All the jacks I've looked at on Doepfer modules are Switching types, though
the switching function is seldom used. They use this type of jack because it
has more legs to go through the PCB (stability and strength), six instead of
three. Most of the modules have traces bridging across both the switch and
contact legs. I was going to use the switching leg to make a "normalized"
synth starting patch, the common VCO-VCF_VCA sort of thing, but because the
traces are sometimes on both sides of a double sided PCB, you would have to
remove the jack to cut the top trace. It would be nice if Doepfer did what
the old Emu modular did, offer all the switched contacts on the PCB with
headers that you could wire to. If the Switched contacts on the Doepfer
jacks just went to unused pads (cheaper than headers) that would be very
useful for making normalized patches, mot to mention making a Vostok type
synth with a ARP 2500 switch bank or EMS patch matrix that always could be
overridden with a patch cord.
