A-157

A-157 is a trigger sequencer subsystem that is used to generate up to eight trigger signals controlled by a 8×16 LED/button matrix (some customers call it “Miniature Schaltwerk” as it is based on the same matrix as the no longer available Schaltwerk).

The subsystem contains several modules:

• the LED/button matrix module A-157-1
• the trigger output module A-157-2
• the control module A-157-3

The LED/button matrix module A-157-1 is the core of the subsystem. It is used to set or reset the trigger event on each of the 16 steps of each of the 8 rows.
The trigger output module A-157-2 outputs the 8 trigger signals and has an LED display for each trigger. We will probably add a mute button or mute switch for each row that allows to turn the trigger output off/on independent for each row.
