Diva: Dinosaur Impersonating Virtual Analogue synthesizer.
Diva captures the spirit of five decades of analogue synthesizers. Oscillators, filters, and envelopes from some of the greatest monophonic and polyphonic synths of yesteryear were meticulously modelled for unmatched analogue sound. More than a single synthesizer: Recreate an old favourite or mix-and-match modules to design your unique hybrid.

Diva captures the spirit of various analogue synthesizers by letting the user select from a variety of alternative modules. The oscillators, filters and envelopes closely model components found in some of the greatest monophonic and polyphonic synthesizers of yesteryear. But what sets DIVA apart from other emulations is the sheer authenticity of her analogue sound. This comes at the cost of quite a high CPU-hit, but we think it was worth it: Diva is the first native software synth that applies methods from industrial circuit simulators in realtime.
One spirit, many flavours
Oscillators and Filters
The filters are at the heart of Diva’s analogue sound. A combination of realtime circuit simulation and zero delay feedback (ZDF) design gives Diva its remarkable sound. With ZDF, the delays normally produced when modelling analogue circuits are vastly reduced, resulting in a much more authentic resonance behaviour. (If you are interested, Urs wrote an in-depth blog post Link about ZDF.)
Diva models five different filters found in classic hardware synthesizers. All filters have modulation options and the traditional cutoff and resonance controls, but each has its character, quirks and options.
Like the filters, Diva’s oscillators are also modelled on classic hardware. The five models offer a wide range of different characteristics that fundamentally affect the overall sound, giving you a broad palette to start with for your next riff, bass and pad.
All five share common controls: waveform selection, octave range, mix or independent output volume controls, a noise source and plentiful modulation options. Plus a few touches unique to each model.
Oscillators Triple VCO Dual VCO DCO Dual VCO Eco Digital
With three oscillators, Triple VCO is the largest of the oscillator panels. Waveform shape selection is continuous rather than discrete: choose ramp, triangle, sawtooth, square or any position inbetween for hybrid shapes. Try out frequency modulation (FM), oscillator sync, waveform modulation for striking tones. Use feedback to route post-filter sound back into the oscillator mixer for effects ranging from mild bass boost to subharmonics / low-frequency howling.
A bit simpler than the Triple VCO, but still extremely capable. Multiple waveforms can be activated per oscillator for rich and diverse sounds. Pulse width modulation (PWM), sync and cross modulation (FM) are available. Select one of three hardware revisions for different characteristics.
DCO This is the only single oscillator model in Diva, but a few special tricks make it a worthy addition. The oscillator is multi-wave, summing four sources: pulse, sawtooth, suboscillator and noise, so the final sound can still be quite complex. Try the DCO whenever you need a crisper sound than the other analogue oscillators provide.
A simpler panel for a more CPU-friendly model—a pair of oscillators with independent tuning and multiple waveforms. While neither PWM nor FM are included, this model does offer ring modulati
Digital? In Diva? Yes, it is true. This addition models all the grit and “flaws” of the original and broadens Diva’s palette of sounds admirably. Digital includes very different waveforms, most notably Multisaw, which is great for rich pads. More common waveforms such triangle and sawtooth can be warped and modulated for intriguing results.
Dual VCO Eco
Sallen-Key topology for a very distinctive character and intense resonance. Switch between two revision options.
Effects and envelopes
Oscillators and filters get your sound humming, but a little polish and refinement make it sing.
Switching oscillators and filters on or off like an organ would be very limiting. Envelopes provide more nuanced and engaging results. Diva has two slots—one dedicated to the amplifier, the other to the filter—both with three models to choose from. Craft gently rising sounds, notes that fade slowly into the distance, or sharp percussion.
As a final touch you can put Diva’s two stereo effects slots to use. In keeping with the vintage feel, the available effects would be right at home in the studios of bygone days. Add space with the plate reverb and delay, or movement with the phaser, chorus and rotary speaker effects.
Small details can transform static, lifeless sounds into something much more lively and organic.
The Trimmers panel is where you can make your sounds feel more analogue. Control voice detuning per oscillator, adjust variance between individual voices (round robin), voice drift and more—adding life to your music. These options mirror the inherent variations in analogue hardware. As the circuit boards are not always 100% the same (due to component tolerances), oscillator tuning may differ slightly, some envelopes are a little less snappy. The individual effects may be subtle, but they add up to a more authentic analogue sound.
Dive into the Modifications panel for more modulation options and an opportunity to push Diva into more experimental and unusual territories. Modulation processors such as Invert, Add, Quantize and Lag open up fresh ideas for manipulating Diva. These capabilities take Diva beyond the original hardware that inspired it.
