The Doepfer A-154 Eurorack Sequencer Controller Module is a competitively priced sequencer controller synth module, specifically designed to control the Doepfer A-155 Analogue/Trigger Sequencer Module.

The A-154 offers new and additional features that are not available in the basic control unit of the A-155. The A-154 can be used to fully replace the control unit of one or two A-155 modules. Key features of the module include:

- Several running modes: forward, backward, pendulum, random, CV controlled step adressing. All modes are available as loop or one-shot.

- Manual and voltage controlled selection (with attenuator) of the running mode.

- Manual and voltage controlled selection (with attenuator) of first and last step of the sequence.

- An internal voltage controlled clock generator with manual and CV control (with attenuator) is available.

- Manual and voltage controlled (with attenuator) pulse width (PW) of the clock signal.

- 8/16 step mode: A toggle switch us used to select 8 or 16 steps.

- If two A-155 are used they can work in parallel (8 steps) or serial (16 steps).
