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 curves, and full multi-track songs from a Python program. Render to .wav, export to MIDI/JSON.

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

from openwig import Song

s = Song(tempo=128, bars=16, clean=True)

kick = s.track("KICK", device="v9 Kick")
kick.fx("Saturator", Drive=0.20)
kick.clip(s.pulse(36, step=1.0))

bass = s.track("BASS", device="FM-4")
bass.fx("Filter")
bass.clip(s.pulse(33, step=1.0, off=0.5, dur=0.4, vel=0.85))
bass.pump(hi=0.82)

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 git+https://github.com/Axyom/openwig.git
python -m openwig install   # copies the controller into Bitwig's user dir
python -m openwig doctor    # verify deps + controller + bridge

Then in Bitwig: Settings → Controllers → Add → OpenwigBridge (one time).

Contributing

Issues and PRs welcome. Currently Windows + Bitwig 6.0.6 only.
