Diva
Diva captures the spirit of five decades of analog synthesizers. Oscillators, filters, and envelopes from some of the greatest monophonic and polyphonic synths of yesteryear were meticulously modeled for unmatched analog sound. More than a single synthesizer: Recreate an old favourite or mix-and-match modules to design your unique hybrid. Authentic, award-winning analog sound. Per-voice oscillator detunes and user-definable modulation source. Zero delay feedback (ZDF) filter design for authentic resonance behavior. 3 ADS(S)R envelope models based on classic synth hardware with keyboard follow and velocity scaling. Host-sync-able arpeggiator with continuous rate offset, swing, and various progression options. 2 host-sync-able LFOs with multiple waveforms, restart options, and phase controls. 2 stereo effects slots, each with chorus (3 modes), phaser (2 modes), plate reverb, delay, rotary speaker.
