DOEPFER / A-157 Trigger Sequencer Set

Variations

This is a subsystem of a trigger sequencer consisting of three modules for the DOEPFER Eurorack modular synthesizer. Connect the three modules (A-157-1, A-157-2, and A-157-3) to create a trigger sequencer with up to 16 steps x 8 tracks. You can program rhythm patterns using a matrix and play drum modules and other sounds triggered by the signal.

The A-157 is a trigger sequencer subsystem set consisting of three modules. By connecting the three modules—A-157-1, A-157-2, and A-157-3—you can build a trigger sequencer with up to 16 steps x 8 tracks. You can program rhythm patterns using the matrix and play drum modules and other triggers.

A-157-1 8 x 16 Trigger Matrix
This is the core trigger matrix module of the A-157 subsystem. The 16-step x 8-track matrix is used not only for programming sequence steps but also for setting various functions such as first/last step settings.

A-157-2 Trigger Out
This trigger out module outputs the triggers of patterns programmed in the A-157-1. It features 8 trigger output jacks. The trigger output is up to 12V, and the output level can be set via software. It includes LEDs for visual confirmation of operation.

A-157-3 Control Input
A simple control input module for the A-157 subsystem. Features four inputs: Start, Stop, Reset, and Clock. *Func.1-4 are not currently functional as of August 2016.

The three modules are connected via a ribbon cable on the back.
