Do you really use all six pins of the 16way connector for ground In the
picture http://www.doepfer.de/a100_man/a100t_3.gif you can see, that six
pins are used (if I name them like the pins of an DIL-ic, than they are
the pins 2, 6, 7, 10, 11, 12).

Could you proove the "crosstalk" by mounting only one LFO and one VCO to
the case
