Thanks for the reply, and I really appreciate the help! I guess I'm used to thinking of things much like a simple guitar pedal signal chain, with each unit simply taking that one signal and modulating it with its own flavor, etc. and passing it on. So I hadn't considered the usefulness of a mixer. Also I know sequencers are huge in the modular world but I'm not big on them. My plan is to play music through it via MIDI keyboard, and to modulate/manipulate the sound via the various eurorack knobs.
You'll see I've just updated this sketch by adding a dual LFO (mainly for modulating the braids and the Modal 008), and adding a Clouds (more modulation) and a tube mixer before sending it to the Strymon. Do you think this would be a pretty complete setup for what I'm trying to do? Also, perhaps I'll need a MIDI converter, like a Yarns? Thanks!
-EDIT-
I've just added some sequencing options for manipulating clouds, etc., and a duophonic MIDI interface.
