JackWithOneEye/node-modules — reverse-engineered prompt

Build me a web based modular synthesizer app called node modules. I want to open it in the browser and make sounds by adding synth modules to a workspace, then connecting them together like a simple patch bay. Start with the basics, an oscillator, gain or volume control, filter, envelope, output, and maybe a small keyboard or note trigger so I can actually hear it. The interface should feel friendly, with draggable modules, visible cables or connections, and clear controls for knobs and sliders.

Use Vue for the app since that seems to be the direction here, and put the audio work in the audio processors area if needed. Keep it simple enough to run locally, with a clean layout, useful defaults, and no confusing setup. Please include a short README update with how to install, start, and use it. If you need current browser audio docs, look them up online.
