hello list-members,

dieter doepfer contacted me and pointed out that
the early filters were designed in a way that no
distortion can occour when using a100 signals.
this behaviour can be changed by simply changing
a resistor in the input stage. with this change
the earlier filter models like a120 can also be
overdriven, just like the a108.

best wishes
