Rotary Speed
The rotary speaker speed is controlled with
the rotary speed buttons or with an external
pedal connected to the rotor pedal input on
the rear panel.
Press the Slow/Stop button to change the
rotation from Slow to Fast and vice versa.
To stop the rotors, press the Stop Mode
button to activate the Stop Mode and then
the Slow/Stop button (this does not deacti-
vate the Rotary Speaker simulation - it only stops the rotors). When you
press the Slow/Stop button again the rotors will accelerate to the Fast
speed setting. This functionality mimics the behavior of an early, one
speed original rotary speaker.
A connected pedal can be set to change the speeds only when it is
held down or to function like a switch, changing the speed every time
you press it. This functionality is set in the System menu, read more on
this on page 17.
M The actual rotary simulation is activated at the Effects section, with
the Speaker/Comp selector.
Vibrato/Chorus
The Vibrato/Chorus section
mimics the behavior of the
original organs, which means
that these parameters func-
tionality depends on which
model is active. Select the
desired vibrato or chorus type by repeatedly pressing the Mode button.
The Vibrato/Chorus section is common for both the upper and lower
presets, if the split function is active.
B3 – The original tonewheel organ’s vibrato and chorus scanner
consists of a tapped delay line in combination with a rotating scan-
ner. For the Vibrato effect, phase shift is applied to the signal. For the
Chorus effect, a phase modulated signal is added to the original signal.
Three different types of choruses (C1- C3) and three different types of
vibratos (V1-V3) are available.
VX - There is only one type of vibrato available for the VX model, which
is activated using the ON button in the Vibrato section.
Farf - This model has two basic vibrato modes; “Light” and “Heavy”,
with two different rates for each mode.
Percussion
The Percussion effect adds
extra attack to the B3 sound by
having a single envelope gener-
ator controlling either the 2nd or
the 3rd harmonic. The envelope
“opens up” for a short moment
in the beginning of the sound when you press the key(s). The percus-
sion will only affect the upper manual if the Split function is active.
The Percussion is a single-triggered non-legato effect. It is only present
when you hit the keys when no other note is sounding. In other words,
if you play a note or a chord and then add on more notes without
releasing the previously pressed keys, there will be no percussion effect
in the new notes. You have to release all keys to be able to play new
notes with the percussion effect.
The percussion effect is activated and deactivated by pressing the On
button. The Soft/Fast button toggles between normal or soft per-
cussion levels and fast or slow decay times, providing four available
combinations. The Third button toggles between using the 2nd or 3rd
partial as the source for the percussion effect. The percussion decay
times (and levels) can be fine-tuned for Fast and Slow mode individu-
ally. Please refer to the B3 Menu on page 19 for details.
M With the original instrument, you could not use the percussion
effect and 9th drawbar simultaneously. However with the Nord
Electro 4D you have a choice. You can use the percussion and 9th
drawbar together or chose to mimic the original organ behavior by
turning off the 9th drawbar whenever the percussion is activated.
Read more on the Perc Drawbar 9 setting in the B3 menu on
page 19.
Preset/Drawbar/Split
Use the Preset/Lo and Drawbar/Up
buttons to store and recall two sepa-
rate organ settings for each program.
When Preset is active (the LED lit), the
drawbar settings in the preset will be
used, and the drawbars on the panel will not affect the sound. This al-
lows you to use one setting, and prepare the drawbars on the panel with
a new setting to which you can change during the performance.
M B3 Presets will store the Chorus/Vibrato and Percussion settings.
Vox and Farfisa Presets will not store the Vibrato settings, these
are however stored in the program.
When Drawbar is active, the LED will be lit only if the physical position of
the drawbars on the panel matches the settings in the program. If both
the Preset and Drawbar LEDs are off, this indicates that the drawbars are
active but the position on the panel does not match the settings stored
in the program. As soon as you move a drawbar on the panel, the sound
will change to reflect that drawbar’s position.
Hold Shift and press the Preset/Lo button to save the current drawbar
setting on the panel as the Preset. This preset then has to be stored in
the program as well. Edit the settings of the Preset by holding the Preset
button while adjusting the drawbars.
Press the Shift and the Split button to divide the Nord Electro 4D
keyboard in two sections, the Lower and the Upper Manual sections.
By default, the split point on the keyboard is between the keys B3 and
C4. You can, however, also set the split point manually by holding both
the Shift and Split buttons, the split LED starts to flash, then while still
holding the buttons, press the desired key. A set split point is saved as
part of the parameters in a program.
