Doepfer A-157

Doepfer's A-157 Trigger Sequencer Subsystem is a series of three modules that work together to form an intensely powerful battery of programmable trigger sources. Offering eight tracks of trigger sequencing, this module set is perfect for systems in need of a centralized source of clear, detailed rhythmic control. The A-157-1 Trigger Matrix offers button control of all module options, from trigger programming to muting, editing functions, and more. A-157-2 provides all of the trigger outputs, and A-157-3 provides the system's external control inputs, including start gate input and button, stop gate, reset gate, clock input, and four programmable functions.
