KEYBOARD
KEYBOARD
The
SH-1 keyboard
has
32 keys
for
a
range
of 2-1/2 octaves, but by use of the
VCO
RANGE
switch
and with
the
CONTROL-
LER
section
TRANSPOSE
switch, the SH-1
has a total pitch
range of over eight octaves.
With the
RANGE
switch
at
8' and the
TRANSPOSE
switch
at
M, the iowest
C on
the
keyboard
corresponds to middle
C
on
the piano.
KEYBOARD VOLTAGE
The keyboard produces
a
controi voltage
which corresponds to the key
pressed.
This
control voltage
is
most
often used to con-
trol
a
VCO
so that
it
produces the pitch
related
to the key
pressed.
The SH-1
uses the relation of
1
volt/1
octave (one
volt
per octave)
which means
that
a
one
voit
change
in
the control voltage
will
produce
a
one octave change
in
pitch.
The
relation
is
very
common
and
is
used on
most
synthesizers
and
related
equipment,
including professional studio
equipment
as
well
as
stage
type equipment. This
means
that the
SH-1
is
compatible with
most
equipment
used
in all
forms of electronic
music.
