Hey hey,
I'm experimenting with c++ trying to program something nice for MIDI. I'm now
experimenting with clocks, using both the standard c++ chrono library and the
boost chrono library. My example program sets a desired delta between ticks of
250ms. I see that there is a difference, since Boost chrono can also use
pthread thread parameters foor realtime scheduling and priorities.
With the standard chrono and thread library my ticks are usually out by
anything between 150.000 to 290.000 nanoseconds. Using boost a tick is out
anything between 110.000 to 124.000 nanoseconds. Yes, much better. But,
assuming that I correct the drift, does it make a difference for MIDI
instruments?
I know one of my MIDI instruments with a clock sync'able delay can be rather
touchy with MIDI clocks, but are there good estimated guidelines experience
values how precise ticks should be?
Best wishes and thanks for any help,
Jeanette
