Auto Bass/Chord Section
This section
is comprised
of the Auto
Bass/Chord
lever
and
Bass Variation
selectors, all located at the far left of
the lower manual.
It works in conjunction with the rhythm
selector buttons of the Auto
Rhythm section.
If you play a lower manual chord without the Auto Bass/
Chord
lever on, it will sound
in the ordinary way, with
all notes beginning when pressed, and ending when released.
By sliding down
the Auto
Bass/Chord
lever, however, an
automatic
memory
system couples the rhythm section to
the lower manual keys and pedals so that the pressed chord
will be played one note at a time according to the selected
rhythm and bass variation.
This rhythm pattern will con-
tinue as long as the chord is held down, and fingering is
not necessary.
First select the rhythm desired, and set the speed.
Switch
on the Auto-Rhythm
Synchro-Start
switch, and turn the
Auto
Rhythm
Volume
knob all the way to the left (off).
Pull the Auto Bass/Chord Lever forward (on).
Set the Sustain, Bass
16', Bass 8' and Bass Guitar levers
to the desired positions.
Push one of the Bass Variation buttons.
Note:
When
the
Auto
Bass/Chord
is on, the rhythm
sounds
of
the
Lower
Manual
are
limited
to
Horn
8', Cello 8' and
Cello 4'.
In other words, these are the only Auto Bass/Chord
sounds obtainable.
Now,
as soon
as a lower
manual
chord
(major,
minor,
seventh
or minor
seventh)
as pressed, the rhythm will go
on, but instead of rhythm
instrument sounds the rhythm
will be played as a variation upon the pressed chord.
