Doepfer A-157 Trigger Sequencer
A-157 is a trigger sequencer subsystem that is used to generate up to eight trigger signals controlled by a 8x16 LED/button matrix based based on the same matrix as the no longer available Schaltwerk.
It contains eight rows, each 16 steps, polyrhythmic functions, flexiblly assignable CV inputs and more.
The system is made from three, freely placeable, modules: the master unit, trigger output module and a controller input module.
• Eight trigger outputs
• control inputs: start, stop, reset, clock, four Function CV inputs
The set is made of 3 modules, with a total width 52HP
A-157-1: 44HP wide, 40mm deep
A-157-2: 4HP wide, 35mm deep
A-157-3: 4HP wide, 45mm deep
