Thanks for this thread, and thanks for the videos showing how you actually created the patches. I just bought a used HD500 (not the X) to get me by until I can afford the X or better, and I'm still getting to I know the board. I find seeing how you created them extremely helpful. Also, it has at least one foot switch that will need to be replaced, so I'll definitely be digging into that video later this evening.
Have you ever replaced the toe switch on the pedal? This one seems to be non-functional. Is it the same type of switch?
