openwig

Algorithmic composition for Bitwig Studio. Write Python, get songs.

Goes where Bitwig's official Controller API can't: build arrangements, devices, modulators, sidechains, automation, and full multi-track songs from a Python program, then render to .wav.

Free and open source (GPL-3.0). Windows only. Early beta.

A Note is (key, start_beat, duration, velocity) with named fields and defaults - build them with ordinary Python. openwig stays a thin layer over Bitwig; bring your own patterns.

from openwig import Song, Note

s = Song(tempo=128, bars=4, clean=True)

kick = s.track("KICK", device="v9 Kick")
kick.fx("Saturator", Drive=0.20)
kick.clip([Note(36, beat, dur=0.25) for beat in range(16)])             # four-on-the-floor

bass = s.track("BASS", device="FM-4")
bass.fx("Filter")
bass.clip([Note(33, beat + 0.5, dur=0.4, vel=0.85) for beat in range(16)])  # offbeat root

s.master(["EQ+", "Compressor+", "Peak Limiter"])
s.play()
print(s.render("song.wav"))

Compatibility

openwig	Bitwig Studio	Python	OS
0.1.x	6.0.6	3.11+	Windows

The SDK reaches into Bitwig internals that move across releases, so it targets a specific Bitwig version. A mismatch refuses to connect with a clear error- bump the SDK when you bump Bitwig. Rendering uses WASAPI loopback (Windows).

Install

pip install openwig
python -m openwig install   # copies the controller into Bitwig's user dir

Then in Bitwig: Settings → Controllers → Add → OpenwigBridge (one time), and verify with python -m openwig doctor.
