I'm finding this to be the case. I'm not much of a Deep Diving kind of guy, so I have found several Filters, Octaves, and combos of each, that are close to what I'm looking for, then I edit and save on the pedal. I had the C4, and swapped it out for the Spectrum for this reason.
Yes I suspect the Spectrum is easier for using live tha the C4. The C4 has more options and sounds but if you are more interested in the envelope filters sounds you might be better of with the Spectrum (?).
