...but then maybe not. Compare some descriptions against those for
the Doepfer 'equivalent', for example.:

913 - 114 ring mod
903 - 118 noise
916 - 170 slew limit
911A - 162 trigger delay

They are virtually word-for-word copies! Perhaps Dieter has decided
to enter the expensive end of the market with some Moog look-alike
stuff under a different trading name, or has licensed his designs to
someone else for that purpose; either that or whoever is behind it
has done a particularly clumsy job of ripping it off!
