One nitpick: while the Behringer Neutron is not directly a clone, the VCO V3340 ICs used in the Neutron are clones of the famous CEM3340 by Doug Curtis.
While that is perfectly legal these days, Doug's wife and family worked with people to re-issue the original VCO chip (and others), so it sure would have been nice for Behringer to collaborate with them and pay some tribute to Doug.
