I keep meaning to experiment with vibe-coded VSTs. The shell and UI parts should be easy to automate, because they're basically boilerplate. But I doubt AI knows enough about DSP to design an incredible new reverb algorithm, or is an expert on bandwidth-limited oscillator design.
Or maybe it is? When I have some time, I'll find out.
I'm sure it could replicate any existing algorithm or riff on combinations, but a good plugin is made carefully by hand by an artisan who knows what they are looking to achieve, who knows what to listen for. I'm skeptical that a pure AI algorithm would be anything but plagiarism on existing designs.
