diyelectromusicI've written up a summary of a conversation I've been having with someone trying to map out the keyboard matrix for a Casiotone CT-101.
I thought it might be useful to see the thought processes and theory as I've tried to suggest, remotely, things for them to try to get to the answer.
It's been surprisingly difficult to find information the CT-101 itself, but I've found details from several similar keyboards which has helped.
