Sequence up to four destinations at once, with the Doepfer A-155 Analog/Trigger Sequencer Module. It offers four trigger/gate tracks — three of them send a quick pulse, and one sends a gate signal for the length of the step. Two rows of routing switches allow you to change step destinations on the fly. You can use CV and external audio alike as inputs for each step too — creative patching here will reward you with unique sonic results. Whether you're using it to modulate filters and effects, create note sequences, or both at once, synthesists at Sweetwater agree that the Doepfer A-155 Eurorack Analog/Trigger Sequencer Module offers big creative potential.
