2AP
A platform for remote piano lessons based on the Web MIDI API▲224
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!

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.

Pixeltune, a nicer chiptune and VGM player▲80
10 years ago I began working on Muki, a web-based MIDI and chiptune player which I eventually announced here on HN[0]. It was a fun weekend project. Over the years I received numerous requests from people that wanted more: more music, more features, more playable formats, you name it. Eventually I began working on a complete rewrite of the app (this time for real), and, realizing that each year another chiptune or MIDI website went offline, I decided to start archiving them for preservation. Today, 10 years after the first release, I think it's finally time for the new, nicer version to hit…
