on the other hand - with the fx aid (xl)s you do get a hundred plus algorithms to choose from - including 808/909 emulations etc etc... so a lot more flexibility ++++ at least some algorithms on the fx aid are clockable, which is not at all common with fv-1 based effects modules

Yep...is why I don't exactly count the XL as simply another FV-1 device. That might be the core...but HN really outdid themselves with the clocking, piles of presets, et al. It's...ah, different.
