Hi again, I am having some difficulty with digital inputs and outputs. I am trying to code a 3X4 keypad by addressing each line of 3 in turn via three digital outputs and then checking each of the four for any digital input. What seems to be happening is that the digital inputs are permanently in an 'ON' state.
My declarations are as follows and I have also tried them without the Tilda :

and the decoding stage is here (it looks big but it is the same thing * 4):

I wonder if you can see anything that is not right? In Pd itself the digital inputs are all 'enabled' and the outputs are coming on in sequence.
Hopefully ...
