B3 Drawbars
The harmonic intervals for the tonewheel organ are printed on the panel
below the drawbars.
For basic drawbar operation, please refer to “Drawbars and Buttons”
on the previous page. Each drawbar represents a partial with a fixed
harmonic interval in relationship with the played note.
The illustration below shows the pitch interval among the nine drawbars
when the key of C3 is played. Note that the SUB3 drawbar actually is a
5th above the fundamental harmonic. However, in most situations it is
perceived as sounding below the basic harmonic.
Vibrato & Chorus
The original vibrato and chorus scanner in a tonewheel organ consists
of a modulated delay line in combination with a rotating scanner. For
the Vibrato effect, phase shift is applied to the signal. For the Chorus
effect, the 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. Select one of these types by pressing
the Vibrato/Chorus selector button. The effect can be activated/deacti-
vated for both Slots individually by pressing the Vibrato/Chorus button
for the Slot A and Slot B “manuals”.
Percussion
The Percussion effect adds extra attack to the sound by having a single
envelope generator controlling either the 2nd or 3rd harmonic.
The envelope “opens up” for a short moment in the beginning of the
sound when you press the key(s). The percussion is a single-triggered
non-legato effect. By “single-triggered” we mean that the percussion 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 percus-
sion effect in the new notes. You have to release all keys to be able to
play new notes with the percussion effect.
The Volume Soft button toggles between Normal and Soft percussion
level. The Decay Fast button toggles between Slow and Fast decay
times.
Percussion Soft Percussion Normal
The Harmonic Third button toggles between using the 2nd or 3rd
partial as the source for the percussion effect.
E The percussion can be used on Slot A or on Slot B provided that
both slots are not active at the same time in a layer or split key-
board configuration. If you use a layer or a split, then percussion
will only be available on Slot B.
Key click control
The key click produced by the random contact bounces is an impor-
tant audio artifact in the B3 model. This quickly became a desirable
effect amongst musicians. You can adjust the click level in the Sound
menu, read more about this on page 43.
 Do not forget to try out the three tonewheel modes that are also
available in the Sound menu. These will dramatically change the
sound of the B3 model from a squeaky clean unit to a battered,
old workhorse.
Organ Preset I & II
You can store two organ presets/settings within a single program,
and also separately for Slot A and Slot B, for each organ model. This
provides a quick way of changing between two organ sound variations,
without having to change programs or slots.
You change between Presets I & II by pressing the Preset II button. A
preset stores the drawbar settings and the Vibrato/Percussion (on/off)
settings.
