Bazille
Bazille, developed by u-he, is a modular synthesizer that combines digital oscillators with analog-style filters and extensive modulation capabilities. It features four digital oscillators capable of frequency modulation, phase distortion, and fractal resonance synthesis, allowing for complex sound design. The synthesizer includes four self-oscillating multimode filters, each with up to six parallel outputs, providing versatile filtering options. Bazille offers four ADSR envelopes with adjustable fall and rise controls, two LFOs with multiple waveforms and outputs, and a 6-step morphing sequencer with eight snapshots for dynamic modulation. Additional components include mapping generators, multiplex modules for signal mixing and modulation, and built-in effects such as stereo delay, distortion, phaser, and spring reverb. The interface is fully modular, allowing users to connect any output to any input, facilitating intricate patching possibilities.

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.

AudioKit Synth One
AudioKit Synth One is the world's first completely free and open source professional iOS synthesizer app, developed by volunteers to provide a full-featured and ad-free music creation experience. It features a hybrid analog/FM poly synth with six-voice capability, over 300 presets crafted by renowned sound designers, and supports accessibility with VoiceOver for the blind and visually impaired. The app integrates seamlessly with Audiobus 3, and Inter-app Audio (IAA), and is compatible with AUM, BeatMaker 3, Cubasis, and GarageBand. Its sound engine includes five oscillators, two assignable LFOs with numerous routing options, and a vintage-style 16-step sequencer. Additional features comprise a classic poly arpeggiator, Ableton Link support, touchable ADSR envelopes for amp and filter, a 4-pole vintage low-pass filter, high-pass/band-pass filters, and effects such as reverb and multi-tap delay. MIDI integration allows control via MIDI keyboards or DAWs.

Podolski
Created in 2005 and still going strong. Podolski is a free, straightforward, CPU-efficient virtual analog synthesizer. One oscillator, one filter, one envelope, and an arpeggiator/sequencer. Simple, but with a few tricks up its sleeve. Create high-quality sounds with ease. Podolski is a simple, CPU-efficient virtual analog synthesizer. Basically a cut-down version of FilterscapeVA with just one oscillator, one filter, one envelope, and two LFOs, it also features a Zebra-style arpeggiator/sequencer plus chorus and delay effects. Podolski's specialties are the click parameter (which emphasizes the filter attack) and its ability to seamlessly morph between three waveforms (WaveWarp). Oscillator with variable symmetry (sawtooth to triangle, PWM) and glide. Combination arpeggiator/16-step sequencer with extra modulation source. ADSR or HDSR, linear or exponential. Sustain has fall/rise control.
