Doepfer - A-155-3 1U Mini Analog Sequencer

Module A-155-3(1U) is the 1U version of the A-155-2. The functions of A-155-3 are exactly the same as for the A-155-2. Only the positions of the controls and sockets are different because of the 1U format.

The Doepfer A-155-2 is a Miniature Analog Sequencer module that packs huge creative potential in a compact package. Using the A-155-2 is simple, yet a deep set of functionalities make it perfect for all things from basic repeating patterns to unique ratcheting and evolving sequences. Eight step positions each feature a knob for setting CV value, as well as an illuminated button to manually set gates on each step. At the bottom of the panel, outputs for a single pair of CV and gate signals are available, as well as clock and reset inputs. Along with a simple three-position switch for CV range, the A-155-2 offers a streamlined way to create driving patterns in any patch.

Beyond simple and unidirectional patterns, the A-155-2 enables plenty of creative options for crafting unique and lively sequences. Using the programming switch in combination with the step buttons, you can easily set up ratcheting rhythms for multiple gates per step, perfect for extending a melodic idea with stuttering syncopations. Additionally, sequence length and direction can be adjusted, allowing you to create longer patterns, evoke odd-time signatures, and experiment with random step playback. Finally, an eight-slot preset system is onboard, giving you the capability to store and recall your patterns between sessions and shows. Whether implemented as the brain of a small system or ticking along in a grand chorus of clocked control, the Doepfer A-155-2 Mini Analog Sequencer is a small triumph of modulatory movement for any case.
