Module A-154 is a supplement to the A-155 Analog/Trigger Sequencer module. It offers a lot of new features that are not available in the basic control unit of the A-155. The A-154 is used to replace the control unit of one or two A-155, i.e. the section marked "Control" with Start / Stop / Step / Reset buttons and inputs in the upper left corner of the A-155 front panel.

Key Features:

• Several running modes: forward, backward, pendulum, random, CV controlled step addressing. All modes are available as loop or one-shot
• LED display of the 5 different current modes and one LED for loop/one-shot display
• Manual and voltage controlled selection (with attenuator) of the running mode
• Manual and voltage controlled selection (with attenuator) of first and last step of the sequence
