How does Mixstein actually talk to Claude? Does it call tools?

For months you've watched me build MIXSTEIN in front of you — an AI that doesn't just talk about your mix, it opens Ableton and makes the moves. Real devices. Real settings. On your session, not in some cloud demo. Last week I watched it read a record against a J Dilla instrumental, tell me exactly where the mids were lying, and prescribe the moves — and when it had nothing worth fixing, it said nothing. That's the part that took the longest to build: a tool with restraint. Tools that make moves are everywhere. Tools that know when NOT to are not. Here's where it stands: MIXSTEIN is going out very, very soon — but not wide. First it goes into the hands of a small group of creators while I'm personally on the line with each of them. They stress it, break it, shape it. Then it expands from there. Then the real thing arrives for everybody else — and by then it'll have been battle-tested by people who actually mix. If you've been waiting for the moment to pay attention, this is it. Question for the room: if MIXSTEIN could take ONE thing off your plate the first time you open it — what would you pick? Answers here genuinely shape what the first group gets.
