Hi Randal,

There is no digital/analogue ground distinction within the bussing and
cabling system, all three pairs of gnd pins on the connectors are
joined at the bus PCB (and probably at the module PCB too). Take a
look at figure 3 on the technical details page here :
http://www.doepfer.de/a100_man/a100t_e.htm for more details.

Cheers,
Adam-V
