Originally, this had just the Dual CV Shift, but now there is a simple utility for adding a voltage to several others independently.
The use I had for AddAll was in trying to create a patch similar to the Lyle Mays Oberheim patch from “It’s for You” (AFWSFWF) and a few other Pat Metheny songs. There are several voices, and each oscillator is unison, but each is inflected at the start with envelope subtly different from the others, and so I wanted a simple way of imposing different envelopes on a single V/Oct.
