Question I followed the instructions and connected the pedal to a DC supply, connected the USB cable from the computer to the pedal and then tried running the TonePrint Editor. The pedal was not recognized  (even if I logged in as administrator) and the Editor only showed a grey background. Leaving it running for a few minutes did not solve the issue. What is wrong Answer The way to get around this issue is simply to reconnect the pedal to the computer via USB or to turn the pedal off and on again.
