creating an x/y controller for the launchpad

April 20, 2011 | 5:45 pm

Hi guys,

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 8×8 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.

Ok. So I’ve pretty much done it. As usual after wasting lots of time on more complex ways of doing it. I left it alone for a day and came back to it, and realized that there was a much simpler way of doing it. Just one small problem that I’m wondering if someone could advise me on.

When you go from top left to bottom right, or visa versa, it works perfectly, but when going from bottom left to top right, or visa versa, the x/y messages are reaching the matrix at different times, so the button doesn’t travel in a straight line.

Could someone advise on the best way to remedy this?
