Hi, Patrick here! I was the original author of Waltz during my time with WorldStage. This is an archive of the content originally available at and It is archived here as WorldStage has announced they are ceasing operations, and this information may be of historical interest. Download links throughout are most likely broken and many other links may also be broken. I'm working on providing an archive of the publicly available builds of Waltz I am aware of and downloaded over the years, but without a license key many of they are probably not of very much use to most folks anyways. None the less, it is important to me to document as much of this as possible lest it all be lost to the sands of time.

IMPORTANT: Please read our statement regarding support starting March 23, 2020 and effective until further notice.

Welcome to Waltz, WorldStage's node-based flexible show control platform for lighting, video, and more.
