I think the point is not to choose between a processor based sequencer and
an analogue sequencer, but to build a processor based, analogue sequencer.
Once you have all your knob and switch scanning circuitry built, and the
processor board attached, you only have to make software changes as you
devise new features, or changes in operation that you think of after you
have built the hardware.
It would be harder to make changes to your discrete hardware design.
At the very least, you can build an exact functional copy of your favourite
analogue sequencer, but add midi output and pattern storage.
