   What if your synthesizer was powered by APL (or a dumb K clone)?▲92

   I built k-synth as an experiment to see if a minimalist, K-inspired array language could make sketching waveforms faster and more intuitive than traditional code. I’ve put together a web-based toolkit so you can try the syntax directly in the browser without having to touch a compiler: Live Toolkit: https://octetta.github.io/k-synth/ If you visit the page, here is a quick path to an audio payoff: - Click "patches" and choose dm-bell.ks. - Click "run"—the notebook area will update. Click the waveform to hear the result. - Click the "->0" button below the waveform to copy…

   I used AI to recreate a $4000 piece of audio hardware as a plugin▲160

   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…

   I built a WebMIDI sequencer to control my hardware synths▲43

   Hey HN, I’m an ex-Google engineer trying to get back into music production. I needed a way to sequence my hardware synths using AI contexts without constantly switching windows, so I built this. It runs entirely in the browser using WebMIDI. No login required. It connects to your local MIDI devices (if you're on Chrome/Edge) and lets you generate patterns. Tech stack: [React / WebMIDI API / etc]. Link: www.simplychris.ai/droplets Code is a bit messy, but it works. Feedback welcome.

   I built a handheld CHIP-8 game console to teach myself embedded systems▲128

   A while back I wrote a CHIP-8 emulator (which is considered the Hello, World! of emulators and is more accurately a virtual machine since historically CHIP-8 was an interpreted language running on top of the COSMAC VIP to make game programming easier). But a few months ago I got really interested in embedded software, so decided it would be neat to port my emulator to a STM32 MCU and design a console around it as a learning experience, since CHIP-8 never existed as a physical system. I didn't know much about embedded software when I began, and even less about electronics, but I managed to…

    A 16-control subtractive synth for microcontrollers (39k ELF, web demo)▲6

    This toy retro synth installs and runs on esp32-s3 or p4 as an ELF file under BreezyBox firmware. It uses my work-in-progress immediate mode TUI library in C. Web-based version via emscripten: https://mini000.itch.io/beeper Source code: https://github.com/valdanylchuk/beeper Demo video running on Tanmatsu (esp32-p4): https://www.youtube.com/watch?v=uCH9XYZ7QB0 The main challenge I was going for was actually to find a nice minimal set of controls for a subtractive synth. Usually there are 40-50 of them in "simple" synths; I ended up with 16.…

    I just released my first commercial audio plugin▲7

    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…

    Anyma V, a hybrid physical modelling virtual instrument▲79

    Hi HN! We're a small team in Lille (France) who make synthesizers and MIDI controllers. We've just released a virtual plugin version of our hardware synth Anyma Phi, which offers a semi-modular environment with a focus on physical models, although there are several other kinds of synthesis. Here's a video: https://www.youtube.com/watch?v=6efDQ9GmRpg We're not pivoting to VSTs, it's just that it was a practical way of investigating several issues and helping us with the ongoing development of our upcoming Kickstarter-backed synth (Anyma Omega) and MPE controller (Loom), and a…
