Interactive Performance Controller for a Violin. A visual interface that merges classical instrument control with fluid animation and 3D rendering.

The idea was to design a violin controller that feels organic and alive. Not like a technical interface, but like an instrument itself. The four control sliders should appear as if they emerge from nothing, rising out of white liquid and taking shape. No hard UI look. Instead, matter that forms itself.

Each slider controls a distinct sound parameter of the violin:

Bow Pressure Pressure of the bow on the string, ranging from delicate to intense.

Tone Color Timbre shifting between warm, dark, bright, and brilliant.

Vibrato String vibration controlling depth and speed.

Reverb Room sound moving from dry to expansive and cathedral-like.

All four sliders are fully interactive. Users can drag them in real time and visually influence the sound landscape.

The violin at the heart of the interface was modeled and rendered in Blender, exported as a PNG sequence, and integrated directly into the animation. It stands at the center. Everything revolves around it.

Behind the violin, subtle color elements react to the position of each slider.

Bow Pressure shifts intensity and density. Tone Color moves across the color spectrum. Vibrato generates soft wave-like motion. Reverb makes the background softer, more diffused, more atmospheric.

The violin lives visually. You see what you control.

Individual parameters can be muted, allowing focused control and clear isolation of single sound layers.

Animation and Interaction Rive. All inputs connected to state machines.

3D Violin Rendering Blender. Rendered and exported as PNG sequence.

Fluid Slider Animation Rive. White liquid emergence effect.

Interactive Controls Rive Inputs. Real-time slider manipulation.

Visual Feedback Animated color layers responding to each parameter.

Mute Toggle Rive state machine. Per-parameter mute control.

This was one of my first projects in Rive from early 2025. An exploration piece. The goal was not to build a production-ready music tool. The goal was to test a question.

How far can you push visual animation and interactive connection in a single interface? How much can you animate, how much can you connect, how much can you make a user feel that they are touching sound instead of just clicking buttons?
