Good question to answer once, publicly. No — MIXSTEIN isn't an agentic harness, and the product doesn't talk to Claude at all. No LLM ships in it. The engine reads your rendered audio, compares it against your reference and my captured decision data, and drives Ableton directly through the remote-script API. Deterministic — same mix, same reference, same answer every time. The Claude you've seen in my videos is my workbench, not the product. I use AI heavily to build MIXSTEIN. MIXSTEIN doesn't need AI to run. That's why it works offline, costs nothing per use, and your records never leave your machine. That's as deep as I'm going on internals before it ships — founders get the real look first. I appreciate people probing. I understand you're not the first. The curiosity is warranted, I get it, but I won't be giving away any specifics as far as like how I build.
