Paul Hammant found this cool Server-Side Piano and I’ve modified it to be configurable from a running App-Config-App. Because the sound is generated at the server, you’re able to see (hear) the Server-Side Piano change its configuration without reloading the UI.
Making it work for yourself
I’ve updated the App-Config-App with additional configuration to support choosing which instrument the Server-Side Piano will play. A clean install of App-Config-App using
setup_examples.rb will provide everything needed to run the Server-Side Piano.
The application’s configuration URL and credentials are located in
web.xml. Additional details may be found in the application’s README.
