Lots more wiring - worrying about ground loops and overloaded 5 volt circuitry. Then, vocal gymnastics and a discovery - capacitors where they shouldn't be.

    Glad it was only on two bars. It was a great example of what NOT to do. Still, a bitch to fix, huh? Other than that "offset", well done. 🚦 🚦

    That is so cool. I agree that a signal generator would be more "exacting". I have no problem with your oral inputs, but… 🙂

    Just a thought! Would it be possible to have something like a MSGEQ7 (Spectrum Analyser) and have that control the Teensy 3.2 + Audio board using the Lo Pass/Hi Pass filter to get a vocoder effect? …guess I should just try it myself!

    It looks like the leads to your VU's are just in sockets, cant you just cross the feed wires over lol then you wont have to desolder anything 😀
