Products that do what I Built a Sequencer for the Web does
Hey HN! Last week I was working on a website and needed a way to synchronise visuals with live music. I've used MIDI controllers for this before, but I am travelling right now and don't have mine with me. So I had the crazy idea to build a browser extension that uses the keyboard as input and includes a sequencer. I gave myself 24 to work on it. It ended up taking longer (of course), specially since I ended up creating a demo, a small landing, docs, and an intro video. Took me one week from idea to launch (pushed quite a bit tbh). Features: - Works as a browser extension. Atm distributed…

Try it at: ssh krnl.duetbrowser.com No sign up, totally free - no download. Let me know what you think. Prior art exists (brow.sh) but I wasn't satisfied with their graphical take. I wanted the raw, old skool terminal days of the early internet - BBS, and old green phosphor library comptuers - but running the modern web, with all the bells and jingle jangle whistles (JavaScript, etc). No funding, no VC, just 100% raw terminal fun. Not sure how long the demo will last, but try it out.

Hey everyone, I've built a multiplayer audio recorder/looper for songwriting in your browser. It started as a side project in March last year but 3 months ago I quit my job to work on it full-time. I wanted the simplicity of a Portastudio and the utility of a loop station to serve as an easy way to get song ideas together without needing to send files back and forth, or get lost in the complexity of traditional DAWs up front - just record or upload your ideas and share the link with whoever you want to collaborate with. Would love to hear what you think of it! Any feedback, thoughts, or…

You know that old TI calculator you used in high school, then put in a box and forgot about? Have you ever wished you had an operating system for your calculator with preemptive multitasking, dynamic memory management, a tree filesystem conforming to the FHS, and all the comforts of Unix? Well, good news: that's totally a thing that exists. I've been working on my kernel for about three and a half years now and I'm looking for new contributors to help out. It's written entirely in z80 assembly, and it's both challenging and fun to work on. There's an IRC channel for contributors or people…

Hey y'all, So - the main idea of this is to make a WebAudio synthesis/sequencer tool which humans can use via the UI, but where the big unlock is for agents to drive with MCP It's semi decent as "make a groovy jazz track", especially for retro sounds - but the real use case is more like "make a jetpack whoosh effect I can control via code at runtime - where the sound changes based on character health or how much fuel is left" In other words, the target audience is not musicians (except maybe of the Max/MSP sort), but more like creative coders who want to shape the sound iteratively…

Hello HN! It seems there has been an influx of MIDI projects as of late. I myself also got inspired to work on one last January. I had become frustrated in not being able to read my old sheet music without counting the notes mentally. I thought there had to be an easier way to learn them, I surveyd some apps but none of them felt right to me. So I decided to build one myself and learn some music theory too. I'm quite happy how it turned out, in the end. My sheet-reading has improved substantially although playing and remembering notes is two different things. It works best if you use MIDI…

So, I've never written a line of Rust in my life. I wouldn't know an `&mut this` from a mutandis. But I saw a tweet about a month ago that said, in this new era of AI, you'd be able to just take a library that you love, throw a TUI around it, and call it an app. So I spent about 200 bucks last month, here's what I came up with: Imbolc is a DAW that runs entirely in your terminal. It talks to scsynth over OSC and ships 58 instruments and 39 effects. VSTs are a work in progress, also GarageBand loops if you want to recreate "Umbrella". The codebase is about 60k? lines of Rust across 5 crates,…

I know mentioning Michael Seibel is almost cheating, but this week he demonstrated the "leaky pipes" concept to me. Not that I know the guy, but in one of his videos he says something on the lines of "If you are unsure if you app is ready to be launched, just launch it. It's like a house with leaky pipes, just open the main, grab your tools, and start fixing wherever water is leaking". So we did it, we launched drummy earlier this week on /r/InternetIsBeautiful and we got very close to 10k users in just one day! Survived the hug of death, learned a ton, and made changes all around.…

I'd like to get some input on my project from the Hacker News community. The Reddit thread can be found here: http://www.reddit.com/r/reddit.com/comments/j5bl3/can_whoever_makes_browsers_please_consider_adding/ The extension itself is located here: http://www.mutetab.com/ Basically, my project is a Chrome extension that attempts to provide browser-wide sound management to the extent possible within an extension. It helps a user find what is making sound by identifying what is possibly making sound, allows automatically muting background sounds, and provides a context menu with sound…

Hey all. For the last few years, I have been developing a software synthesizer as a side project. It's taken longer than I both hoped and feared, but earlier this week I finally shipped 1.0. Details about the synth itself are up on my website, https://lhiaudio.com/. For those who are unfamiliar, in music production, there are host applications (such as Logic Pro, Ableton Live, or REAPER) in which most of the work (such as recording or sequencing MIDI data) is done. These applications generally have some built-in tools for the actual generation and processing of audio data, but…

Hey HN, I built a website where you can train Llama 3.1 8b & 70b (4bit) on your data. I use unsloth in the backend and the training is done on H100s which I rent programmatically from Runpod. I'd love some feedback. If you would be interested in using it feel free to book a chat with me: cal.com/hamada/tunellama-intro Happy to give you free credits :) P.S. I'm also looking for a co-founder as I have big plans for this.

Just wanted to make my first post about something interesting I've been working on for some time. Any ideas/suggestions for new hardware or software I should try out are welcome, though I will only have time for a major overhaul in a month or two where I want to redo and document everything a bit better than how it is currently. Hope this can inspire someone to start their own homelab or give some ideas to already existing ones!

Learn how to write Rules Engines with CLIPS in your browser! I found the Tour of Go super useful when learning Go, so I went for something similar for evangelizing the awesomeness of CLIPS. A few things I'm proud of with this project: - No front-end frameworks - Compiled WASM binary; your code isn't sent to a back-end server - Code editor/syntax highlighter written from scratch (that I'm sure you'll find bugs in ;)) This is my first attempt at this, and I'd like to expand on it in the future. Let me know what you think! About CLIPS: CLIPS is a programming language useful for building…

I went nuts on Sunday after stumbling on this animator script for the automatic branch: https://github.com/Animator-Anon/Animator And then it's a ton of keyframing. I also found that the timings all have to be earlier than the timestamp you want to account for how long it takes to denoise to your new scene - so like .4 gives smoother but longer, .7 is snappy. To get stuff to keep showing up and stay dynamic you can zoom out continuously, it needs a UI, badly. If you're on windows you'll need ffmpeg too. I watched this when it came out last week:…

Hey HN! I built Transcrib.ee to help me generate transcripts for lectures on YouTube with no captions, especially multilingual lectures. I was constantly frustrated with videos that had no transcripts or inaccurate ones, so I built a tool and decided to share it with everyone. This tool uses Groq (an AI inference engine that's different from Grok and offers very fast processing) and OpenAI's Whisper model (really accurate in multilingual) to quickly transcribe any YouTube video, regardless of the language. It's been a game-changer for my studies! To make it even faster, I created a Chrome…

Hi - I'm part composer, part engineer and big fan of reading blogs where people learn out loud or with the garage door up by sharing their notebooks or journals. I've been doing this in Moleskines for years (going back to the 80s) but made it a new year's in 2024 resolution to post SOMETHING everyday, so long as I created the sound. I have a big archive of demos and seeds of ideas, so I figured it wouldn't hurt to do something with those in the process. Being so steeped in programming for the last 30 years, a healty chunk of this material is made via coding with Csound, TidalCycles, some raw…
