The advanced cabinet parameters are divided into three groups: Cabinet, Motor, and Brake. See also Advanced Cabinet parameters and Advanced Motor parameters.
The microphone parameters are described in Vintage B3 Microphone parameters.
Dry Level knob and field: Set the level of the dry signal. This can also be useful if Dry is active for the Output switch.
Output switch: Choose either switch position to modify the Vintage B3 brake mode.
Dry: The rotor cabinet is bypassed when stopped, with a delay time of one second. This is useful when you are using the modulation wheel to switch between fast and slow rotor speeds. If you then switch to brake mode, the rotors are slowed down during the transition to the dry sound.
Rotor: The movement of the rotor is gradually slowed down to a total stop.
Horn/Drum Position knobs and fields: Set an exact stop position for the Leslie horn or drum (bass) rotator. The original Leslie did not provide this type of control. This occasionally resulted in a horn aimed at the back of the cabinet when it came to a halt, leading to a muffled sound.
