[sdiy] ...dumb question (CD4017 sequencer)

[John Blacet]

"How do you get the sequencer to stop so that it - A) does not put out
the voltage of the current step and B) always starts again
on step 1, when you restart it?"

---Well "A" is not a "normal" sequencer function in most cases. When you
stop a sequencer, it usually puts out the step voltage. The desired
silence is typically a function of turning off the VCA in a patch (via a
gated ADSR, for example). So you may wan tto think of having a gate out
if you don't already.

You *could* use an analog switch connected to the seq out and control it
via the seq start/stop to remove any voltage out when the seq is
stopped.

Having the 4017 *reset on start *requires a bit of external logic
between the start/stop and the 4017 reset pin. You might want to try a
very short pulse from the rising edge of the "start".

While the 4017 looks like a sequencer on a chip, getting it to do the
usual seq functions is a bit complicated. You will probably find some
circuits on the web if you do a search.
