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.

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.

BazilleCM
BazilleCM is a streamlined version of u-he's modular synthesizer, Bazille, offering a compact yet powerful synthesis environment. It features two digital oscillators capable of simultaneous frequency modulation, phase distortion, and fractal resonance, providing a rich palette for sound design. The synthesizer includes a multimode analog-style filter with six parallel outputs, two ADSR envelopes with adjustable sustain slopes, and a low-frequency oscillator with multiple waveforms. A 16-step sequencer with eight morphable snapshots allows for intricate pattern creation. Additional components such as multiplex units for mixing and modulation, a built-in stereo delay, and various audio-rate signal processors enhance its versatility. BazilleCM supports a polyphony of up to eight voices and offers a resizable, skinnable user interface. It comes with over 265 factory presets to inspire creativity.
