The LightjamsPAD is a general purpose OSC controller, optimized for touchscreens. It sends to Lightjams the pressed state of each button and Lightjams sends back the RGB highlight color of each button.
You can run the LightjamsPAD on the same computer as Lightjams or, since it's using the OSC protocol, you can put it on another computer/tablet on the network. You can even use multiple LightjamsPAD at the same time and their states will stay in sync!
I've attached a sample project file showing how to create various types of controls: toggle buttons, group of buttons, instant...
On a real project, you'll replace the LightjamsPAD intensity attributes by your grid/group activation attributes and move the PAD intensity attributes into the proper grids.
