It's alright.
You're talking about TONTO right? It was mostly a moog system, but it had ARP modules in it too. Must've been a herculian effort to get it all running, building a monophonic modular is tricky itself. They've turned it into a mostly software modular during the latter days, I think.
I was looking at serge, but I'm not a fan of banana plugs. Sure they're more flexible for routing, but it'll be hassle converting them to fit on my doepfer if I ever wanted to use serge modules with it.
