your linked rack is private, so unviewable
My bad, I was messing with my settings. There's now versions now: The one I referenced in my reply, and a new one that I came up with after thinking a bit more about my options.
The new setup also addresses some things you mention in your last reply. For example, it now has a pretty cool mixer (MISIO) and only one oscillator (ONA). Together with the Neutron stuff I think it's a nice rig. All this thinking about my setup and going back and forth between options at least left me with a pretty good idea of what I want, so that's nice.
I will definitely have a look at the Mantis too! (The TipTop modules are nice and I like their accessible layout.)
