The outputs don't go to the next input, rather they are mixed with the next output if unpatched.

Yuppers...it's called a "breakable mixbus". For example, you can input signals and have the module do the mixing, or you could break out two on each side to have dual 2-1 mixers for stereo. And so on...
Also, what exactly are these VCAs destined to do? There's two types, linear and exponential, and they're VERY different. Linear VCAs are for modulation, etc as they deal with control voltages in a linear fashion. But exponential VCAs are for audio, since these behave in a similar exponential manner with how we perceive loudness...like the Decibel scale, each time you go up by 1V, your level changes x10. Plus, there's DC-coupled and AC-coupled. If you're aiming to control the amplitude of signals below the range of human hearing and down to DC, you have to have DC coupling. But having DC-coupled VCAs in the AUDIO path can be potentially problematic...as in, if some DC offset goes thru the outputs of the synth, into your amp, and into the monitors. At that point, your monitors are 100% DONE if that offset level's hot enough. AC-coupled VCAs, however, won't do this as they have a frequency limitation. Hitting an exponential VCA with a DC offset in the audio signal should result in...well, nothing as far as that offset's concerned.
