AHHHHH!!! I just finished up my new MyTimer Library plus 2 Examples. One is a Midi Clock at 960 PPQ, and it works great! Doesn't miss a pulse at all. I played it into my notebook and its perfect. The clock is like 0.1% slower than what other clocks I tested, but that's why they created MIDI-Sync messages for. In any event, this is a MASTER clock, so I don't really care if its 0.1% slower than other devices BPM clocks.
I uploaded a new ZIP file and will also post the new examples here.
