I have the Spider valve 112MKii combo and the Express pedal. I have had a hell of a time figuring how to set up this stuff. anyhow, the express pedal works fine,(stores only 4 sounds/wah and volume) but when I hook it up to my computer, it goes blank.(the pedal) I have all of the drivers installed, and collaborated the pedal, I just want to get MKii EDIT to work, but the computer does not recognize the amp because the fbv express turns off when I plug in the USB cable from the pedal to the usb port on the computer. can I bypass this and use MKii EDIT directly somehow? any ideas??
