Remote Piano

A toy piano app made with Flutter as a gRPC example, with a unique feature to interact with remote devices.

Supported platforms

• Android
• iOS
• Web (limited)
  • gRPC-Web is used for web instead of grpc-dart.
  • Sending notes is not supported due to the limited functionality of gRPC-Web.
  • Receiving notes does not start unless you send a request by tapping a key after connected to a server.
  • Tapping more keys cause an error printed in a browser console.
  • A gateway proxy is necessary between a server and clients. See below for instruction.
    • See the README of piano_server for details.

flutter_midi and Tone.js are used for mobile and web respectively.

No sound font (.sf2) file is in this repository.
Search and get one, place it in /assets/sf2/, and then specify the file path in pubspec.yaml.

Server

A server is necessary if you use the remote operation feature of the app.
Its source code is on another repository.
