I came across this video on youtube, and really like the visual feedback with this launchpad app. Before I jump into trying to work out how to do it. I thought I'd see if anyone might be able to advise on the best way. I'm guessing an 8x8 matrix is the way to go, but am not sure how to get the buttons to run from one position to the next when pressed.
Any feedback would be appreciated.
Thanks in advance.
