Hello HN! This is a Python app I've built for fun, while learning the Textual library, it's a piano/synthesizer app that you can play with the keyboard + mouse. You can see a demo video of it here: https://www.youtube.com/watch?v=0VXit110PcA You need to install FluidSynth before using it: https://www.fluidsynth.org/ It uses the Python bindings pyFluidSynth library: https://github.com/nwhitehead/pyfluidsynth And the General User GS soundfont: http://www.schristiancollins.com/generaluser.php If you try it out, i'd love to…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

This is a keyboard in just intonation. It can play the notes a piano can. The big difference from a piano is that all the notes become consonant. At least, when you want to play a dissonant chord, you are clearly opting in to it because it's clear which notes are dissonant to each other. You won't bump into a dissonant note by mistake. You can play without knowing any music theory. Hit arbitrary notes with the rhythm you want, and the pitches will work. Not understanding the buttons is fine. Even rolling your elbow around your keyboard is fine. If you are a musician and press the wrong key…

Hey HN! A few years ago, I left my cushy big tech job to make hardware. And made the device I always wanted - an automatic piano recorder! I usually play piano improvisationally, and manually hitting record never meshed well with that. But there are always moments I wish I recorded, and now they are! Hopefully it scratches a similar itch for some of you as well! A few of the tech details: * built on an esp32-s3 * custom injection molded enclosure * BLE comms, sd card storage, DS1302 RTC * android & ios apps with Flutter * Shadertoy vfx support for video sharing - Chip

This is part of my journey on pybind11. I wrote a tiny FM Synthesis library in C++ and a Python wrapper for that using pybind11. There is a command-line piano app in the examples directory if you want to play with it. Here is the link: https://github.com/charstorm/koelsynth/tree/main/examples/si... My next target is to attach this to some kind of physics simulation - like a bunch of balls moving around in a box with some internal walls. When the ball hits certain trigger points, it produces the sound.

I always found sheet music way too hard to read - and I literally spent a year at a company building a sheet music rendering engine. I wanted an app that would display music like the tutorials on YouTube, but not be focused on upselling lessons etc. like most current apps, and also would let me import my own files This works on MIDI files. If it’s a valid midi it probably plays. Since releasing, I did add a subscription for classical music - on a theory that most normal users don’t know what a midi file is. It changed about a month ago from an up front price to in app purchases and/or a…

I 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.

I'm building a video conferencing app designed to facilitate better remote piano lessons. My hope is to solve a lot of the challenges piano tutors and new students deal with when taking lessons through Skype/Zoom. It leverages WebRTC's data transmission to send media, MIDI state, and (eventually) send sheet music files and other musical data. I'm surprised with how well the MVP has worked and would love to hear any feedback or suggestions!

A little weekend project, made so I can pause/play/rewind directly on the piano, when learning a song by ear.

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.

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…

Body: I built a polyphonic synthesizer in Python with a tkinter GUI styled after the Moog Subsequent 37. Features: 3 oscillators, Moog ladder filter (24dB/oct), dual ADSR envelopes, LFO, glide, noise generator, 4 multitimbral channels, 19 presets, rotary knob GUI, virtual keyboard with mouse + QWERTY input, and MIDI support. No external GUI frameworks — just tkinter, numpy, and sounddevice.
