As an example of what this means when
you
play, let us see which note can be produced by
using one of the tone levers and pressing the
key of middle C (с). Pressing middle C and using
the 4' tone lever, for example, will result in the
same
note as would
be produced
by pressing
c2 (using the 8' tone lever, i.e. its Fundamental.)
It can thus be seen that the use of these harmonic
levers actually results in increasing the YC-20
Combo Organ's compass above and below that
which is indicated by the keys alone.
The use
of the 16' lever, for example,
will
extend
the
manuals
down
a further
octave
to Сі.
(See
dotted line-above). Similarly the 1' lever raises
the tone three octaves
but, in actual
practice,
the highest note on the YC-20 is bs. Thus when
a scale
is continued
upward
beyond
bz, the
previous octave is repeated. This is no cause for
alarm. It is inherent in the design of the YC-20
and
will
cause
you
no
inconvenience
at all
when playing.
The major use of the harmonic levers, however
is to increase the richness of tone—they
are the
spices that, when
applied to the
fundamental,
will give
big
full sound
to the
performance.
Let your ears be your guide to the creation of
good music, try not to over-work the full effect
as this will weaken
its effectiveness.
Change
your registration as often as the mood
of the
music requires.
CH.1@
(16'0,8'9.40.2:'0,2'D,
120.10)
If the Balance Lever @ is set to the "0" position
(far side), the tone color of the Manual Keyboard
can be selected by a combination
of the CH.I
tone levers.
The CH.I tone color is the basic sound of the
Combo Organ.
CH. ІІ & (16' 0,8 9,4
p.29)
If the Balance Lever @ is set to the "3" position
(near
side),
the
tone
color
of the
Manual
Keyboard can be selected by a combination of the
CH.II tone levers.
The tone color of CH.lI can be widely changed
by operation
of the
Bright
Lever(B.
If the
Bright Lever is set at "O';aflute-family tone color
(a tone color with less overtone) can be pro-
duced.
if set to "3", a string-familytonecolor
(with rich overtones) can be produced.

When the Balance Lever @ is set to the middle
position, tone

Keyboard
can be selected by a combination of the CH.I
and CH.II tone levers(9 (8.
Volume (Master Volume)
Although
this
control
actually
belongs
to a
group of OTHER
CONTROLS (page 70), it will
be described here because it has a relationship
with the Tone
Levers. The tones selected with
the maximum volume of the tone levers of СН. I,
CH.Il and Manual
Bass are regulated with this
control.
Manual Bass@ (16'0,8'0)
If the Manual
Bass lever @ is operated (set to
near side), the 17 bass keys identified by reverse
key colors, are changed to produce bass tones.
Tone color is selected by a combination of the
16' and 8' Manual Bass Tone Levers.
Bass Volume@
This also belongs to a group of OTHER
CON-
TROLS
(described
later).
