I read in I think Pitch Factor manual, that there is NO AD/DA conversion in this digital effect.
I believe that you are talking about Relay bypass mode, that's the only thing that make sense from what you say and then the answer is yes. when pedal is bypassed signal is switched directly from inputs to outputs and it's not passing through AD/DA converters of the unit. but obviously, if it's digital FX unit, there have to be AD/DA conversion. there is no chance for digital FX without AD/DA conversion.
