Rubigo Audio | Precision Organ Emulation

How we build them

Model the machine, not a recording of it.

Rubigo plugins aren't sample libraries. They compute the physical parts of the original instrument as you play: the tonewheels, the spinning horn and drum, the tubes and transformers. Every model is built from measurements and from the circuits themselves.

Measured, not guessed

The tonewheels' harmonics, bleed, hum and drift are measured from four real organs. Each rotary cabinet is fitted to that cabinet's measured response.

Controls with physical meaning

The horn's radius, the microphones' distance and angle, how hard the amp is pushed. Change them and the model is rebuilt from your settings: no crossfading between recordings.

The circuit, not a preset curve

The preamp and the cabinet's tube amp come from their real components and datasheets. A neural network is trained on the circuit's own behavior, down to its growl.

One engine, every product

Rubigo Rotary is the rotary cabinet and amp inside Rubigo RB3, as its own plugin: the same code, so it sounds the same in both, and every improvement reaches both.
