Does this work as I’m imagining it?
Is the Q-Slider output suitable for controlling the CV input of the A-130-8V in this way?
Would this give me a useful and reasonably smooth range for manual volume performances?
Are there any problems with using the Q-Slider's M-IN / MAX settings to calibrate the VCA range?

Yes, that will work as you describe, though you will have to make adjustments to the A-130-8. The QSlider outputs either 0-10V or +/-5V. The A-130-8 expects 0-5V "out of the box", but it has trimmers on the back that you can adjust to get 0-10V instead. So you would set the QSliders to 0-10V and then adjust the A-130-8 to match. That would do exactly what you want.
