Did you know that rubber cement is the least useful adhesive known to man? The only thing going for it is easy removal. Really, far too easy removal.
So! I made two improvements to my DIY Live footswitch.
First I pulled out the white springy parts on the surrounding keys so you don’t accidentally hit space when you’re trying to hit B. (In case you’re not a Live user, space is the default key to stop all audio.)
Second I gave up on gluing the discs to the keys and elected to screw them on instead. Drilling a hole in something as small as a computer key is a bit tricky, but it’s nothing a pair of vise grips can’t handle.
Now the footswitches don’t slip off all the time. Truly, this dismal hack is road worthy.
