Show HN: Automate your studio – mute a mixer channel to turn your PTZ camera

The amount of neat things my synth friends do, including controlling lighting, with control voltage has me dreaming of a world where knobs and levers and UIs generally were way more customizable than we have now.

&gt; We needed to move a PTZ cam based on the stage&#x2F;pulpit mute states on our X32, but it is capable for way more.<p>PTZ - pan&#x2F;tilt&#x2F;zoom camera, that much I understood. The rest? Uh… can I get an ELI5 please?<p>Even though I’m clearly not in the target demographic, I’m eager to learn more..<p>Edit: ok, clicked through to GitHub, now I (kinda) got what it’s for :)

Starred!<p>I’ve been playing with hooking up a MIDI controller to my OBSBot Tail Air PTZ camera and OBS.<p>The config and filters and triggers looks similar to my prototypes.<p>I’ve been wondering if there’s any sort of prior art or standards here from other domains like lighting consoles or workflow systems.

I&#x27;m curious, did you ever come across Chataigne?<p><a href="https:&#x2F;&#x2F;github.com&#x2F;benkuper&#x2F;Chataigne">https:&#x2F;&#x2F;github.com&#x2F;benkuper&#x2F;Chataigne</a>

I did an explainer on OSC to explain the concepts. Indeed I think its the easiest network protocol to just hook different things together: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=0uOR2idKvrM" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=0uOR2idKvrM</a>

Could you have some sort of tee, so instead of dedicating a channel you multiplexed a second extra-audible signal (outside the audible range) onto the same channel? Or perhaps send a really low frequency signal over the cable sheath??<p>Just spitballing.

Is there a reason to use this over Bitfocus Companion?

Very nice! The ability to get novel interactions out of connected devices is something I think we&#x27;re just starting to bloom.

Unrelated, I have an old Axiom midi controller that I&#x27;d like to reprogram to use with GarageBand. I&#x27;m not sure where to start, but I&#x27;m thinking of using Go or Rust. Do you have any pointers on how to get started?

OSC (Open Sound Control) is just awesome. It&#x27;s basically a lightweight protocol on top of UDP packets. It&#x27;s not hard to roll your own implementation if there isn&#x27;t one for your platform. It&#x27;s lacking a lot of features you&#x27;d need for a scalable system, but when you just need a few systems to send realtime messages to each other, it&#x27;s tough to beat.<p>I&#x27;ve used it a lot for the original designed use-case (sending parameter updates between controllers and music synths), but also a bunch of other things (sending tracking information from a python computer vision script to a Unity scene).
