I think if you are getting a steady stream of "On/Off" it's probably a bounce problem, or a problem with the code in the arduino. Also, make sure the Keymux64 board is wired correctly to the hall sensor board. I think I looked into this in the past, and the Keymux64 board is expecting 64 inputs going to ground, with the ground contact on the Keymux 64 board, and the hall sensor array is a series of 32 inputs, and then the last two contacts are a ground, then a 5V+. So, the hall sensor array should go to the Keymux 64 board inputs, except for the ground, which should go to the Keymux 64 ground, and the 5V which should be coming from whatever is also powering your Keymux 64 board.
If that is all hooked up correctly, then your problem is the Arduino. What code do you have uploaded to the arduino? It would be helpful to have it in front of us so we can see if the problem may be coming from there.
