How to build a VST plugin or synth with AI

Short answer: Describe the sound and the controls you want, have a coding agent build it with JUCE (the usual C++ framework for VST and AU plugins) or as a browser synth first, then load it in your DAW and tune it by ear. People below include a non-coder who built a working VST plugin with Claude, grew a one-prompt Serum-style wavetable synth into an open-source groovebox that runs in the browser and as a JUCE plugin, had Gemini build a Jupiter-8-style clone that Claude then fine-tuned, with presets made from the original manual, made a VST instrument with Grok Bot, and had Codex build a softsynth with MCP support and then play it live in Reason. Test every build at low volume first, since a DSP bug can produce very loud noise.

Get started in 3 steps

Start with a browser prototype (Web Audio) to get the sound right, then ask the agent to port the same DSP to a JUCE VST3 or AU plugin.
Give the agent reference audio or a manual for the sound you're after and ask it to compare its output, as the Jupiter-8 clone builder did.
Keep your monitors low and add a limiter while testing, because a bad filter or feedback loop can be painfully loud.

Grow a one-prompt wavetable synth into a browser and DAW groovebox

mgeorgi started with one Claude prompt for a Serum-style wavetable synth and expanded it into an open-source groovebox with a synth, drum synth, 303-style bassline and clip launcher that runs in the browser and as a C++/JUCE plugin with the same DSP.

Have an agent synthesize a techno kick drum from pure code

FlorianoRighett asked Grok Bot for a techno kick and it built one from scratch with no samples or DAW: a sine sweeping from 180 to 48 Hz, a click on the attack and a touch of saturation.
