Experiment in trying to play real-time music with someone over the network.
What is done
- Browser getting midi signal from the instrument
- Playing the midi notes locally via a simple oscilliator
- Establishing a RTC connection between 2 browsers
- Playing notes over the peer-to-peer connection into the other browser's oscilliator
What is not done
- Handling more than 2 person at the time
- Deconnections / Re-connections
- Optimizing events and data for faster transfer and decoding
- Setting up the signaling server and website on a publicly reacheable place
- Choosing midi output
- This hasn't been tested in a browser other than chrome 85
How to run
- install npm dependencies
docker-compose run npm install - run the web server and the websocket server
docker-compose up -d - open 2 browser tabs in the same console, and verify that you get the
Channel opened!message - Chrome asks for a user interaction before it allows to play sounds. Make sure to click the "Enable Audio" button to hear the synth.
To run on a network
- Change the websocket server address in
www/js/signaling.js - In chrome, midi is blocked by default on websites that don't have an https connection. You can workaround this using the flag
chrome://flags/#unsafely-treat-insecure-origin-as-secure.
The local midi+oscilliator part can be tried online here (no RTC setup yet). https://tabarnotte.com
