Lights with MadMapper & Holiday Coro

Comprehensive Article on Setting Up and Programming DMX Controllable Pixel Lights with MadMapper


Setting up a dynamic stage lighting system using DMX controllable pixel lights can transform any performance space into a visually captivating scene. This tutorial dives into the intricacies of programming and controlling pixel lights using the HolidayCoro AlphaPix controller and MadMapper software, focusing on a stage setup to demonstrate the application.

Equipment and Initial Setup

The setup involves pixel lights sourced from, which are akin to RGB controllable Christmas lights where each pixel is individually addressable via DMX protocols. These lights are arranged on a stage, encased within white tubes to create a cohesive aesthetic. At the heart of the control system is the HolidayCoro AlphaPix (‘the brain’), capable of managing multiple outputs and pixel configurations.

Wiring and Configuration

The physical setup starts with arranging the pixel lights in desired patterns, in this case, a diagonal layout across the stage. The AlphaPix controller supports up to 100 pixels per output, with the configuration used here involving chains of 50 pixels linked to make strands of 100. The wiring is meticulously planned to ensure smooth data flow and ease of installation, with clear demarcations for data direction and connectivity.

Software Setup and Programming

MadMapper software plays a crucial role in animating the pixel lights. It interfaces with the AlphaPix controller via an IP network, utilizing the ArtNet DMX transfer protocol. The first step involves assigning an IP address to the controller and configuring the ports to align with the number of pixels in each channel. Each port on the AlphaPix can manage up to 100 pixels, translating each pixel into three DMX channels to accommodate the RGB controls.

The configuration within MadMapper involves mapping these ports and channels into the software’s interface, where each physical line of pixels is treated as a fixture. This is crucial for syncing the lighting effects with the desired visual outputs on the stage.

Scene Building and Effects

With the hardware configured and recognized within MadMapper, the next step involves building scenes. This process includes aligning each pixel row with the corresponding DMX addresses set in the AlphaPix controller, ensuring that the data flow from the controller to the lights is seamless and accurate.

The MadMapper interface allows for detailed control over the lighting effects, from basic color changes to complex patterns that traverse through the pixel rows. These effects can be pre-programmed and triggered according to the specific needs of the performance or event.

Practical Application and Final Thoughts

The tutorial covers practical steps, from wiring to programming, ensuring that even those new to DMX lighting can follow along. The flexibility of the system allows for creative configurations beyond simple straight lines, enabling designers to tailor the setup to the venue’s architectural elements and the event’s thematic requirements.

This detailed setup showcases the potential of integrating sophisticated DMX lighting systems with modern software to create an immersive visual experience. The combination of HolidayCoro’s reliable hardware and MadMapper’s versatile software makes for a powerful tool in any lighting designer’s toolkit.
