Launchpad lights going crazy

October 4, 2012 | 12:33 am

I’ve built a patch that is designed to light up the button that’s just been pressed on the Launchpad as well as all of those before it. The idea being that if I want to choose a number between 1 and 64 I can get a visual readout on the Launchpad of just how big the number is.

The patch works when I hit just one button, but if I’m clumsy and hit a few (big hands, it happens) the launchpad lights up buttons that I didn’t tell it to.

I’m sure it’s just a rookie mistake, I’ve only been using Max a couple of weeks. Any help would be greatly appreciated!

I figured it out, I needed a gate that would stop new MIDI data entering the patch until it had finished executing. Here’s my patch for anyone else getting stuck in the same situation.
