yes, i do understand the use of a dc-offset. or the
use of a VC dc-offset. but you can do all these with
other doepfer modules already... i too use dc-offsets
all the time.
in fact modules that offer dc-offset are:
a129-3, a138, a133, a167, a176, a130.(and for VC
dc-offset you just use a dc-coupled vca after the dc
offset...)
do we need one more module for offsets
