Works with Claude, ChatGPT, Cursor, Zed

Make your AI assistant fluent in Eurorack.

Eurorack Reference is a connector for Claude, ChatGPT, and other AI assistants. It gives your assistant manual-grade answers about every Eurorack module — with the manufacturer's exact words quoted where they matter. No paraphrase, no guessing.

Now your assistant can answer

  • What does the MORPH knob on Plaits do?
  • Find me a 6 HP quantizer under $300.
  • What jacks does Maths have, and what's on each one?
  • Suggest a wavefolder that pairs with Plaits as a complex oscillator.
  • Draw a patch for a self-generating ambient setup.

What it looks like in your assistant

A real exchange. With the manual nearby.

What are the outputs on Maths, and what's the difference between SUM and UNITY?

Tool

get_module("make-noise/maths")

Claude

Maths has several output types. The CH. 1–4 Variable Outputs carry each channel's signal as processed by its attenuverter, and are normalized to the SUM and OR busses. SUM is the analog sum of all four channels through their attenuverters (range ±10 V); OR is the analog-logic OR — the highest instantaneous voltage among channels 1–4 (range 0 V to 10 V); and INV is the inverted SUM.

Channels 1 and 4 additionally have Unity outputs, which differ from SUM in two key ways: Unity is tapped before the attenuverter (so the channel's own knob doesn't affect it), and patching the Unity out does not remove the channel from the SUM/OR busses.

From the Maths Operation Manual, "Signal Outputs > Unity Signal Outs (CH. 1 and 4)":

"These outputs are tapped directly of the core of the associated Channel. They are not affected by the Channel's Attenuverter. Patching into this output does NOT remove the signal from the SUM and OR Buses."

When the exact wording matters, your assistant can quote the manual directly — like the passage above. The rest of the time, it answers in its own words, but with the manual open instead of from memory. Without Eurorack Reference, it's guessing.

What your assistant can do

Five tools, plain-language framing.

Once Eurorack Reference is connected, your assistant gains these five abilities. You don't need to call any of them by name — just ask in your own words.

  1. Look up any module's specs, jacks, and parameters.

    get_module

    What does ADSR length default to on Pamela's NEW Workout?

  2. Quote the manual word-for-word.

    get_manual_chunk

    Show me what the Maths manual actually says about the Unity outputs.

  3. Search by what a module does, not who made it.

    search_modules

    Show me 6 HP quantizers.

  4. Suggest compatible or alternative modules.

    find_compatible_with

    What pairs well with Plaits as a complex oscillator?

  5. Visualize patches and signal flow.

    draw_patch_diagram

    Sketch a self-patched Maths.
