I don’t know specifically about microcosm but it sounds a bit like what I linked below, which I think is an elektron behavior and there’s a workaround mentioned about using a square LFO in half mode to send a different parameter value and reset. Honestly not sure if this is the same root problem as what you mentioned but it’s the first thing that came to mind for me.
Hope that points you in the right direction, good luck either way.
