Seems like someone has just released something resembling my dream!
This is a polyphonic modular synth (8 voices, 4 VCOs per voice), that is patchable using normal cables, but once you've patched the synth you can store the settings. Next time you want to use it, you can load the patches from memory without using the cables :-D
Niiiiice, just what I want to build!
Update: I was fooled, it's not analogue. Still pretty cool though.
