INVENTORY #58380

BRAND: Doepfer

MODEL: A-155 Analog / Trigger Sequencer

FUNCTION: Eurorack Synthesizer Module

PRODUCT DESCRIPTION: This listing is for a Doepfer A-155 Analog / Trigger Sequencer Eurorack Synthesizer Module. The Doepfer A-155 Analog / Trigger Sequencer is a classic 8-step sequencer module for Eurorack modular systems, designed to simultaneously produce analog voltages and trigger/gate signals. It is highly regarded for its hands-on, "no-menu" interface and its ability to act as a versatile controller for VCO pitch, filter modulation, or complex rhythmic patterns.

SPECS:

• Sequencing Rows: Features two analog rows of eight knobs each. The upper row includes a range switch (1V/2V/4V) for precise pitch control, while the lower row can accept external audio or CV signals for each step, with the knobs acting as attenuators.
• Trigger and Gate Tracks: Includes four trigger/gate tracks with two rows of three-position switches (1-0-1 type), allowing you to route signals to different outputs or mute them per step.
• Slew and Glide: A built-in glide control (slew limiter) and Sample & Hold (S&H) section allow for smooth transitions or stepped changes between voltages, controllable via dedicated CV inputs.
• Manual Controls: Features dedicated buttons and CV inputs for Start, Stop, Step (Clock), and Reset functions.
• Expansion Potential: Its capabilities can be significantly expanded by pairing it with the Doepfer A-154 Sequencer Controller, which adds voltage-controlled addressing, various playback modes (backward, random, pendulum), and step-skipping
• Width: 50 HP.
• Depth: 40 mm (~1.57 inches).
• Current Draw: 100 mA at +/-12V (some sources list specific draws of +80mA / -20mA).
