Vintage B3 Master and Click controls in MainStage
Master parameters
Tune knob and field: Change Vintage B3 tuning in cents. A cent is 1/100 of a semitone. At a value of 0 c (zero cents), the central A key is tuned to 440 Hz, or concert pitch.
Volume knob and field: Set the overall output level. The Volume knob must be lowered whenever crackling or other digital distortion occurs. Volume levels over 0 dB can occur if you maximize the levels of all registers, play numerous notes, and make use of the Distortion effect.
Expression knob and field: Set the sensitivity for a connected expression pedal (on a MIDI keyboard with an Expression or assignable controller input). Extensive, often rhythmic, use of the expression (volume) pedal forms part of the style of many organ players. The expression control also emulates the tonal changes of the B3 pre-amplifier, where bass and treble frequencies are not attenuated as much as the mid frequencies. Your master keyboard should transmit MIDI control change #11 when the pedal is moved. Vintage B3 defaults to the use of CC #11 for Expression.
