Let me start by saying that I own the "V" collection and I use it frequently.
Still I would love to be able to string together whatever modules to get the desired effect or tone that I'm looking for.
I learned to program on a moog system 55. My 1st synth was an ARP 2600. There was a 2600 at my school and I often cross patched them also ran my friends Quadra through the 2600 to great effect.
What I'm getting at is, I would love to be able to patch between module applications. Build custom beasts within Modular "V". We should be able to recreate the Keith Emerson Moog if we want of create the Walter Carlos System 15 or whatever it was the Tomita had. All of the synth applications should be able to cross patch and need Audio inputs and a bussing structure.
