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 .
C3
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
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 .
