TuneFlow is a next-gen DAW that aims to boost music making productivity through the power of AI. Unlike traditional DAWs, TuneFlow has a plugin system designed to facilitate music production in almost all areas, including but not limited to song writing, arrangement, automation, mixing, transcription...... You can easily write your own algorithms or integrate your AI models directly into the song-making process. tuneflow-py
is the Python SDK of TuneFlow plugins.
pip install tuneflow-py

The core idea of TuneFlow's plugin system is that you only care about the data model, NOT the implementation. A plugin's only goal is to modify the song, and the DAW will get the modified result and apply changes automatically. Below is an illustration:
A python plugin bundle consists of 2 components: The bundle file and the plugin files.
The bundle file, which we usually name it bundle.json
, contains the information of the plugins in this bundle. The information here will be shown to the users before they need to load the code of your plugin.
An example manifest file looks like this.
{
"plugins": [
......,
{
"providerId": "my-provider-id",
"providerDisplayName": "My Provider Name",
"pluginId": "my-plugin-id",
"pluginDisplayName": "My Plugin Name",
"version": "1.0.0",
"minRequiredDesktopVersion": "1.8.3",
"options": {
"allowReset": false
}
},
......
]
}
Under the plugin's root folder we need to create a plugin.py
file, which is where we define the plugin code. You can put other source code under the same folder, too. When TuneFlow runs the plugin, it adds the plugin's root folder to the PYTHONPATH
.
A barebone python plugin may look like this:
from tuneflow_py import TuneflowPlugin, Song, ParamDescriptor
class HelloWorld(TuneflowPlugin):
@staticmethod
def provider_id():
return "andantei"
@staticmethod
def plugin_id():
return "hello-world"
@staticmethod
def params(song: Song) -> dict[str, ParamDescriptor]:
return {}
@staticmethod
def run(song: Song, params: dict[str, Any]):
print("Hello World!")
Note: All methods here are static methods. This is by design: The entire plugin should be stateless -- the outcome of one plugin execution is only determined by the input and NOT by any internal states of the plugin itself.
When writing a plugin, our main focus is in params
and run
.
This is where you specify the input parameters you want from the user or from the DAW. It will be processed by the DAW and generate your plugin's UI widgets.
You can optionally use song
to get some additional information about the project's current snapshot, so that you can customize your params. For example, if you have a list of presets that applies to different time signatures, you can use init
to read the current song's time signature and filter out those options that don't work for the song.
Called by the DAW when the user actually runs the plugin by hitting the Apply` button.
Here is where you implement your main logic. The method takes in the current song snapshot (song: Song
), the params that are actually provided by the user or the DAW (params
).
To debug and run your plugin locally, you can use tuneflow-devkit-py
. For more documentation, visit: https://github.com/tuneflow/tuneflow-devkit-py
