Introduction
The Behringer CLOCKED SEQUENTIAL CONTROL MODULE 1027 is a faithful reproduction of the legendary 2500 Series 8-position step sequencer. Designed for Eurorack systems, this module provides precise control over voltage and gate signals, making it an essential tool for creating complex melodic and rhythmic patterns in your modular synthesizer setup. Its robust design and intuitive interface ensure reliable performance and creative flexibility.
Important Safety Instructions
- Read these instructions thoroughly before operating the module.
- Keep these instructions for future reference.
- Heed all warnings on the product and in the manual.
- Follow all instructions for safe operation.
- Do not use this apparatus near water or moisture.
- Clean only with a dry cloth.
- Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
- Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
- Only use attachments/accessories specified by the manufacturer.
- Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way.
Setup
Eurorack Installation
The CLOCKED SEQUENTIAL CONTROL MODULE 1027 is designed for installation into a standard Eurorack case. Ensure your Eurorack case has sufficient power and space (16 HP width) before installation.
- Power Off: Always disconnect power from your Eurorack case before installing or removing any modules.
- Mounting: Align the module with an available 16 HP space in your Eurorack case. Secure it using the provided screws.
- Power Connection: Connect the 16-pin power cable from your Eurorack power supply to the module's power header. Ensure the red stripe on the cable aligns with the -12V pin on both the module and the power supply. Incorrect connection can damage the module and/or power supply.
- Power On: Once securely mounted and connected, you can power on your Eurorack case.

Initial Connections
To begin using the 1027, connect its outputs to other modules in your Eurorack system. Common connections include:
- Clock Input (CLK IN): Connect a clock signal from another module (e.g., an LFO or clock divider) to the CLK IN jack to drive the sequencer.
- CV Outputs (CH A, CH B, CH C): Patch these outputs to the CV inputs of oscillators, filters, or other modules to control pitch, cutoff, or other parameters.
- Gate Outputs (POSITION GATES 1-8): Connect these to gate inputs of envelope generators or drum modules to trigger events at specific steps.

Operating Instructions
Overview of Controls
The 1027 module features a clear layout of controls for intuitive sequencing:
- RATE Knob: Adjusts the speed of the internal clock. The range switch (LOW/HIGH) selects the clock speed range.
- PULSE WIDTH Knob: Controls the width of the gate pulses. The switch (INT/EXT) selects between internal control or external CV control.
- ON/OFF Switch: Toggles the sequencer's operation.
- STEP Buttons (1-8): Each step has a corresponding button to activate/deactivate it.
- CV Knobs (A, B, C for each step): Adjust the control voltage output for each of the three channels (A, B, C) at each step.
- POSITION GATES (1-8): Individual gate outputs for each step.
- STEP/RESET Buttons: Manual step advance and reset functions.

Creating a Sequence
- Set Clock: Use the RATE knob and LOW/HIGH switch to set the desired tempo. Alternatively, connect an external clock to the CLK IN jack.
- Activate Steps: Press the STEP buttons (1-8) to activate the desired number of steps in your sequence. Active steps will typically illuminate.
- Adjust CV: For each active step, turn the CV Knobs (A, B, C) to set the voltage level for each channel. These voltages will be outputted sequentially.
- Configure Gates: The POSITION GATES will output a pulse when their corresponding step is active. Use these to trigger envelopes or other events.
- Start/Stop: Use the ON/OFF switch to start and stop the sequence.
Advanced Features
- External Pulse Width Control: Connect a CV source to the EXT input for the PULSE WIDTH section to dynamically control the gate pulse width.
- Manual Step/Reset: The STEP and RESET buttons allow for manual control over the sequence progression, useful for live performance or precise programming.
Maintenance
Cleaning
To maintain the appearance and functionality of your module:
- Always power off your Eurorack system before cleaning.
- Use a soft, dry, lint-free cloth to wipe the module's surface.
- For stubborn dirt, slightly dampen the cloth with water. Avoid using harsh chemicals or abrasive cleaners.
- Do not allow any liquids to enter the module through jacks or openings.
Storage
When not in use for extended periods, store the module in a cool, dry place, away from direct sunlight and extreme temperatures. If removed from the Eurorack case, store it in anti-static packaging.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Module does not power on. | Incorrect power cable connection; Eurorack power supply off or faulty. | Check power cable orientation (red stripe to -12V). Ensure Eurorack power supply is on and functioning correctly. |
| Sequencer not advancing steps. | No clock signal; ON/OFF switch is OFF; RATE knob set too low. | Connect a clock signal to CLK IN. Ensure ON/OFF switch is ON. Increase the RATE knob setting. |
| No CV output from a channel. | CV knob for that step/channel is at minimum; step is not active. | Adjust the corresponding CV knob. Ensure the step is active (illuminated). |
| No Gate output from a position. | Step is not active; PULSE WIDTH set to minimum. | Ensure the step is active. Increase the PULSE WIDTH setting. |
