Belt tension Y-axis - tightening causes it to change pitch
Your supposed to screw out one screw and then tighten the belt with another. Along with the sound app being quite useless although more functional on the y-axis, once you have found something that at least sounds like the strum from the video demonstration, when you then tighten the first screw it changes the pitch entirely, I can never get it correct no matter what I do once i secure it.
Also with the X-axis the mic is entirely useless, on a high end phone, it shows too high no matter if its too low or too high, and i strum quite gently or less gently. Its would be much better if they just uploaded a high end sound of how the pitch is supposed to sound, and go by that. I'm not entirely sure based on the audio from the video.
Meaning, I can never get the belt tension correct...
Wouldn't something like an item with a given weight and size, that you put on the top belt and when it touches the second belt its fine be much easier, or does that not work?
