I Dream of Wires is the incorrect title for that great documentary on modular synthesizers.
It should be titled: Couldn’t Sleep Because I Read Manuals Too Late at Night and My Brain Wouldn’t Stop Patching.
In the meanwhile, here is where my system is currently at (or will be when two of those modules arrive from, respectively, Poland and down in Southern California). The blank space at the bottom is, indeed, bank. Likely other modules will go before it is filled. We’ll see.
