[sdiy] Sequencer schemataics

[Michael Schulze]

Let me put this another way...

Looking at Hutchins I fine his three basic design suggestions - flip flops,
555, and 74xxx counters.  I like the 555 ability to program individual step
times, but I think I would rather do that with a very flexible VC pulse
generator, or perhaps a separate 1 or 2 row sequencer just to drive the big
one.  It looks to me like the 300k pots ought to work fine as whatever I am
feeding the DC outputs to should draw very little current, and anyway I
guess I will opamp buffer the outputs so I can add an offset input to each
channel output.

So I am looking for suggestions based on anybody's success/faliure ratio
with the above mentioned approaches...

"opamp buffer the outputs so I can add an offset input to each channel
output" - that's a good one.  Sounds like one of my Sony manuals.
