KEYBOARD
The
SH-7
keyboard
has
44
keys
for
a
range of
3-1/2
octaves,
but
by
use of the
VCO
RANGE
switch
and
the
CONTROLLER
section
TRANS-
POSE
switch, the
SH-7
has a
total
pitch
range
of over nine octaves
which
covers the
full
range
of
human
hearing.
With
the
RANGE
switches
at 8'
and
the
TRANS-
POSE
switch
at
M,
the lowest
C
on
the key-
board
corresponds
to
middle
C
on
the piano.
KEYBOARD VOLTAGE
The
keyboard produces
a
control voltage
which
corresponds
to
the
key
pressed. This control
voltage
is
most
often
used
to control
a
VCO
so
that
it
produces
the pitch related to the
key
pressed.
The SH-7
uses the relation
of
1
volt/1
octave
(one
volt
per octave)
which means
that
a
one
volt
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
equip-
ment.
This
means
that
the
SH-7
is
compatible
with
most equipment
used
in
electronic
music.
