the project page is quitte.de/nam.html (be warned that building it
will probably take a seasoned pilot).

the RTC thread is run by the RTClock object, the MIDI clock signal is
calculated in Graph::process_time(), and finally the MIDI out
bytestream is written in MidiOut::process_time(). there's a
documentation file going with the package that discusses the
interaction of the various objects a bit.

MIDI event timing is calculated from a tempo map, so iirc, this
differs a bit from your objective. still, i hope you'll find it
useful.
