Like the filters, Diva’s oscillators are also modelled on classic hardware. All filters have modulation options and the traditional cutoff and resonance controls, but each has its character, quirks and options. (If you are interested, Urs wrote an in-depth blog post about ZDF.)ĭiva models five different filters found in classic hardware synthesizers. With ZDF, the delays normally produced when modelling analogue circuits are vastly reduced, resulting in a much more authentic resonance behaviour. A combination of realtime circuit simulation and zero delay feedback (ZDF) design gives Diva its remarkable sound. The filters are at the heart of Diva’s analogue sound.
