TRIGGERING
switch.
In
the
single
mode,
no
new
triggers
can
be
generated
until
all
keys
are
released.
In
the
multiple
mode,
a
new
trigger
is
produced
every
time
the
keyboard
voltage
changes.
KEYBOARD
FORCE
SENSOR:
Produces
a
control
voltage
proportional
to
amount
of
force
applied
to
the
keyboard.
This
signal
may
be
used
either
directly
(BEND)
or
to
control
the
amount
of
a
selected
signal
(MOD)
from
the
SOURCE
selector.

through
reversible
attenuator
for
positive
or
negative
sweeps
up
to
5
octaves.
FREQUENCY
MOD.
BY
OSC:
Injects
tone

MODULATION
MODULATION
OSCILLATOR:
Produces
a
50%

square
wave
and
a
triangle
wave.
Supplies
trigger
to
sample-hold
and
may
be
used
to
trigger
contour
generators.

control.
SOURCE
SWITCH:
Selects
source
of

modulation.
ROUTING
SWITCH:
Selects
destination
of
wheel

that
varies
the
amplitude
of
modulation
fed
to
the
ROUTING
switch.
