In Fast Tracker 2, there was a button called 'Adv. Edit.' Its most useful feature was the bunch of tick boxes that let you choose what was and wasn't copied and pasted by those respective commands - you could also choose what was ignored entirely with the 'transparent' option.
Does Madtracker have this feature? I can't find it, but the last time I thought a feature was missing, I was wrong.
It's incredibly useful for copying and pasting effects or volume levels without wiping your note data.
