! Trigger Outputs
Sockets ! are the outputs from the three trigger rows
and the gate row.
"
Control
Alongside the four buttons for sequencer control, there
are four corresponding digital control input sockets ".
• Start
: A signal here starts the sequence.
• Stop
: A signal here stops the sequence.
• Clock
:A clock signal here steps through the
sequence. Also called ‘step’ input.
• Reset
: A signal here sends the sequence back to
step one.
H
Start
and
Stop inputs
work in
trigger
mode.
As soon as they sense the rising edge of a
pulse, they produce a momentary signal.
The length of the pulse makes no difference
- a pulse of long duration still just produces a
momentary trigger.
Clock (step)
and
Reset inputs
, on the other
hand, work by sensing level: so, for instance,
Reset will always be active (keeping the
sequence at step one) as long as the reset
signal is "high".
§ CV outputs, control inputs
The two groups of sockets
§
contain the analog CV
outputs
for each row, and the
digital control inputs
for the sample-and-hold and slew limiter sections.
The upper group of sockets relates to analog CV row
1, and the lower to analog CV row 2.
• Pre Out
:The
control voltages
set on the
respective analog CV row are output
here, before (pre) passing through the
slew limiter and sample-and-hold sec-
tions.
• Post Out
:The control voltages set on the
respective analog CV row are output
here,
after
(post) passing through the
slew limiter and sample-and-hold sec-
tions.
