As one of Vuo's developers, I work on Vuo's engine (the thing that makes compositions run), work on nodes, and write documentation. You'll see me on the forums answering people's questions about Vuo.
I enjoy using Vuo to make live music visuals. My hope for Vuo is that it will grow into a community of people of diverse backgrounds and identities making lots of different artistic, useful, unique, goofy, beautiful, crafty, wonderful compositions.
Estoy practicando para ser competente en español. Si publicas en el foro en español, trataré de responder en la misma manera.
The about menu and some other controls are localized in Arabic !
In System Preferences > Language & Region, is Arabic above English in your list of preferred languages? If so, then that is the expected behavior. Although Vuo itself doesn't provide an Arabic translation, these menu items and buttons are translated automatically by macOS.
If Arabic is not above English in your preferred languages, then this is a bug. If so, to help us troubleshoot, could you provide more info, such as a screenshot of your System Preferences > Language & Region settings (both General and Apps if on macOS 10.15 or later) and your macOS version?
There are a lot of missing standard nodes
That composition was created with a much older version of Vuo (looks like 2013-2014). To update the composition so it can be used with recent Vuo versions, you can open it in Vuo 0.9 and re-save it.
