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.

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.

TyrellN6
TyrellN6 is a compact, sporty synth. Based on concepts and ideas for a hardware synth: a few modules, novel features, analog sound, and low cost. TyrellN6 is the software version manifestation of these ideas. Available as a free download exclusively from the German online magazine Amazona. TyrellN6 is a free virtual analog synthesizer developed by u-he, inspired by the design of classic hardware synths like the Roland Juno 60. It features two oscillators, noise, a ring modulator, and two LFOs with eight waveforms. The audio source mixer includes authentic overdrive and filter feedback, while the twin filter is related to u-he's Diva synthesizer. TyrellN6 supports unison with up to eight voices and offers analog-type ADSR envelopes that are loopable or LFO-triggered. A small modulation matrix with depth modulation from a second source, a chorus effect with three modes, and MIDI learn/unlearn for hardware control are also included.

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.
