The Programmer/Sequencer is a Serge
inpired multi-stage sequencer. Unlike most
sequencers, this one makes no use of binary
counters. Rather, it uses a set of individual
stages, each one directly accessible. As such
it could be considered to allow "random
access".
This module replicates the
programmer, but with one major exception -
left and right 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. Left/right
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. The
maximum number of stages is, of course, chosen
prior to building.
In
addition to the individual 'stage' outputs,
two additional outputs are provided:-
- CPO - Common Pulse Out. Goes high
and remains high while a stage is 'selected'
via either the [STAGE x] input or the
[MANUAL x] button.
- AEP
- All Event Pulse. Gives a trigger pulse on
any change of stage.
