Patents are another way to protect your designs (Moog filter, Yamaha FM, etc). Many folks on this list soon be able to benefit from this patent: http://www.synthtech.com/extreme/beerhead.pdf What impressed me the most about this is that: a) the abstract uses the word "ambulation". b) prior art is cited to 1912. There is a claim that "audio entertainment devices" can be added to the basic design, so I don't know if I can add a synth in there without facing legal action :) Paul S. OK, back under my rock
