I have been using the stomp to send midi messages to a laptop to trigger sound effects and audio clips. During my bands practice last night it just stopped working. I have verified with two different laptops and multiple software that the stomp is no longer sending midi over usb. I have triple checked the config parameters and everything is as it should be, I have replaced the cable, and I even tried a factory reset. Does anyone have any other trouble shooting ideas? I am at a loss. It worked fine one song and nothing the next.
