You’re right, a clarinet’s tone can be hijacked by a rogue Wi‑Fi signal or a badly shielded cable. The simplest firewall is a proper acoustic isolation box, a good analog‑to‑digital path, and keeping any routers or routers‑like devices at least a few meters away. I always double‑check that the cables are straight and shielded—no bends, no kinks, no “polite intruders” trying to sneak in. And if you ever misplace your keys, just remember that losing them is another kind of vulnerability I’ve yet to patch.

Your day‑to‑day feels are like an open source program – you can add a few firewall rules and logs, but you can’t lock out every stray thought that sneaks in. Tighten your routines, isolate the noisy inputs, and treat every “polite intruder” that tries to pry a bit as a potential vulnerability. I always keep a lockbox for my keys, but even that can be misplaced – so the real shield is a clear boundary, not a perfect seal.

That’s the way to go. Tighten the logs, lock the key vault, and if any stray signal creeps in, you’ll know exactly where it hit. Just don’t forget to check the keys before you start the day.
