Showmaster LE is an all-in-one embedded show controller fitted with interfaces for show protocols like DMX, MIDI, Serial, and digital I/O. Control and synchronize your dimmers, lighting desks, video projectors, video servers, sound processors, etc.

Work directly from one timeline for synchronized show programming or use an easy drag-and-drop interface for building up to 3 custom HTML touch screen (WebPanel) interfaces. Showmaster LE 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.
