I've been working on a non-audio related project in an attempt to grow a small non-profit I'm part of. The head of the organization found some potential donors who are "model train enthusiasts" hoping to modernize their setup. I personally don't give a shit about model trains, but it's been an interesting technical project. Thanks to some very committed people in that community, there are some awesome free open source tools that are pretty impressively developed. I've got an arduino with some accessories doing the heavy lifting, and a PC running bitfocus companion which fucking rulez.
My day job is AV support at a college. Bitfocus companion is basically a free open-source version of control systems like Extron, and it's built to use off the shelf elgato Stream Decks (and some similar devices) as control surfaces. So basically I'm using my AV control programming experience to program this in much the same way. There's a lot of developed modules for video stuff, but there's also a fair amount of audio stuff as well. Allen & Heath, Behringer/Midas, DANTE, Digico, SHURE, and Yamaha RCp all stood out as I scrolled through. Anyway, if you're into that sort of thing, and you've got gear with some kind of control protocol, this seems like it could be great for tying things together and doing some pretty advanced control. Or if you're a camgirl and you want to run your setup from a streamdeck, you can do that too.
