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. If the A-154 is used to control the A-155 the control section of the A-155 is put out of action.
These are the features of the A-154:
- Several running modes: forward, backward, pendulum, random, CV controlled step adressing. 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
- If the running mode “CV Controlled Step Address” is selected the First Step section is used to determine the active sequencer step.
- An internal voltage controlled clock generator with manual and CV control (with attenuator) is available.
- Manual and voltage controlled (with attenuator) pulse width (PW) of the clock signal. This features can be used to obtain a different gate length for each step.
- 8/16 step mode: A toggle switch us used to select 8 or 16 steps.
