Pedal Drawbars
The organ features two drawbars for the bass Pedals. The waveform of the bass is not a
pure sine wave, but a mixed waveform, that realistically simulates the Hammond B3
bass. The two registers differ in pitch, and in the following ways:
• the Lower 16' register contains more octaves
• the 8' register has a more prominent fifth portion.
Volume
Relative Volumes—Upper/Lower/Pedal
In the Organ parameters section, you can set the volume of the Lower manual, and the
Pedal, relative to the Upper manual. The parameters are called Lower Volume and Pedal
Volume.
Volume Control and Expression Pedal
The overall volume of the EVB3 is not only controlled by the Audio Instrument volume
fader and control change #7, but also with the Volume control in the EVB3 graphic user
interface.
Warning: The Volume must be lowered whenever crackling or other digital distortion
occurs in the Audio Instrument channel. Volume levels over 0 dB can occur if you
maximize all registers, play numerous notes, and make use of the Distortion effect.
You can control the volume in real-time with an Expression Pedal (Swell Pedal).
Extensive, and 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 preamplifier. Bass and treble are not attenuated as strongly as the mids, much
like a Hi-Fi amplifier that features a loudness correction facility.
Normally, you would connect an Expression Pedal to the quarter inch Expression jack of
your master keyboard. Your master keyboard should transmit MIDI control change #11
when the pedal is moved.
