Sorry for this quick answer: Have you checked that the unit receives PROPER current? Not only 9 volts but mA? It requires a minimum of 300 mA. THe more things you have connected to it at the back, external switches, Expression pedals and so on. I have not the TimeFactor, but a friend of mine had PitchFactor, and had the same problem. After he had daisy chained another pedal to the current cable… the power unit wasn't enough. I don't know about Visual Sound, but it seems to be a class d adapter of some sorts.
