Great. I rigged up a 556 on a breadboard tonight and it worked. Even
have a trigger LED on the output..whee
I have a 1 meg pot which seems to give good control of gate on time,
but the adjustments are all bunched up at the start of the pot(full
cc). I guess its a log vs. linear thing...not sure what pot I have,
but I'll dig around for another.
I get the ssg or comparitor output drive the 556 and this inturn
drive a SCi Pro One seq and it works....got a love analog.
thaks for the suggestions, I'll look for a 7555. btw -I have a 1 meg
pot and 4.7uf for the timing discharge cap.
