Signal chain order support would be tight.

Wouldn't work in a modular synth context. With effect pedals, things are a bit more obvious, but with a modular synth, technically anything can go anywhere. For example, you would normally not use a VCO to control a VCA...UNLESS, of course, you're using the VCA to produce FM on the other signal that's being fed through it. Similarly, a VCF isn't supposed to be a sound source...but if you crank one into self-resonance, then it can be.

The whole point of modular synthesis is that as long as you're not connecting outputs to outputs or inputs to inputs, you can potentially get some sort of result. Not all of these will be useful...but some will be downright mindblowing.
