On top of all that, I doubt that the CV input is connected directly to any analog sound parts like the filter for example... it's most likely converted to digital for the modulation matrix, and the modulation matrix does not run at full audio rate anyway... pedal/CV input is available as a modulation source, so I think that in any case, without an analog filter on the input or not, it would not make much sense since the modulation matrix is running at a slow rate anyway. I bet the filter in the pedal input is calibrated so that no frequencies above the mod matrix's will be let thru.
