9. ALL ABOUT VB3
VB3 is the first instrument that can be selected by pushing the button n. 22 labeled
TYPE. It is the simulation of a tonewheel organ and is the main sound engine of your
Crumar Mojo 61. Just like the original organ, it consists of three manuals, the upper,
the lower and the pedalboard, even though we have only one physical keyboard and
one set of 9 drawbars. Nevertheless, Mojo 61 offers some smart solutions to make it
fun and easy to play even without the additional lower keyboard.
First, select which MODE you wish to play by using button n. 15. It is very important,
because the MODE establishes which manual the keyboard plays and which manual
the drawbars must control.
Second, select which manual you're going to play and/or to control, by using the
buttons n. 9 for the upper manual, button n. 12 for the lower manual, button n. 14 for
the pedalboard.
Now an example is given in order to explain how different modes work. Let's assume
that the upper manual is selected.
–
MODE = SINGLE: the keyboard plays the upper manual and the drawbars
control the upper manual registration;
–
MODE = SPLIT: the keyboard is split in two parts, the left part plays the lower
manual, the right part plays the upper manual; the drawbars control the upper
manual (which, in this example, is selected); if we select the lower manual, the
keyboard remains split but the drawbars will now control the lower manual;
–
MODE = EXT. LOWER: the keyboard always controls the upper manual, the
drawbars will control the manual that is currently selected. This is because the
lower manual is expected to be played from an external MIDI keyboard.
The playable extension of the VB3 organ is 61 notes, from C (note 36) to C
(note 96). Applying the transposition would not affect the playable
extension, thus resulting in having mute notes at one of the extremes of the
keyboard.
CHORUS / VIBRATO
VB3 supports the 6 selections of Chorus or Vibrato, just like the original tonewheel
organs, and separate activation on the upper manual and/or the lower manual (that
also includes the pedalboard) by using only one button. When the upper manual is
selected, button n. 7 and its LED relate to the upper manual; when the lower manual
or the pedalboard is selected, button n. 7 works on the lower manual. Of course the
status (on or off ) is remembered.
Shortcut: use button n. 7 along with the SHIFT button
to toggle the effect on the other manual.
