Module A-154 is a supplement to the Analog/Trigger Sequencer A-155. 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. If the A-154 is used to control the A-155 the control section of the A-155 is put out of action.

Vintage Edition with black front panel.

Features

  • 5 different running modes: forward, backward, pendulum, random, CV controlled step addressing. All modes are available as loop or one-shot
  • Manual and voltage controlled selection (with attenuator)of the running mode
  • 5+1 LED display for the 5 different current modes and one LED for loop/one-shot display
  • Manual and voltage controlled selection (with attenuator)of first and last step of the sequence
  • In the "CV Controlled Step Address" mode the First Step section is used to determine the active sequencer step (in this mode the first/last step feature is not available). Consequently manual and voltage controlled selection of the active step is possible
  • Internal voltage controlled clock generator with manual and voltage controlled (with attenuator)clock rate, enables variable time length for each step, e.g. controlled by one of the analog rows of the A-155
  • Skipping of steps, e.g. the gate row of the A-155 can be used to control the skipping of steps
  • LED display of the clock signal
  • Manual and voltage controlled (with attenuator) pulse length of the clock signal. This features enables different gate length (at the same clock rate) for each step, e.g. one of the CV outputs of the A-155 can be used to control the PW
  • One or two A-155 can be controlled from the A-154
  • 8/16 step mode: In combination with two A-155 one can select between parallel (8 steps) or serial operation (16 steps). The serial operation requires additional voltage controlled switches (e.g A-150)
  • Manual and voltage controlled selection between "old" control unit of the A-155 and A-154 control (A-154 Master on/off function)
  • With the One-Shot modes the A-155/A-154 combination can be used e.g. as a complex envelope generator. One analog row determines the levels of the envelope. The second analog row can be used to adjust the time length for each step
  • The A-154 requires at least one A-155
