I can’t teleport with the whammy bar, how do I fix this?

When the game boots, it sets the current whammy bar position as the default position. Because of this, a pressed whammy bar can make the game unable to register a motion later. The easiest way to solve it is to close the game and re-open it, or un-pair your guitar controller and pair it again, being careful to not touch the whammy bar during the process.
