I recently procured a musical keyboard, with a pedal that attaches to the keyboard via a wire. It looks like this:
The problem is, it runs away every time I try to play the keyboard. I step on it, and it moves farther away. I raise my foot, put it down again, and it scoots farther away.
How do I make sure that this doesn't happen, without putting something behind it that will mess up the cord?
