I'm trying to create an instrument using my game controller, and i have a simple problem. I need the buttons to switch things on and off when i press them, but of course it sends one signal when pressed and another when released. I know there's a way around this, but I'm quite new to PD and I don't know how. If someone could help I'd really appreciate it. Thanks!

thanks for all your help guys! i'll try these things out. and yeah, nestor, i'd love to take a look at yours. i do want to build my own, but i could learn alot by looking at others.
