Thanks for the tip re: posting and for the feedback on the rack. Good points to consider.
A number of the modules I have were deals on eBay (Function, Doepfer VCA, ring mod, Steppy, and both filters) before I had much idea where I wanted to go.
I have been looking at adding an attenuverter and a better filter choice and appreciate the confirmation on where to make changes.
I had thought the tides and function for envelopes but have been looking at something simpler - and agree that smaller LFO would help with space too.
I'll check out the Disting EX and add a noise source - opinions on which modules to check out? I have been leaning toward Doepfer for simplicity and size for EG, noise, LFO...
