When I press a single button on my controller I get either notes 2,4,6,8 or 1,3,5,7 all outputted at once?! I have 7 buttons and one accelerometer I'm using as a pot. I do have all the button grounds connected together to a single ground on the controller.. is that why its freaking out? Ive even tried to put a diode on the neg side of 3 buttons to try and isolate but no change. Whats going on??

Im designing a wearable. So the less wires the better.
So the BC1 and BC2 are a common ground for 8 button groups? I'm using 7 buttons, so I only need one wire from each button to BR1-7 and a ground on BC2?
OH never mind, I had it backwards. On the advanced digital Input File:AdvancedButtonHeader.jpg the positive side #2 can be a common ground for buttons 1-8 on the neg side!
