Thank you so much to both of you for the insight on this - I've managed to make a bit of a workaround for the time, and it seems to work rather well (albeit yes, at the expense of having to sacrifice a block or two or change the parameters to keep them consistent).
I definitely understand why they don't let you mix multiple effect parameters to one controller (or in my case the mix of a delay, say, to both EXP 1 and EXP 2) but that would make things *slightly* easier.
Nonetheless, question answered, so again thank you!
