Doepfer A-155-2 Compact Analog Sequencer

Module A-155-2 is a small, very compact designed analog sequencer with a lot of features. The sequence length is 8 steps. Each step has available a control for the adjustment of the control voltage for this step and an illuminated momentary switch (button). The buttons are used in the standard running mode to turn on/off the gate of the step in question (button illuminated = gate on, not illuminated = gate off). In combination with other controls at the bottom of the front panel the buttons are used for additional functions: depending on the position of the Program toggle switch the button Function is used to program the length of the sequence (switch position Limit), the running direction (switch position Direct.) or to call up the preset management (switch position Preset).
