Doepfer A-157 Trigger Sequencer (Module Set A-157-1/2/3)

The Doepfer A-157 is a full-featured 8x16 trigger sequencer system for Eurorack, composed of three modules: the A-157-1 (LED display matrix), A-157-2 (64-button control interface), and A-157-3 (logic/control board). Together, they form a powerful step sequencer with 8 rows of 16 steps each, perfect for creating complex rhythmic patterns, drum programming, and trigger-based modulation. The highly tactile interface and immediate visual feedback make it ideal for both live performance and detailed studio composition. Store, edit, and activate trigger patterns with precision—essential for advanced rhythmic control in modular setups.
