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.
