tuning reference?

[Matt Haines]

How can I build a tuning reference? I'm getting a bit tired of having to
act like an octopus to get my Odyssey in tune to another keyboard. I'd love
to be able to just flip a switch, and A440 would sing sweetly through my
speakers. Is it simple to do? Seems like it must be...a crystal and an
output, and a few of them resistors for looks. Anyone have a schematic?
This will be even more important when I get some working modules on my
M0D00LAR. Which will be very soon. Thanks.
