Web Serial needs Chrome, Edge or Opera over HTTPS. The port is chosen by you, per session.

Demo device

Pretend to be

A simulated device on the other end of the console, for trying the decoders and the sender out without hardware — and for browsers with no Web Serial at all.

MIDIterm bridge

Send DIN MIDI to MIDIterm Take MIDI from MIDIterm

DIN MIDI on a UART is still MIDI once something puts it on a port, and MIDIterm is that something. Open it in another window and the bytes off this port play out of a real MIDI output — and what MIDIterm hears comes back down the wire. It never leaves the browser.

Decoding
