The Usual Suspects Osirus v2.2.2 [FREE]

Osirus is a free VST plugin that recreates the Access Virus B and C hardware synthesizers using the DSP56300 emulator, so you can get the classic virtual analog sound in your DAW. It offers a three-oscillator engine with wavetable synthesis and morphing, dual multimode filters (low-pass, high-pass, band-pass) with real-time envelope control, and a modulation matrix for deep sound design. Onboard effects include reverb, delay, phaser, and distortion. With 16-part multitimbral capability, it handles complex arrangements and live performance. Osirus is aimed at hobby producers and sound designers who want the Virus character without the hardware, and it runs on macOS in VST2, VST3, AU, and CLAP formats. Whether you’re making vintage analog tones or experimental textures, Osirus gives you a flexible instrument for your productions.
