Nowadays ossia is more about the content creation part, with a whole graphics pipeline amenable to VJ and real-time audioreactive visuals, where you can for instance have AI models like streamdiffusion & the like (https://streamable.com/zfrbo3) or just play with VST plug-ins and drum machines to make beats (https://streamable.com/fc02so)
All the recent artworks I've worked on involving ossia have used it exclusively, for instance for light, sound and video design, while if I'm not mistaken Chataigne is more commonly used in conjunction with for instance software such as Live or TouchDesigner.
It's very good for video mapping but for instance wouldn't allow you to do any kind of remotely advanced audio effects such as loading a VST to apply to your sound or play MIDI instruments. From the docs it only supports Mono, stereo, 5.1 or 7.1. ; in contrast ossia has been used to drive multiple many-channel spatialized sound artworks. You can trivially use the library of Faust spatialisation tools for instance to do ambisonics, VBAP etc. with either graphical utilities or through generative means with some simple scripting.
I'm not sure Millumin's timeline allows to do something like this either which has multiple kinds of interactions deisgned in a visual language, or state-machine-like behaviours: https://ossia.io/assets/feature-interaction.gif

Plus a variety of Video DJ platforms like VDMX, Arkaos, GrandVJ, which have some of this functionality, and then a lot of free and commercial DMX-512 lighting control software and hardware that can be interfaced to these show control systems. Q-Lab is widely used in the stage show industry. Chataigne is one I hadn't heard of.
Never actually heard of v-control , it's website is rather light on details.
Isadora and TouchDesigner are very much in the same vain as Ossia
1) ossia score 3.5.3 was released :)
2) We're going to give a lab on interactive graphics on embedded platforms at SIGGRAPH in Vancouver in August, which teaches how to do real-time visuals with interaction on Raspberry Pi:

3) The Ars Electronica prize results were announced today and two works using ossia-max, our Max/MSP binding, got featured at Ars Electronica 2025:
- Organism + Excitable Chaos by Navid Navab and Garnet Willis got the Digital Musics & Sound Art Golden Nica
https://calls.ars.electronica.art/2025/prix/winners/16969/
- On Air by Peter van Haaften, Michael Montanaro and Garnet Willis got a Digital Musics & Sound Art honorary mention

Earlier this year, ossia was also featured at the Venice Biennale, it has been used for the Pavillon of Ireland: https://www.innosonix.de/pavilion-of-ireland-at-the-venice-b...

The whole Who Wants To Be a Millionaire sequence comes to mind (where, on an arbitrarily timed cue, the lights physically rotate downwards, synchronized with the electronic score and floor panel animations, to bring pressure onto the contestant). And from a bit of research, they needed to do a fair amount of work for that, which arguably could have been "orchestrated" from software like this: https://www.tpimeamagazine.com/robe-rig-lights-who-wants-to-...
> Synching the lighting consoles to receive MIDI triggers from the show’s gaming computer which activates specific commands for sound and video related to screen content was an intense talk that took plenty of work and lateral thinking. Additionally, more signals from the lighting console were used to access the media server operating a series of pixel SMD effects inbuilt in the set – so there was a lot of synching happening!
I'm also aware of software like https://lightkeyapp.com/en - but ossia score seems to focus more on temporal flexibility/coding/behavior as the primary focus, whereas Lightkey focuses on the physical layout of lighting at any given time. Arguably the feature sets should merge - Blender's ability to have multiple views that emphasize or de-emphasize the timeline comes to mind!
These things shouldn't be blocked behind massive investments. Anyone who can put a few cheap tablets on stands and plug in a MIDI keyboard should have best-in-class visualization capabilities, and be able to iterate on that work as more professional hardware becomes available. It's one of the things I love about open source.

Judging by the Robe press release there's a good chance the lighting was controlled by an Avolites console which is owned by Robe, Avolites' desks also have the ability to control video.
Lightkey is more hobbyist level control software, its a very visual application. If you want to see the more professional stuff look up MA Lighting's GrandMA2/3 consoles, Avolites Titan software or ETC's (Electronic Theatre Controls) Eos. The software is more akin to a glorified spreadsheet/command line interface then a nice and approachable interface like Lightkey
