Show HN: I built a WebMIDI sequencer to control my hardware synths
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].

Code is a bit messy, but it works. Feedback welcome.
