Hi all,

I am now designing a electronic metronome for myself, PIC-based of course.
As an extra, since I'm using crystal precision anyway, I thought of including a 440 Hz (an A note) reference tone to tune flutes etc.
But I can't find any standard (cheap) crystal that divides nicely in 440 Hz.
Do you know a simple solution, that does not introduce audible jitter (that would effectively ruin the use as a tuner)?
Are self-adjusting timer loops good enough?

Well, thanks in advance again,

Koen van Leeuwen
