Inspired by the random source on the Buchla
Music Easel, the Gibbon is a digitally controlled
complex random source generating a pair of
both gate and CV signals. The random
generator functions similar to an analog shift
register. When the clock signal triggers an
update and the next register value is loaded,
there is a chance it will change. Think of it
like a sequencer. The random generator cycles
through the steps of the sequence and each
time the sequencer jumps to the next step, there
is a chance the value stored in that step will be
replaced with a new value. The result is a
random source that feels both random and
evolutionary, with an ever evolving pattern
cycle. Add to that adjustable pattern length,
adjustable stored voltage difference range, the
chance for triggers on clock subdivisions, and
the output becomes even more chaotic.

Apparently Gibbons are not very
good at keeping track of large
sequences of numbers.
