No problem sir.. I understand about long work days..
I think in many cases when people get together to play music for fun
they usually just tune their instruments so they are in tune with
each other. Even an individual may only check tuning between the
strings on a stringed instrument..
I didn't mean to sound condescending. In the beginng it just seemed
interesting that a person could get a app that would make it wasy to
tune a musical instrument. Instead of having a tuning fork/s to keep up
I guess it's just the nerd in me.
On the logic circuit design. I hadn't thought about TTL for years. I built a digital clock
from scratch for my father in the late 1970's. He had been fussing that he couldn't find
a good digital clock with the day of the month on it. So I bread boarded one out, then built
it up with wirewrap.. Still works. I built a few other things, but it was always fun building
things like that. I did get into some programing too, but just as a hobby..
