Vintage B3 Main window in Logic Pro for Mac
The Vintage B3 Main window is divided into three areas. The draw bars change the basic organ sound in real time. See Vintage B3 draw bar controls. Click the Control, Preset, and Split buttons at the lower right to show different parameters below the draw bars. The lower edge gives you direct access to Leslie speed controls.
The Scanner Vibrato, Distortion Drive, and Percussion controls are shown below the draw bars when the Control button at the lower right is turned on. These add a vibrato or chorus-like effect, an overdrive, or percussive element to your organ sound. See Vintage B3 Scanner Vibrato and Chorus, Vintage B3 Distortion effect, and Vintage B3 Percussion effect.
The Preset (registration) and Morph controls are shown below the draw bars when the Preset button at the lower right is turned on. See Use Vintage B3 preset keys and Vintage B3 Morph parameters.
MIDI keyboard controls are shown below the draw bars when the Split button at the lower right is turned on. See Vintage B3 MIDI setup overview.
