Hi all,
I've been working on a little 8 step CV sequencer project, and I'm getting
odd results.
Here is the schematic;

As you can hopefully see(sorry for the bad schematic), I am attempting to
use the reset and a 1P8T switch to chose how many steps are used. Another
switch SPDT, enables or disables the chip.
After much trouble shooting, I've gotten rid of any errors that I could
find, and still there is an issue. S1 works when it's selected for 1-4
steps, but jams on 5 when selected to run 5-8 steps. When stuck at step 5,
it seems that ALL of the pots effect the CV that is output.
If anyone can help me, with the information that I've given, I would be very
thankful. It already makes a really fun 1-4 step sequencer, so I really
want the whole project to work.
Thanks!
Pat
