1. CH A / CH B / CH C SEQUENCER COLUMNS – Use the knobs to set the
control voltage output for each step. Each column sends out control voltages
via that channel's respective CH A / CH B / CH C output jack.
2. STEP LEDs – Each LED lights to indicate its respective sequencer step is active.
3. POSITION GATES – Each of these output jacks sends out a gate signal for its
respective sequence step via cables with 3.5 mm TS connectors. These 8 gate
output signals are also available via the 12-pin GATE OUT LINK CONNECTOR
located on the module underside. This 12-pin connector can connect to and
trigger other compatible modules, such as the MIX-SEQUENCER MODULE
1050, via a 12-pin ribbon connector.
4. RATE – This knob controls the step speed at which the sequencer moves
from step to step. The knob operates in two overall frequency ranges
determined by the LOW/HIGH switch.
5. LOW/HIGH – Use this sliding switch to set whether the RATE knob operates
in a lower-frequency (LOW) or higher-frequency (HIGH) range.
6. % PULSE WIDTH – Select between width settings for the rectangular
waveform ranging from 5% to 95% duty cycle. The PULSE WIDTH control
operates on the CLK OUT jack only, making this control very useful for
triggering other modules such as envelope generators, and so on.
7. INT/EXT – Use this switch to select between internal (INT) or external (EXT)
pulse width control voltage. When EXT is selected, the % PULSE WIDTH
control knob is disabled.
8. ON /OFF – This button starts or stops the sequence with a manual button push.
9. STEP – Press this button to manually progress to the next sequencer step.
10. RESET – Press this button to manually restart the sequence at step 1.
11. STEP – Use this jack to route external trigger signals for the STEP button into
3
the module via cables with 3.5 mm TS connectors.
12. RESET – Use this jack to route external trigger signals for the RESET button
into the module via cables with 3.5 mm TS connectors.
13. ON – Use this jack to route external trigger signals to enable the step
counter into the module via cables with 3.5 mm TS connectors.
14. OFF – Use this jack to route external trigger signals to disable the step
counter into the module via cables with 3.5 mm TS connectors.
15. RATE – Use this jack to route in external control voltage signals for the
sequencer's step speed (usually controlled by the RATE knob) via cables with
3.5 mm TS connectors.
16. WIDTH – This jack allows control voltage and modulation signals for the
rectangular waveform to be routed in via cables with 3.5 mm TS connectors.
17. CH A – This jack sends out control voltage signals for the CH A sequencer
column via cables with 3.5 mm TS connectors.
18. CH B – This jack sends out control voltage signals for the CH B sequencer
column via cables with 3.5 mm TS connectors.

19. CH C – This jack sends out control voltage signals for the CH C sequencer
column via cables with 3.5 mm TS connectors.
20. CLK OUT – Use this jack to export the internally generated clock signal via
cables with 3.5 mm TS connectors. The internal clock produces a gate pulse
every time the sequencer steps, and the gate pulse's width can be adjusted
using the % PULSE WIDTH control or via the WIDTH control jack.
Power Connection
The CLOCKED SEQUENTIAL CONTROL MODULE 1027 module comes with the
required power cable for connecting to a standard Eurorack power supply
system. Follow these steps to connect power to the module. It is easier to make
these connections before the module has been mounted into a rack case.
1. Turn the power supply or rack case power off and disconnect the power cable.
2. Insert the 16-pin connector on the power cable into the socket on the power
supply or rack case. The connector has a tab that will align with the gap in the
Installation
The necessary screws are included with the module for mounting in a Eurorack
case. Connect the power cable before mounting.
Depending on the rack case, there may be a series of fixed holes spaced 2 HP
apart along the length of the case, or a track that allows individual threaded
plates to slide along the length of the case. The free-moving threaded plates
allow precise positioning of the module, but each plate should be positioned in
the approximate relation to the mounting holes in your module before attaching
the screws.
Quick Start Guide
socket, so it cannot be inserted incorrectly. If the power supply does not have
a keyed socket, be sure to orient pin 1 (-12 V) with the red stripe on the cable.
3. Insert the 10-pin connector into the socket on the back of the module.
The connector has a tab that will align with the socket for correct orientation.
4. After both ends of the power cable have been securely attached, you may
mount the module in a case and turn on the power supply.
Hold the module against the Eurorack rails so that each of the mounting holes
are aligned with a threaded rail or threaded plate. Attach the screws part way
to start, which will allow small adjustments to the positioning while you get
them all aligned. After the final position has been established, tighten the
screws down.
