In plain words
Patchcab is a modular synthesizer built using the Web Audio API and Svelte framework. It allows users to create and manipulate sounds by connecting virtual modules in a patch-based interface, similar to hardware modular synthesizers. The tool runs in web browsers and is designed for musicians, sound designers, and developers interested in audio synthesis and experimentation with web-based audio tools.

I've built a tool for musicians using modular gear2022 · patcher.xyz · ▲53Hello 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!

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
