Vellfire Calibration
(Our Studio)
One part-time creative dedicated to your continuous stream of projects.
Annulus is a polyphonic resonator and effects engine built for sound designers who think in texture, not presets. At its heart is a faithful implementation of the physical modeling engine behind Mutable Instruments' Rings — one of the most celebrated modules in the history of Eurorack — paired with a full effects chain and a visual interface that breathes with the sound.
Six modes. Six physical models. Six complete sonic identities.

Please note: Annulus is offered free of charge and is currently untested in the wild. It has not gone through a public beta or formal testing phase, so it may contain bugs or behave unpredictably across different systems and DAWs. Use it at your own discretion. If you hit any issues, I'd really appreciate a bug report sent to info@erikssonjonas.com, ideally with your OS, DAW, and a short description of what happened. Your feedback directly shapes where this goes next.
