Exploring Analog RGB

In this demo, I’m playing around again—improvising on the piano and watching how the lights respond.

But this time, instead of simple LED strips, the output is being sent to a 4x3 array of 16x16 LED grids. All of these are split from a single MAINFRAME unit, duplicated, and each column is rotated.

We’re still modulating based on pitch and velocity, but now you’re seeing it across a much larger canvas. Each preset here defines a sort of “box”—a visual language or mood. Within that box, modulation adds fluid variation—dynamics that bring it to life.

The goal is to explore how a digital system like MAINFRAME can produce visuals that feel organic—alive—despite being rooted in logic and repetition.

What’s interesting is that even though these grids are all mirrored and duplicated, when you watch them over time, they start to form larger, more complex structures—almost like cells forming a multi-cellular organism. Each grid is identical in function, but together they behave like parts of a whole.

As with the previous demo, I don’t plan what I’m going to play. I just experiment. I observe how the visuals behave, how patterns evolve, how modulation changes the flow. The lights guide the performance just as much as the music does.

MAINFRAME is designed to support this kind of feedback loop—where sound influences light and light, in turn, shapes how you play. It’s about creating expressive, reactive systems that feel alive.

And this grid setup really emphasizes that—how complexity can emerge from simple, repeated elements. It’s an experiment in structure, symmetry, and surprise.

That’s something I want to keep exploring: how digital tools can be used to create visual systems that aren’t just reactive, but expressive—systems that invite you to play.
