How do I determine the scan matrix of my piano keyboard? Answered
I am trying to convert my old shitty keyboard into a midi controller by following the instructable by Evan Kale;
but when connecting two wires of the ribbon to my multimeter, which is set to continuity mode (as seen at 1:30 of the video in link above), there is no response from the multimeter when pressing the keys in order to determine the scan matrix.
Am I doing something wrong?
