Mini analog sequencer

The patch in Fig. 5 produces a four-step mini analog
sequencer.

A clock signal either from an LFO, or a MIDI-CV
interface (A-190) sequentially steps through the A-
161’s outputs. These are fed into the inputs of an
A-138a linear mixer.

Whan an A-161 is active, it puts out a +5 V signal. Use
the input attenuators on the A-138 to set each of the
voltages in the sequence.

The mixer output then sends out a sequence of control
voltages, which can be patched to one or more VCOs.
The clock signal can be patched to one or more ADSR
CV inputs.

After four clock pulses, output % on the A-161 resets
A-160, and the sequence begins again from step 1.

By adding another A-138a you can extend the se-
quence up to eight notes.
