I'm using VoiceTone C1 pedal for 6 months with no problem.
But today, while we were playing, it went wrong. Now, the C, C# and D scales are played a semitone up. It means when I assign C scales, it plays the C# scale. When I assign the C# scale, it plays the D scale.
The weird thing is also that the other scales : E, F, F#… to B, are OK. There is no problem for these scales.
I don't understand how it did happen, and how I could fix it. Could you help me please ?
