The module is based on an idea by Donald Tillman from 2003 but has been revised for the use of modern electronic circuits (no OTAs CA3280). Because of it's unique trapezoid core it's totally different compared to other VCOs. But the trapezoid core is not the only specialty: it is also a quadrature VCO and features linear thru zero frequency modulation. The term "quadrature" means in this connection that
