It reminds me of wind instruments with the same fingerings, and how you think you can go from one to the other and just blow, but then it turns out, nope. I could just imagine a saxophonist picking up a flute and being like, "This thing doesn't work right. And, the sound is way off."
For anybody interested, you can find some presets to work with, here:
