The

sounds

ously

keyboard,
or
LEAD
VOICES.
|
Cause
and
Solution
|
;
Noise
may
be
produced
when
either
an
electrical
appliance
is
turned
ON/OFF
or
an
electric
power
tool,
such
as
a
drill,
is
used
in
the
proximity
of
the
Electone.
In
such
case,
plug
the
Electone
into
an
electrical
outlet
located
as
far
as
possible
from
the
device
that
seems
to
be
the
source
of
the
problem.
This
is
caused
by
the
proximity
of
a
high-power
broadcasting
station
or
amateur
ham
radio
station.
Noise
may
be
produced
in
such
equipment
if
the
Electone
is
located
nearby.
Use
such
equipment
at
a
location
as
far
as
possible
from
the
Electone.
Because
the
Electone
produces
many
sustained
sounds,
resonance
may
be
caused
in
surrounding
|
objects,
such
as
cabinets
or
glass
windows.
If
it
becomes
а
problem,
relocate
the
resonating
objects
or
lower
the
Flectone’s
volume
:
Because
the
intrinsic
nature
of
electronic
musical
instruments
in
general
is
to
change
timbre,
it
is
+
extremely
difficult
to
eliminate
changes
in
the
volume
of
a
voice
at
different
keyboard
positions,
This
Electone
is
designed
and
adjusted
to
eliminate
any
performance-related
problems.
Its
volume
and
|
timbre
also
vary
widely
according
to
the
installation
site
and
system
configuration
of
the
Flectone,
the
position
of
the
audience,
etc
The
pitch
may
seem
particularly
off
when
compared
to
the
pitch
of
a
piano.
Because
the
harmonic
structure
of
a
piano
is
very
complex,
the
tuning
of
high
and
low
notes
must
be
performed
by
listening,
to
its
harmonic
overtones
rather
than
to
the
actual
sound.
In
contrast,
an
Electone
is
tuned
according
1
to
the
actual
sound,
so
the
pitch
of
an
Electone
and
a
piano
are
inherently
different.
This
effect
occurs
mainly
with
the
voices
of
wind
instruments,
and
is
deliberately
provided
to
recreate
the
characteristic
sounds
of
the
actual
instruments.
It
provides
instrument
sounds
with
realistic
features,
such
as
reed
vibration
or
the
breath
noises
for
BRASS.
|
For
practical
performance
reasons,
this
Electone
has
been
designed
so
that
one
note
can
be
played
at
|
atime
on
the
pedal
keyboard
or
LEAD
VOICES.
If
multiple
keys
are
pressed
only
the
highest
note
will
|
be
sounded
(high-note
priority).
(page

A
maximum
of
seven
notes
can
be
simultaneously
sounded
on
the
upper
or
lower
keyboard.
