yup, you guessed right, it is sampled once per engine iteration. There's
no short term plans of addressing this, so the practical fix for now is to
just use a smaller block size (-b). Some chainops (in practise LADSPA or
LV2 plugins) may do parameter smoothing, but this is not implemented in
ecasound's own internal chainops.
