Does anyone know if the Prophet VS worked like this too? (Aaron? Don't you have a VS in your rack somewhere?)

It seems like more sums than are really necessary, but I suppose it has the advantage of getting you closer to having just a single oscillator when the stick is pushed to an extreme. I should really have a play with this.
