SUSHI GUI

A generic GUI for controlling Sushi over gRPC, built with Python and QT. It can control both local instances and remote devices. Intended for testing and development.

Installation

It is assumed you have Python 3 on your system. And Sushi, of course...

After cloning this repo, do not forget to run git submodule update --init --recursive!

Dependencies

The preferred way to install deps is in a virtual environment. Here is how to do it with the builtin venv module. Using virtualenv instead is also possible.

python3 -m venv venv will create a virtual environment named venv with your installed Python
source venv/bin/activate to activate that environment
pip install -r requirements.txt to install all the dependencies in the environment

Sushi .proto definitions

sushi-grpc-api is included in this repo as a submodule. It contains the proto definition file for Sushi. In the Sushi repo, you will find the .proto definition file for Sushi. By default, this GUI will use that.

In case you need to use another proto file, you should set the environment variable SUSHI_GRPC_ELKPY_PROTO to that path.

Also, note that Sushi comes with its proto file when you check it out. Specifically in sushi/rpc_interface/protos/sushi_rpc.proto. So setting environment variable like that:

$ export SUSHI_GRPC_ELKPY_PROTO=path_to_sushi/rpc_interface/protos/sushi_rpc.proto

will make the GUI use the proto file included with Sushi.

If you find yourself using this often and wanting to set the variable once and for all, you should add the command to your .bashrc or .zshrc, depending on which shell you are using.

Usage

Assuming that Sushi is running on your machine:

$ python3 ./sushi-gui.py

Controlling Sushi when it is running on another machine

The GUI lets you specify an IP address and port number to connect to. Simple as that.

In case you need to hard-code a different default address than localhost:51051, feel free to edit sushi-gui.py:4:

SUSHI_ADDRESS = 'localhost:51051'

with the new default address.

Limitations

Although meant as a debugging/testing tools for Sushi developers, this GUI does not implement all of Sushi's features. Most notably, some behavior one might expect after learning about the notification system is missing:

Processor update notifications and ordering

Sushi allows for adding processor anywhere in the processor stack. But this GUI does not. When adding a plugin, it will always add it at the bottom of the stack, i.e. in the last position in the audio flow. This limitation gets even more annoying when the processor addition is done via other means which do allow for insertion in any position because this GUI will not reflect the new ordering: the new plugin will always be shown at the bottom of the stack even though it is actually somewhere else. Keep that in mind.
