Showmaster Pro is an all-in-one embedded show controller that offers all the show protocol interfaces you need. Control and synchronize dimmers, lighting desks, video projectors, video servers, sound processors, etc. You can also call on 16 digital inputs, 16 relay outputs, and balanced Timecode input/output with video reference.

Work with multiple timelines for synchronized show programming. An easy drag-and-drop interface lets you build up to 10 custom HTML touch screen (WebPanel) interfaces. Showmaster Pro supports third party networked Serial, I/O, Infrared, MIDI, and DMX interfaces.

OpenCapXML plugin for Unity

For interactive games or generative media applications, Unity® programmers can access Tasks and Variables in Medialon show control systems using the OpenCapXML plugin for Unity®.

This plugin makes it easy for Unity programmers to link to Medialon Manager and Showmaster projects to trigger tasks, update variable values in the Medialon project, and subscribe to variable value updates from the Medialon project.

With the OpenCapXML plugin for Unity, Medialon control systems become a bridge between the virtual (Unity®) world and the physical world where devices (such as lighting equipment, audio playback, fans, smell generators, heat lamps, water misters, vibration transducers, and video projection/displays) can all work together to tell an interactive story using a built environment, and can even be pre-programmed and debugged before sending to site by mocking it up in the virtual environment.

For more information or to request access to the OpenCapXML plugin for Unity, contact us.

* Please note that while Medialon Manager V7.1 is compatible with Showmaster Pro and Showmaster LE hardware, only more recent models have the required motherboard in them. The upgrade is a paid upgrade that requires additional hardware to be installed. Eligible Showmasters can be sent to 7thSense to be upgraded, but the upgrade is not something which can be performed by end users or systems integrators. Please contact our sales team at for more information and to enquire about compatibility of your Showmaster hardware with Medialon Manager 7.1.
