Most ribbon controllers are linear, but the one on the Otamatone behaves like a guitar or a cheap theremin, with higher notes closer together. Can it be made linear?

  • Hi Mark. Can you clarify what you are asking. You have 2 questions here. – Doktor Mayhem Apr 24 '16 at 16:29
  • Ribbon controllers are basically unrolled potentiometers and, as far as I know, a "Linear Pot" can be converted to a logarithmic one by adding a resistor. Presumably the opposite can also be achieved. – Yorik Apr 26 '16 at 19:02

To quote Wikipedia,

The ribbon controller is deliberately delinearized to resemble a guitar, so there is a shorter distance between higher notes than between lower ones. - https://en.wikipedia.org/wiki/Otamatone

Basically, they're doing it on purpose because it's how most intonation-based instruments behave. You'll notice that people who play string instruments may be better at playing the, uh, whatever the Otamatone is. I don't really want to call it an instrument, but in light of evidence, I must say that it is fairly capable. ;-)

  • Thank you for the reference, however, I added that to Wikipedia based on information elsewhere. – Mark Green Aug 15 '16 at 19:54
  • Aha! (That's fairly awkward...) Would it be too much to ask for you to post the original source just for reference? After all, that's the point of this site. – General Nuisance Aug 16 '16 at 2:37
