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.
