Sound to Light: To RIO-A or not to RIO-A, that is the question...

Hi there,

I am about to program an interactive light installation for a small stage. The light canopy above the stage I've designed is supposed to be interactive with the music on the stage below. The music is live, doesn't have a timecode, and changes daily.

The light installation is controlled by an MSC4. Can the MSC's analog inputs function as audio inputs, let's say 4 different bands or would I need a dedicated RIO-A connected to the MSC4?

Reading through the RIO-A specs it says:

FEATURES
• Stereo balanced audio input with auto or manual gain adjustment (software adjustable)
• Per channel spectrum analysis with configurable 3–30 band configurable analyzer

Would that mean I only need a stereo input from the sound mixer and then the RIO-A spectrum analyzer in conjunction with Mosaic Designer would let me e.g. split the audio band into 3 bands (low, mid, high frequencies) and then I could trigger different lights accordingly?

Are there any programming examples available or more detailed instructions or audio specific manuals?

Thanks for your help in advance!

Erwin

  • The RIO is still the only way to go in a Mosaic ecosystem without introducing other devices. The challenge is the live aspect, as the RIO input triggers work best when you have enough time to tweak it to the dynamics of your music. You can look at tying variables from your audio input volume to timeline rate and speed up/ slow down your timelines based on volume. However, this is still one of those features that is not a one shoe fits all and will take some on site tweaking.
