Oscillators and FiltersThe 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 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.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.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.Effects and envelopesSwitching 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.Subtle DetailsThe 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.Diva is not a standalone product, it requires host software. Diva is compatible with nearly all DAWs.FeaturesAuthentic, award-winning analogue soundMix-and-match panels for custom layoutsPer-voice oscillator detune and user-definable modulation sourceZero delay feedback (ZDF) filter design for authentic resonance behaviour3 ADS(S)R envelope models based on classic synth hardware with keyboard follow and velocity scaling5 oscillators models based on classic synth hardware5 filter models based on classic synth hardware2 host-syncable LFOs with multiple waveforms, restart options and phase controls2 stereo effects slots, each with chorus (3 modes), phaser (2 modes), plate reverb, delay, rotary speakerHost-syncable arpeggiator with continuous rate offset, swing, various progression optionsMIDI learn page and editable listResizable UI from 70% to 200%Over 1200 factory presetsNEW in v1.4.5: Support for Oddsound MTS-ESP
