[sdiy] Continuously variable waveshaping (was Behringer Neutron)

[Dan Snazelle]

I'm often amazed at how Broad a patent can be . 

I'm not sure about which of this individually is totally new except that they are applying it to an analog core ..if they were aggressive about protecting this I wonder what elements of many current analog designs which implement Pwm , mcu or switches to control things would infringe on their patent. 

I'm not implying moog would do That but I'd love to know more about why this is totally unique . 



To me it looks like Mcu /high quality automotive pwm chips and many normal analog synth blocks and components as well as  system wide thinking ....

many people think on a system level to put a bunch of cool features together but is that what allows a patent ? Surely other products have used Pwm in this way (to control integration ) 

Or is what's unique combining all the slope voltages ? That doesn't seem unique either in the digital realm (yes it's controlling an analog core but .,,,)


Please help me understand what is so revolutionary here ?
