Line 6:
This module replicates the programmer, but with one major exception - up and down inputs allow it to be sequenced without connection to an external gate source. Any stage can be activated at any time by a direct pulse or button press. Up or down pulses will then step it from that stage. To limit the number of steps in the sequence, the pulse (gate) output of a stage is simply routed to the external pulse input for the first stage of the sequence. Note that the first stage used in a sequence need not be the first stage on the panel. For example it would be possible to have the first few stages used as an "introduction", with the sequence automatically looping to a stage in the middle of the panel once the sequence's first run was completed.
 
There is also no theoretical limit to the number of stages that can be used, though I have only tested to a maximum of 10 stages. The maximum number of stages is of course chosen prior to building. The astute will recognize the circuits as having grown from that published in the [[Synapse: The Electronic Music Magazine|Synapse]] March/April 1977 article. Make no mistake - it wasn't simply copied. Hundreds of hours of R&D and numerous prototypes were needed to get it right, as the circuit has been taken far beyond its original intentions.
