Well, newer patches with newer functionalities not working in older versions is how things go anyway, right? Vanilla 0-46 patches don't run in 0.45 and so on... there's no way around that I guess.

But I think it's also simpler and more straightforward than introducing flags, arguments and all. It might be unusual, but there are already some objects with similar design, I actually thought of that because of [sampstoms~] and [mstosamps~] - it'd be basically the same design.
