Codex drives a VCV Rack synth live over MCP in an AI-performed patch demo
gabrielchua · x · 2026-09-23
- Developer @sound4movement demoed real-time music generation: a "GPT-6 Sol" model (not a confirmed official OpenAI name) handled high-level reasoning, patching, mixing and performance planning, with Codex executing the automation.
- Codex controls layer levels and effects on VCV Rack through an MCP bridge, generating the sound live rather than playing back a recording.
- The author notes VCV Rack has a free version he has used for years — a striking showcase of agents driving external tools via MCP.
