It's so *cheap*, and they are making any possible compromise to keep prices low. While I do *not* know what's inside the A-100 (so don't take this for absolute truth!), it's easy to guess. You all know those 3-way switches that really are "on-off-on" type. So You can switch another capacitor or resistor into Your circuit in the upper and lower position, but not in the middle position. This should explain all. Well, I use these switches for my own projects, too. They are easy to come by, and easy to mount on a front panel. But I am usually working out a trick to avoid this non-subsequent layout. There is *always* a way, but it's always a few components more. And these are too expensive for Doepfer, obviously ... Sometimes I wonder why he uses Jacks on the front panel at all. There are these cheap alligator clips that can be connected to resistor wires on the pcb directly, no? (;->) JH.
