Libretto.fm▲125Hi HN, I’ve been working on Libretto, a browser-based tool for editing long-form spoken content (podcasts, interviews, talking-head videos). You can think of it as a simpler, more focused alternative to Descript, optimized for editing long recordings faster. The motivation was pretty simple: editing spoken recordings still feels harder than it should be, and a lot of newer tools seem focused on short-form or AI-generated content.

Hi HN, I'm Erwin. I built a small free open-source utility that bridges Bluetooth LE MIDI keyboards into the new Windows MIDI Services stack so any DAW or Web MIDI app can use them as if they were wired. I bought a Roland FP-90X piano partly because it had Bluetooth MIDI. On my Windows 11 PC, pairing succeeded, but my DAW couldn't see the keyboard, and notes I sent from the PC never made the piano sing. After a regrettable number of evenings, I'd separated this into three independent bugs stacked on top of each other. The first one is the famous one: Windows only natively exposes BLE-MIDI…

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.

If you already know what bytebeat is, you don't need an explanation. If not, check my project :) Here is how it looks: SELECT mono(output( arraySum(x -> 1 / 6 * running_envelope(30 * (1 + x / 6), time, 0.05 * x, 0.005, lfo(0, 0.25, sine_wave, time / 8), 0.1) * sine_wave(time * 80 * exp2(x / 3)), range(12)))) FROM table; To check how it sounds, find the examples in the repository https://github.com/ClickHouse/NoiSQL

I made a software library for displaying piano music 7 years back, and recently ported it to the web (which is now easier than even ever). It displays sheet music as you play, and let's you take snapshots of specific chords, then keeps a running list of chords as keyboard visuals (instead of just displaying sheet music). Just a simple tool for songwriting/ figuring out songs by ear, or just understanding music key theory (which I'm admittedly a still a beginner at).
