If you connect two or more outputs via a passive multiple you generate a short circuit between the outputs. It depends upon the
output circuits what will happen. In the worst case one or more of the circuits may be damaged (that's not the case for A-100
modules as the outputs are protected against such patches). If you are lucky you will obtain something similar to mixing of the
circuits. But the output circuits may also interact and you obtain a result that depends upon the output circuits (e.g. kind of
clipping or waveshaping or other non-linear effects).
