Behringer 1027 Clocked Sequential Control Module

Description

Behringer 1027 Clocked Sequential Control Module

The Behringer 1027 Clocked Sequential Control Module is an analog step sequencer designed for Eurorack modular synthesizer systems. Based on the classic 2500 Series modular architecture from the 1970s, this module provides musicians and sound designers with an eight-position step sequencer capable of generating multiple control voltages for evolving sequences, rhythms, and modulation patterns.

The module contains an integrated 8-step counter with three independent channels of control voltage output labeled A, B, and C. Each step includes three adjustable voltage controls, allowing precise voltage programming for each stage of the sequence. LED indicators next to each row provide clear visual feedback of the sequencer position during operation.

An internal clock generator allows the sequencer to run automatically, with adjustable stepping speed controlled by the Pulse Repetition Frequency and external rate inputs. Pulse width control allows the duration of each step to be adjusted from 0 to 100 percent. The module can also be manually stepped or reset using front-panel controls, and it integrates with other 2500 Series modules such as the 1026 Preset Voltages and 1050 Mix Sequencer for expanded modular sequencing capabilities.
