[sdiy] Continuously variable waveshaping (was Behringer Neutron)

[Rutger Vlek]

Agreed! I had exactly the same feeling when reading it for the first time.

I suspect the scope of application (musical instruments) may justify part of its novelty, and perhaps the way the VCO core integrates with an MCU. But is such integration of systems really patent worthy? I'm surprised, and also curious what Moog benefits by having this patented....
