I don't fully understand the CGS sequencer, but it got me thinking
about doing a sequencer in 4 stage slices. It seems like you could
use one of the inexpensive AVR processors, like the ATMEGA8, couple it
with an inexpensive quad DAC like the AD5726, and have a neat little
slice. 4 of the 10 bit A/Ds could be for sequencer controls and two
could be used to for an input control CV. Other I/O could be used for
clocks and carry in/outs for daisy chaining these slices together.
You could parallel and series connect as many as you want, and use the
carry out / carry in to transfer clock control from slice to slice.
Or you could run them all off a master CV, such as a ramp or triangle,
and use an offset control to set a range of the CV for each slice to
operate in without any master clock. You could even get fancy with
the serial interfaces to pass control or data between slices or
driving an LCD. Quite expandable. So far this is only 2 inexpensive
chips per slice plus appropriate buffers. There is enough I/O on an
ATMEGA8 for all sorts of gate outputs, LED indicators, etc.

Food for thought (actually, out of current modular projects).
