I tried out one of the Preset Packs for my VoiceTone Singles pedal, but I don't like the new sounds and want to restore the Factory Presets. How do I do that?
Simply select all of the presets in VoiceSupport (click the first preset in the list and Shift+click the last preset) and press delete. You should see all blank purple boxes.
Press "Apply Changes" to restore the Factory Presets.
