Things people build with this

USE CASE 1

Script a complete drum, bass, and hi-hat arrangement in Python and export it as a WAV file without ever using Bitwig's mouse interface.

USE CASE 2

Automate repetitive Bitwig tasks like setting up sidechains and loading effects across multiple tracks from a Python script.

USE CASE 3

Generate algorithmic or procedural music arrangements directly inside Bitwig Studio by writing code instead of drawing clips manually.

Getting it running

Difficulty · hard Time to first run · 1h+

Windows only, targets Bitwig Studio 6.0.6, requires installing a bridge component into Bitwig's user directory and enabling it inside Bitwig's settings.

Free to use and modify, but any software you distribute that includes this library must also be released under the GPL-3.0 license.

In plain English

openwig is a Python library that lets you control Bitwig Studio, a music production application, by writing code instead of using the mouse. You describe a song in a Python script: the tempo, number of bars, which tracks to create, which instruments and effects to load, what notes to play, and any automation such as volume changes over time. The library then connects to the running Bitwig application, builds the arrangement inside it, and renders the result to a WAV audio file. The library goes further than what Bitwig's built-in controller scripting supports. The official API is designed for hardware controllers, but openwig creates and arranges tracks, loads devices, sets up sidechains, and writes automation directly inside the app. The code example in the README creates a four-bar song with a kick drum, a bass line with a filter effect and volume ducking, and hi-hats, then exports the result as a WAV file in roughly fifteen lines of Python. The project is in early alpha and runs on Windows only, targeting Bitwig Studio version 6.0.6. Installation involves installing the Python package, running a setup command that copies a bridge component into Bitwig's user directory, and then enabling the bridge controller once inside Bitwig's settings. A doctor command can verify the connection is working before you start composing. The source code is released under the GPL-3.0 license. A documentation site covers installation steps, troubleshooting, and uninstalling. The repository accepts bug reports and contributions through GitHub issues and discussions.

Copy-paste prompts

Prompt 1

I installed openwig and enabled the bridge in Bitwig Studio 6 on Windows. Write me a Python script that creates a four-bar beat with a kick, bass, and hi-hats and exports it as a WAV file.

Prompt 2

Using the openwig library, how do I set up a volume-ducking sidechain so the bass track dips every time the kick drum plays?

Prompt 3

I want to add a melody track with a specific synth preset loaded in Bitwig using openwig. Show me the Python code to create the track, load a device by name, and write MIDI notes.
