Vintage B3 Microphone settings in Logic Pro for iPad
Vintage B3 provides modeled microphones that pick up the sound of the Leslie cabinet. You can set the listening position with these parameters. See Vintage B3 basic Leslie controls for an overview of the Leslie rotator cabinets commonly paired with the B3.

Microphone parameters
Horn/Drum Mic pop-up menus: Choose a microphone type for the horn and drum speakers when Real Cabinet is chosen in the Cabinet pop-up menu in the Rotor Cabinet section.
Dynamic: Emulates the sound of a dynamic cardioid microphone. This microphone type sounds brighter and more cutting than the Condenser mic.
Condenser: Emulates the sound of a studio condenser microphone. The sound of condenser microphones is fine, transparent, and well-balanced.
Mid-Side Mic: A Middle and Side (MS) configuration where two microphones are positioned closely together. One is a cardioid (or omnidirectional) microphone that directly faces the cabinet—in a straight alignment. The other is a bidirectional microphone, with its axes pointing to the left and right of the cabinet at 90° angles. The cardioid microphone captures the middle signal to one stereo side. The bidirectional microphone captures the side signal to the other stereo side.
Mic Position switch: Choose either the Front or Rear position for the virtual microphone.
When Real Cabinet is chosen in the Cabinet pop-up menu in the Rotor Cabinet section:
Horn Width knob and field: Define the stereo width of the Horn deflector microphone.
Drum Width knob and field: Define the stereo width of the Drum deflector microphone.
When other cabinets are chosen in the Cabinet pop-up menu in the Rotor Cabinet section:
Mic Distance knob and field: Determine the distance of the virtual microphones (the listening position) from the emulated speaker cabinet. Turn to the right for a darker and less defined sound.
Mic Angle knob and field: Define the stereo image by changing the angle of the simulated microphones between 0 and 180 degrees.
Balance slider and field: Set the balance between the horn and drum microphone signals.
