I've built a tool for musicians using modular gear
Hello HN, not many will know what this tool is about, but it's launch day and I always dreamed of posting on HN. Let's start! This is a tool for people using eurorack gear. For synth people. What is cool about my tool is that I show the signal flow with a graph. Here's the official press text: After a decade of stagnation in this space we are excited to present patcher.xyz: the modern way to manage everything modular. It’s a tool for professionals, enthusiasts, and casual wigglers. Novadays artists must develop their own means of taking notes, often on paper, since there is no common format…
I've built a tool for musicians using modular gear launched on February 2, 2022 with 53 votes, #907 of 2,645 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 4 years on.
In plain words
Patcher.xyz is a digital tool for musicians who work with eurorack modular synthesizers. It lets users document and organize their patches by visualizing signal flow as graphs, replacing the traditional method of hand-written notes. The platform addresses the lack of a standard format for sharing modular setups, making patches searchable, editable, and easily shareable among musicians and gear enthusiasts.

From the sources
Free open-source workspace for Eurorack musicians to capture ideas, plan racks, and return to patches quickly.
Patcher aims to be the most comprehensive manager and database for modular gear, providing free access to public data. The project is open-source and available to everyone for free. If you notice a missing module, you can add it yourself using the "Submit New Module" button located in the modules section at the top right of the page. If panel images are missing for a module, you can upload them directly via the module’s detail page. Just navigate to the module page, and you’ll find the option to add images there. Yes, partially. Export your rack as JSON from ModularGrid (requires a Unicorn account), then in the rack creator toggle "Import from ModularGrid" and upload that file. We'll match…from patcher.xyz

Originally started as a project to restore patterns from now defunct website 808.pixll.de just for myself, but eventually i decided to share it with others. I've seen this website mentioned a couple of times on HN:) Currently it only supports Roland TR-808, but there will be more.

PatchMyGear – a living map for your studio gear (cables and checklist)Dec 2025 · patchmygear.com · ▲11Hello HN, I’m a hobby music producer with a changing studio setup and got tired of losing track of what’s patched where (especially after gear swaps). I built PatchMyGear, a website to map audio setups / routing and generate a cable list + wiring checklist, save / load locally. (no signup) Let me know what you think. Happy holidays!
- IFImproved freemusicdemixer – AI music demixing in the browser2023 · freemusicdemixer.com · ▲160
Hi HN, Last time I showed free-music-demixer, which people seemed to enjoy. It was a static website with a Javascript + WASM module to perform music demixing (or music source separation) using an AI model UMX-L (Open-Unmix) running client-side in the browser. Since then, I have overhauled the project and made several improvements: - The demixing/separation quality is higher now, since I implemented the missing post-processing step - Memory usage is lower now by performing a custom segmented inference with a streaming LSTM, which should allow larger tracks (or, dare I say,…

Hi Hacker News, This is definitely out of my comfort zone. I just wanted to show you guys because I'm super proud of it. It's a 100% faithful recreation based off of the schematics, patents, and ROMs that were found online. So please watch the video and tell me what you think https://youtu.be/auOlZXI1VxA The reason why I think this is relevant is because I've been a programmer for 25 years and AI scares the shit out of me. I'm not a programmer anymore. I'm something else now. I don't know what it is but it's multi-disciplinary, and it doesn't involve writing code myself--for…
