How to simulate Keyboard In CHOP with Audio Device In

Hi, I’m really new to TouchDesigner and I’m currently trying to make a randomly generated image that is triggered by a seed that randomizes with every Keyboard In signal. I wanted to take it a step further by using an Audio Device In (guitar) that has been filtered up until it gives a trigger either 1 or 0. But whenever I tried to connect the trigger to the seed generator the image won’t render and it gives an error message “unsupported operand type”
