Despite its high-fidelity sound, it is designed to run smoothly within the Reason DAW without taxing the CPU. An organ is only half of the equation;

Users can patch Control Voltage (CV) into the back of the device to automate drawbar movements or rotary speed with LFOs.

Users can toggle between slow (chorale) and fast (tremolo) speeds.

At the heart of the Combo B3 is a sophisticated modeling engine that replicates the unique way tonewheels generate sound. Unlike modern synthesizers that rely on clean oscillators, the B3 sound is inherently "imperfect." The Combo B3 emulates:
