delays, reverbs and lo-fi tape effects are often what I go to for when I try to make ambient ish music

exact modules are down to individual taste but I like Magneto, disting and fx aid xl for a lot of these effects as well as moogerfoogers etc

plus a lot of modulation - run through a lot of utilities

"some of the best base-level info to remember can be found in Jim's sigfile" @Lugia

Utility modules are the dull polish that makes the shiny modules actually shine!!!

sound sources < sound modifiers < modulation sources < utilities
