Diva

Diva (Dinosaur Impersonating Virtual Analogue) is a mix-and-match modular synth built around five interchangeable oscillator models and five interchangeable filter models, each drawn from a different piece of classic hardware. The oscillators range from a three-VCO panel with continuous waveform morphing and FM/sync, down to a single DCO and a digital multisaw model. The filters cover Ladder, Cascade, Multimode, Sallen-Key (Bite), and a state-variable (Uhbie). The key technical distinction is u-he’s use of zero delay feedback (ZDF) design alongside realtime circuit simulation — the same class of methods used in industrial circuit simulators like PSpice — which is why the resonance behaviour sounds the way it does rather than like a standard biquad approximation.

Diva runs up to 16-voice polyphony and ships with over 1,200 factory presets. Its Trimmers panel adds per-voice drift, oscillator phase control, variance, and glide slop options that replicate the component tolerances of real hardware. Two stereo effects slots offer chorus, phaser, plate reverb, delay, and rotary speaker. The CPU hit is real and well-documented, but for analogue emulation that holds up under close listening, it’s the benchmark most others get measured against.
