Nope. The basic transister ladder topology is Bob
Moog's, now in the public domain. The idea of tapping
each rung of the filter to provide a separate output
was actually Tony's idea. Doepfer has a well known
reputation of suddenly coming out with modules after
others have published the schematics - even if those
others have specifically placed restrictions on the
use of their circuits for commercial exploitation by
other companies. So how does one deduce whether
Doepfer actually had an original thought versus just
lifting the schematic? By their past behavior. If you
don't publish your schematic, no Doepfer clone. If you
do publish it, a clone appears. Form your own
judgement.
