I wish that someone would make this, but they can't.

A thing that looks like a 3.5mm dummy plug.
Each one has some LED indicators, and each has a unique ID.
They act like cordless patch cords. Bidirectionaly, electrically transperent.
~5 meter range. Long battery life. Maybe parasitic power?
A local (not cloud) little box configures the plugs, talks to an app,
and also acts as a charging and enrollment station.

One-to-one and one-to-many connections.
Each has an amplitude and offset, perhaps some modulation.
Named groups and load/save of presets.

$240 for the starter box, $17 each for plugs.
Just plug 'em in. Everything but with no wires in the way.

Of course they'll never/can't be made, but wouldn't they be fun?

Sounds like battery powered hell, I think VCV rack would be better! ;-)
Though I guess a Bluetooth Rack-Plumber would be a good idea if the price poit could be as with a Plumb Audio Rack Plumber.

We can simulate a thing with VCV on a computer, but it can never really be that thing.
I know this is only a thought exercise. Just doing MIDI like this would be tough. (or does that exist?)
Bluetooth would suck for this. No Bluetooth, too slow. Maybe an RF/optical hybrid?
To simplify it, two kinds of plugs input and output.
Forgetting miniturization, what does it take to transmit and recieve a 0-10v 0-20Khz DC
signal wirelessly and accuratly, with minimal lag?

Could an electrical engineer come here and teach me about how wrong/impossible this is and why?
Can we get close?
Because the world is waiting for a $250 replacement for an $8 patch cord. :)

Interesting idea, make it happen, lol!
