By offsets are you referring to mixers, rectifiers and inverters? I use the ones in Kinks to good effect with LFOs and envelopes quite a bit now that my Kinks arrived. WMD SSF makes a nice offset combo module as well as Mannequin Cold Mac. How many of these would you recommend per 6U rack that has 3-5 voices? Logic modules are fun as well. I want to get another offset module and logic module.
