openwig

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

Goes where Bitwig's official Controller API can't: build arrangements, devices, 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 alpha.

from openwig import Song, Note

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

kick = s.track("KICK", device="v9 Kick")
kick.clip([Note(36, beat, dur=0.25) for beat in range(16)])

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)])

duck = []
for beat in range(16):
    duck += [(beat, 0), (beat + 0.99, 1)]
bass.automate("volume", duck)

hats = s.track("HATS", device="v9 Hat Closed")
hats.clip([Note(42, beat + 0.5, dur=0.2, vel=0.6) for beat in range(16)])

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