After two years of development, I'm super excited to release Beat Maker! This is my take on what I hope is the best free, web-based drum machine. My goal was to build something that was not only fun and easy to use for beginners but also powerful enough for serious producers. I did extensive research on existing drum machines, analyzed their UX, and tried to build something that adds something new. It's a nearly 100% client-side app, written in ClojureScript, and is a PWA so you can install it to your home screen for an app-like experience. Besides the standard grid editor, Beat Maker has…

I built a synthesizer based on 3D physicsfree tier, from $99/mo▲512I've been working on the Anukari 3D Physics Synthesizer for a little over two years now. It's one of the earliest virtual instruments to rely on the GPU for audio processing, which has been incredibly challenging and fun. In the end, predictably, the GUI for manipulating the 3D system actually ended up being a lot more work than the physics simulation. So far I am only selling it direct on my website, which seems to be working well. I hope to turn it into a sustainable business, and ideally I'd have enough revenue to hire folks to help with it. So far it's been 99% a solo project, with…

Beats, a web-based drum machinefree▲160Hello all! I've been an avid fan of Pocket Operators by Teenage Engineering since I found out about them. I even own an EP-133 K.O. II today, which I love. A couple of months ago, Reddit user andiam03 shared a Google Sheet with some drum patterns [1]. I thought it was a very cool way to share and understand beats. During the weekend I coded a basic version of this app I am sharing today. I iterated over it in my free time, and yesterday I felt like I had a pretty good version to share with y'all. It's not meant to be a sequencer but rather a way to experiment with beats and basic sounds,…

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.

Haxophone▲526I built this during Covid. When I released it, some of the parts went out of stock or skyrocketed in price, no longer making this an economic DIY project. Now that things are getting back to almost normal, I thought I'd share it here and request feedback. This is a very niche project for people who like the same things I do: saxophones, Rust, mechanical keyboards and the Raspberry Pi.

Inspired by the recent Boards Of Canada announcement, I've been in a low-fi electronica mood lately and was going back and forth with Claude on how to design similar instruments in the browser that fit the genre. One thing led to another and pretty soon I had a fully browser based polyphonic synthesizer / drum machine / sequencer. The interface and workflow was heavily inspired by the Rebirth338 application released back in the 90's, but with lo-fi synth voices rather than the original 303 & 808 emulation. I know there's a significant overlap of developers and musicians and I…
