Oxo Synth2: Free Synth1 AUv3 Synth for macOS and iPadOS
Developer François Chabloz has launched Oxo Synth2, a free open-source virtual analog synthesizer that brings the iconic architecture of Daichi Laboratory's Synth1 to modern iPadOS and macOS systems. The release provides a native 64-bit environment for the classic Clavia Nord Lead 2-inspired sound engine without requiring legacy emulation layers. Producers can grab the standalone app and AUv3 plugin directly from the official store.
Modern Architecture with Classic Synth1 Sound
Synth1 ranks among the most celebrated freeware instruments in digital audio history, yet its lack of active development left Apple Silicon users dependent on Rosetta. Oxo Synth2 recreates the familiar dual-oscillator framework while improving accessibility for touchscreens and high-resolution monitors.
- Up to 32 voices of polyphony with unison support
- Dual oscillators with FM synthesis, ring modulation, and hard sync
- Dedicated noise generator and sub-oscillator
- Multi-mode resonant filter section with low-pass, high-pass, and band-pass curves
- Integrated modulation envelope, dual LFOs, and built-in arpeggiator
- Scalable user interface with integrated color theme options
Seamless iPadOS and Desktop Workflow
Because Oxo Synth2 operates as an AUv3 plugin, it integrates smoothly into mobile and desktop hosts including Logic Pro, GarageBand, Cubasis, and AUM. The code base is open-source, giving the community a reliable path to preserve these classic patch libraries long after older 32-bit versions become obsolete.
Oxo Synth2 is permanently free to download as an AUv3 plugin and standalone app via the Apple App Store.
