The simplest drum pattern composing algorithm I could come up with
Hi there, my name is Jay. Making music and writing software have probably been the two biggest pleasures of my life -only after my family. My team and I recently started a long journey of trying to completely change the way people create music, and as it usually happens with any long journey, it all starts with small steps. One of those small steps was to build https://drummy.io, or "Dummy Drums," a very simple yet useful drum machine that stores the entire drum pattern in the hashtag of the URL. There is no backend. Fully served by a CDN. If you wanna learn how to build your own…

In plain words
Drummy Drums is a simple web-based drum machine that lets users create and share drum patterns entirely through the URL, with no backend required. It stores patterns in the hashtag portion of links and runs entirely on CDN infrastructure. The tool is designed for musicians and developers interested in creating drum beats and learning how to build audio applications using JavaScript and the Web Audio API.

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.
I made a generative online drum machine with ClojureScript2025 · dopeloop.ai · ▲202After 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…
Beats, a web-based drum machineJan 2026 · beats.lasagna.pizza · ▲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,…

A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc. The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly. This model can be used to disrupt any marketplace from AirBNB to UberEats: building tech for home renters and restaurants and later, leveraging that to build a competing…
