The 0.7 profiles were created with LED Volume pixel mapping in mind and what is known as Image Based Lighting. When pixel-mapping DMX data, the RGB values that you're sending to the lights are set in a certain Color Space, which is usually defined by how that video media was transcoded (i.e. Rec709, sRGB, etc). With firmware v0.7, you can now control the Color Space of the light to match the playback media with a single DMX parameter as part of the Global Parameters in our new pixel mapping profiles.

These Color Spaces are found in the new VRGB (Video RGB) and RGBVW (RGB Variable White) dmx profiles.

With RGBVW profiles, it is per-pixel control over RGB, CCT and +/- Green, with per-fixture control of Global Parameters such as Spectrum, Color Space and Output level.

With VRGB profiles, we move CCT and +/- Green into the Global Parameter column to minimize the dmx footprint of the profile.

Note: Color Spaces make use of the Relative Colorimetric color engine explained below.

Absolute Hue is our native RGBX color engine that gives you the maximum capabilities of the LED diode set where we maximize Saturation and Brightness. When this color engine is at 100% Saturation the Color Temperature (CCT) has no bearing on the light's color output. You are getting the maximum saturation the LED's can produce. This is how manufacturers traditionally saturate light inside their fixtures.

The Relative Colorimetric engine is x/y calibrated. So when the light is 100% saturated the color temperature (CCT) is calculated into final output. This means when you're changing the Color Space parameter to Rec709, sRGB or Linear, you are in this new Relative Colorimetric engine where we maximize SSI (Spectral Similarity Index) within the color space you've selected.

Finally, we've merged all this into a new VRGB profile (Profile 62) that has just Red, Green and Blue locked to a whitepoint of D6500 in the Rec709 gamut while giving you the Relative Colorimetric engine (X/Y under the hood) in a simple RGB profile.  So you can get all the color engine benefits and also maximize fixture-count per universe of DMX at the same time.

Why is all this important?

When receiving video footage that will be output to your lights, you may not know what Color Space that footage was transcoded in.  So you can now change the Color Space of the lights on the fly via a single DMX parameter.  This means more accurate and more precise color reproduction from your pixel-mapped media.

Now with 0.7, you have the ability to update your RR and RR 2's CRMX chip over USB.

This simplifies the update process where you no longer need to update each light individually over Bluetooth. (But you still can if you need to)

When you download the 0.7 update, also download the TimoTwo file from our site.  Copy both files onto a USB-C Drive and put the light into Update Mode. After it updates to firmware v0.7, the light will reboot and let you know it found a new TimoTwo firmware and automatically update.

Then you can be up and running with CRMX2 for the Stardust. All future TimoTwo updates will be that simple. Click here for More info
