Iam working on a major lemur project for various effects and main controls in VJ software Resolume Arena. In this context, I have to make a kind of switch panel with four custom buttons. The buttons is for activating the different layers in Resolume. I use four layer, so four buttons. The problem is that I have to make it such that only one button can be on at a time. So lets say if layer one is activated, and I press the layer two button, the layer one button will go off. And furthermore you cant switch off a button by pressing it again, you have to press another button. And only one button can be on at the same time.
