Thanks for the thoughts and links Chris, but I struggle to write C++
and that's with the great help of Qt Creator. Moving around a large
music file with jack_transport is so much better than what I had
before and showtime is tamed a bit with the solution I was given on
Stack Overflow.

But, looking at showtime.c I wonder if I could modify it to print just
the first value on the line and then sleep for a while. Would it build
somewhere under ~/ and work?

Thanks again, John.
