Thank you both for the insight. I’ve taken i to consideration the recommendations made here. I sat down with the two pieces I do have last night and got to figuring some things out for myself. What I think I know about how synthesizers work, gained from working with VSTs in DAWs. That being said I realize how I would benefit from different filters so an MMF keeps coming to mind I have 15 slots for modules in the case, so plenty of room. I do like the idea if going aftera filter and the rampage next, maybe even a dedicated ADSR type module. I find myself constantly tweaking those in software side of things. What a rabbit hole I’ve found. I have a version two of this rack with mindphaser as the central piece, it’s so easy to get sidetracked
