       | This is really cool! Live music, game shows, holiday light
       | displays, and anything in between can hugely benefit from this
       | kind of tech.
       | 
       | 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.

       | I think this general class of software is called Show Control.
       | There are commercial and open source projects that also do it in
       | some form:
       | 
       | https://en.wikipedia.org/wiki/MIDI_Show_Control
       | 
       | https://v-control.com/
       | 
       | https://qlab.app/
       | 
       | https://troikatronix.com/
       | 
       | https://derivative.ca/
       | 
       | 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.
