Module A-161 is an eight-step Clock Sequencer which is internally connected to the Clock Divider (A-160). Eight outputs are sequentially switched by the clock signals from the A-160 (see Fig. 1) and can act, for instance, as sequential rhythmic triggers for an envelope. The reset on the A-160 also works on the A-161 (instant return to Step 1). The low/high levels of the output signals are 0V and about +10V. In combination with a mixer (A-138) short analog sequences can be generated.
