What Type of utility modules?
-- darksoulif you are referring to my signature - effectively all of them - mixers of all sorts, vcas (especially cascading ones), switches, attenuverters etc etc - use for modulation and triggers as well as audio - doepfer almost always has a reasonably priced version of everything (but it looks like you know that already)
