1
Position
Gate Assignment Switches:
Supplies
a
+14
volt
gate to
one
of three
(bused
)
outputs.
2
Foot
Switch
Input: (Rear
Panel)
Sup-
plies a
+14
volt
gate to the
"Foot
Switch
Out"
jack
on
the front
panel.
3
Position
Gate Bus Ou!pufs;+14
volt gate
outputs
which
are usually
connected
to
external
envelope
generators.
4
Position
1
Output:
Supplies
a
+14
volt
gate
on
position
1
(only) to
synchronize
additional
sequencers
or
synthesizers.
5
Clocked Gate Out: Allows
the
selection
of particular position gates
(Gate
Bus
1)
with
control of the pulse
width
(Clock).
6
Clock Out:
Supplies
a
+14
volt
clock
pulse
which
can
trigger
external
envelope
generators.
7
Quantized
CV
Oufputs.-Provides
a
con-
trol
voltage
in
1/12
volt
increments
(0
to
+2
volt range)
which
controls the pitch
of external
oscillators.
The
A
and B
out-
puts
are
common
in
the
16
X
1
mode,
but
separate
in
the
8X2
mode.
8
CV
In:
Allows
external control voltages
(from
a
keyboard
for
example)
to
be
summed
with
the sequencer's voltage to
shift
the
key
in
which
the
sequencer
plays.
9
Quantizer
Inputs:
Allows
voltages to
be
"quantized" (rounded
to nearest
1/12
volt).
Prepatched
to the
sequencer
out-
puts.
10
Sequencer Outputs:
Provides
a
to
+10
volt
analog control
voltage.
1 1
Common
convenience
jacks.
12
Pulse
Width:
Varies the pulse
width
of
the clock.
13
Clock
FM:
Allows
external control
volt-
ages to increase the
speed
of the
clock
(prewired
to
Gate Bus
1 ).
14
Clock Frequency:
Manually
varies
the
clock
rate
from
.2Hz
to
approx.
100
Hz.
15
Start/Stop: Alternately
starts
and
stops
the sequencer.
16
Trig/Gate
Switch:
Trigger
mode
allows
the
sequencer
to
be "triggered"
on.
In
the
Gate
mode,
the
sequencer
is
on
while the
start
button
is
held.
1
/
Externally
starts
the sequencer.
18
Externally stops the sequencer.
19
Step:
Advances
the
sequencer
to
the
next
position.
20
Reset: Resets the
sequencer
to position
1
(sequential
mode
only).
21
Skip/Reset: Allows
particular positions
(from
gate
bus
3) to
either skip past
or
reset
on
particular positions.
22
Sequential/Random
Mode:
Allows
clock
to
advance
to
each
successive position or
advance
to
a
random
position.
23
Mode
Switch: Steps the sequencer 16
times, or steps
banks
A
and B 8
times
in
parallel.
24
LEDs:
(Light
Emitting Diodes)
Indicates
which
position
is
on.
25
Position
Tuning
Sliders:
Tunes
individual
positions
(adjusts
CV
level).
